Abstract
Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is a common and serious disease with unclear pathogenesis and recurrent symptoms. Hedyotis diffusa Willd (HDW) has been recognized for its potential in managing various chronic inflammatory diseases. This research aimed to interrogate the mechanism of HDW in treating CP/CPPS. Complete Freund Adjuvant (CFA) and LPS were utilized to establish the rat and cell models of CP/CPPS. Results showed that HDW decreased levels of inflammation-related factors in CP rat prostate tissue and LPS-elicited RWPE-1 cell injury model. Moreover, HDW administration impaired oxidative stress in the prostate and RWPE-1 cells. In addition, HDW treatment activated the NRF2/ARE signaling in rat prostate tissue and cell models. Interestingly, NRF2/ARE pathway inhibitor ML385 reversed the inhibition effects of cell apoptosis, inflammation, and oxidative stress triggered by HDW. In summary, HDW alleviated inflammation and oxidative stress by activating NRF2/ARE signaling in CP/CPPS rat model and human prostate epithelial cell injury model.

Abstract
Calcium/calmodulin-dependent protein kinase IV (CaMK4) is a versatile serine/threonine kinase involved in various cellular functions. It regulates T-cell differentiation, podocyte function, tumor cell proliferation/apoptosis, β cell mass, and insulin sensitivity. However, the underlying molecular mechanisms are complex and remain incompletely understood. The aims of this review are to highlight the latest advances in the regulatory mechanisms of CaMK4 underlying T-cell imbalance and parenchymal cell mass in multiple diseases. The structural motifs and activation of CaMK4, as well as the potential role of CaMK4 as a novel therapeutic target are also discussed.

Abstract
Prostatitis represents a common disease of the male genitourinary system, significantly impacting the physical and mental health of male patients. While numerous studies have suggested a potential link between immune cell activity and prostatitis, the exact causal role of immune cells in prostatitis remains uncertain. This study aims to explore the causal relationship between immune cell characteristics and prostatitis using a bidirectional Mendelian randomization approach. This study utilizes data from the public GWAS database and employs bidirectional Mendelian randomization analysis to investigate the causal relationship between immune cells and prostatitis. The causal relationship between 731 immune cell features and prostatitis was primarily investigated through inverse variance weighting (IVW), complemented by MR-Egger regression, a simple model, the weighted median method, and a weighted model. Ultimately, the results underwent sensitivity analysis to assess the heterogeneity, horizontal pleiotropy, and stability of Single Nucleotide Polymorphisms (SNPs) in immune cells and prostatitis. MR analysis revealed 17 immune cells exhibiting significant causal effects on prostatitis. In contrast, findings from reverse MR indicated a significant causal relationship between prostatitis and 13 immune cells. Our study utilizes bidirectional Mendelian Randomization to establish causal relationships between specific immune cell phenotypes and prostatitis, highlighting the reciprocal influence between immune system behavior and the disease. Our findings suggest targeted therapeutic approaches and the importance of including diverse populations for broader validation and personalized treatment strategies.

Network pharmacology and in vivo experiment-based strategy for investigating the mechanism of chronic prostatitis/chronic pelvic pain syndrome in QianLieJinDan tablets. Heliyon 2024; 10:e29975. [PMID: 38726171 PMCID: PMC11078777 DOI: 10.1016/j.heliyon.2024.e29975] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 04/17/2024] [Accepted: 04/18/2024] [Indexed: 05/12/2024] Open
Abstract
Background Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common urinary system disease that is prone to recurrence. It typically leads to varying degrees of pelvic pain and discomfort, as well as symptoms related to the urinary system in affected patients. QianLieJinDan tablets (QLJD), a traditional Chinese medicine, have shown promising therapeutic effects on CP/CPPS in clinical practice, but the underlying mechanisms of QLJD in treating CP/CPPS have not been determined. Objective To reveal the phytochemical characterization and multitarget mechanism of QLJD on CP/CPPS. Methods The concentrations of the components of QLJD were determined using UHPLC-Q Exactive Orbitrap-MS. Utilizing network pharmacology approaches, the potential components, targets, and pathways involved in the treatment of CP/CPPS caused by QLJD were screened. Molecular docking calculations were employed to assess the affinity between the components of the QLJD and potential targets, revealing the optimal molecular conformation and binding site. Finally, the therapeutic efficacy and potential underlying mechanisms of QLJD were investigated through pharmacological experiments. Results In this study, a total of 35 components targeting 29 CP-related genes were identified, among which quercetin, baicalin, icariin, luteolin, and gallic acid were the major constituents. Enrichment analysis revealed that the potential targets were involved mainly in the regulation of cytokines, cell proliferation and apoptosis, and the oxidative stress response and were primarily associated with the cytokine‒cytokine receptor interaction pathway, the IL-17 signaling pathway, the Th17 cell differentiation pathway, and the JAK-STAT signaling pathway. In vivo experiments demonstrated that QLJD effectively attenuated the infiltration of CD3+ T cells and the expression of ROS in a CP/CPPS model rat prostate tissue. Furthermore, through the inhibition of IL-6 and STAT3 expression, QLJD reduced the differentiation of Th17 cells, thereby ameliorating pathological injury and prostatic index in prostate tissue. Conclusion The potential of QLJD as an anti-CP/CPPS agent lies in its ability to interfere with the expression of IL-6 and STAT3, inhibit Th17 cell differentiation, reduce inflammatory cell infiltration in rat prostate tissue, and alleviate oxidative stress damage through its multi-component, multi-target, and multi-pathway effects.

Abstract
Introduction Chronic Pelvic Pain Syndrome or Chronic Prostatitis (CPPS/CP) is the most prevalent urologic affliction among young adult men. It is a challenging condition to treat, which significantly decreases patient quality of life, mostly because of its still uncertain aetiology. In that regard, an autoimmune origin is a prominent supported theory. Indeed, studies in patients and in rodent models of Experimental Autoimmune Prostatitis (EAP) have provided compelling evidence suggesting a key role of CD4 Th1 cells in disease pathogenesis. However, the implication of other prominent effectors of the immune system, such as CD8 T cells, has yet to be studied. Methods We herein analyzed the induction of prostatitis and the development of chronic pelvic pain in EAP using CD8 T cell-deficient animals. Results We found similarly elevated PA-specific immune responses, with high frequencies of specific IFNg+CD4+ and IL17+CD4+ T cells in prostate draining lymph nodes from PA-immunized either CD8 KO or wild type animals with respect to controls. Moreover, these peripheral immune responses were paralleled by the development of significant chronic pelvic pain, and accompanied by prostate histological lesions, characterized by hemorrhage, epithelial cell desquamation, marked periglandular leukocyte infiltration, and increased collagen deposition in both, PA-immunized CD8 KO and wild type animals. As expected, control animals did not develop prostate histological lesions. Discussion Our results indicate that CD8 T cells do not play a major role in EAP pathogenesis and chronic pelvic pain development. Moreover, our results corroborate the previous notion that a CD4 Th1 associated immune response drives the induction of prostate tissue inflammation and the development of chronic pelvic pain.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common inflammatory immune disease of the urogenital system. High glucose intake is considered to be a potential promoter of autoimmune diseases. However, the influence of high glucose intake on CP/CPPS is unknown. This research aimed to explore the influences of high glucose intake on experimental autoimmune prostatitis (EAP), a valid animal model of CP/CPPS, and the underlying mechanism. NOD mice received 20% glucose water or normal water treatment during EAP induction. EAP severity and Th17 cell responses were evaluated. Then, we explored the effects of an IL-17A neutralizing antibody, an inhibitor of TGF-β, the reactive oxygen species (ROS) inhibitor NAC, and the mitochondrial ROS (mtROS) antioxidant MitoQ on glucose-fed EAP mice. The results demonstrated that high glucose intake aggravated EAP severity and promoted Th17 cell generation, which could be ameliorated by the neutralization of IL-17A. In vitro experiments showed that high dextrose concentrations promoted Th17 cell differentiation through mtROS-dependent TGF-β activation. Treatment with TGF-β blockade, NAC, or MitoQ suppressed Th17 cell generation both in vivo and in vitro, resulting in the amelioration of EAP manifestations caused by high glucose intake. This study revealed that high glucose intake exacerbates EAP through mtROS-dependent TGF-β activation-mediated Th17 differentiation. Our results may provide insights into the molecular mechanisms underlying the detrimental effects of an environmental factor, such as high glucose intake, on CP/CPPS.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common and non-lethal urological condition with painful symptoms. The complexity of CP/CPPS's pathogenesis and lack of efficient etiological diagnosis results in incomplete treatment and recurrent episodes, causing long-term mental and psychological suffering in patients. Recent findings indicate that the autonomic nervous system involves in CP/CPPS, including sensory, sympathetic, parasympathetic, and central nervous systems. Neuro-inflammation and sensitization of sensory nerves lead to persistent inflammation and pain. Sympathetic and parasympathetic alterations affect the cardiovascular and reproductive systems and the development of prostatitis. Central sensitization lowers pain thresholds and increases pelvic pain perception in chronic prostatitis. Therefore, this review summarized the detailed processes and mechanisms of the critical role of the autonomic nervous system in developing CP/CPPS. Furthermore, it describes the neurologically relevant substances and channels or receptors involved in this process, which provides new perspectives for new therapeutic approaches to CP/CPPS.

Abstract
INTRODUCTION Chronic pelvic pain syndrome (CPPS) is a common urologic condition that can cause significant disability in affected individuals. Physiologic explanations of chronic pain are often incomplete; appropriate management of CPPS includes recognition of biological, psychological, and social elements, known as the biopsychosocial model. OBJECTIVE The aim of this narrative review is to investigate treatments for men with CPPS, with a special focus on those utilizing the biopsychosocial model of care. METHODS A comprehensive literature search was conducted on the electronic databases PubMed, Embase, and Cochrane Library, using relevant Medical Subject Heading terms and keywords related to CPPS treatments. The search was limited to studies published in English from inception to January 2023. Additionally, reference lists of selected studies were manually reviewed to find studies not identified by the initial search. Studies were included if they investigated pharmacologic or nonpharmacologic treatments for men with CPPS. RESULTS A total of 30 studies met the inclusion criteria. Antibiotics, α-blockers, nonsteroidal anti-inflammatory drugs, gabapentinoids, antidepressants, and phosphodiesterase type 5 inhibitors were among the pharmacologic agents included in trials attempting to reduce symptoms of male CPPS. Studies that focused on treating CPPS without medication included interventions such as shockwave therapy, acupuncture, physical therapy, botulinum toxin, cryotherapy, electrotherapy, exercise, and cognitive behavioral therapy. CONCLUSION α-Blockers and nonsteroidal anti-inflammatory drugs have shown promising results in treating CPPS in men, while the effectiveness of antibiotics remains controversial. Antidepressants and phosphodiesterase type 5 inhibitors may also be useful in decreasing symptoms in patients with CPPS. Treatments such as pelvic floor muscle therapy, acupuncture, shockwave therapy, and cognitive behavioral therapy must be considered effective complements to medical management in men with CPPS. While these interventions demonstrate benefits as monotherapies, the individualization and combination of treatment modalities are likely to result in reduced pain and improved quality of life.

Abstract
BACKGROUND Prostatitis is known as the inflammation of the prostate. The treatments of prostatitis are either pharmacological or non-pharmacological treatment. However, some of the treatments are not effective and very invasive which can lead to side effects. Thus, low-intensity extracorporeal shockwave therapy (LI-ESWT) is used as an alternative treatment for prostatitis due to its convenient and non-invasive procedure. However, a definite protocol for this treatment is not available due to the variability of the treatment protocols and the lack of research comparing the efficacy of these protocols. OBJECTIVE To review and compare the efficacy of different LI-ESWT protocols in treating prostatitis. METHODS The study was performed by comparing the intensity, duration, frequency and combination with different types of pharmacotherapy drugs of the different LI-ESWT protocols from various studies. The finding from various studies which consist of disease improvement and quality of life (QoL) were also presented in this review. RESULT From the findings, the protocol can be categorized into three different intensities which are at 3000 pulses, < 3000 pulses and > 3000 pulses. Most studies reported that each protocol is very effective and safe to use and can improve CP symptoms, urinary symptoms, erectile function and QoL. It is also found that no complications or adverse effects occur to the patient. CONCLUSION Most of the LI-ESWT protocols described are safe and effective in treating CP through the absence of treatment-related adverse effects and maintenance of clinical effects.

Comparing the effectiveness of extracorporeal shockwave therapy and myofascial release therapy in chronic pelvic pain syndrome: study protocol for a randomized controlled trial. Trials 2023; 24:675. [PMID: 37853420 PMCID: PMC10583345 DOI: 10.1186/s13063-023-07633-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Accepted: 09/08/2023] [Indexed: 10/20/2023] Open
Abstract
BACKGROUND Chronic prostatitis/chronic pelvic pain syndrome is a highly prevalent syndrome. Previous studies showed that extracorporeal shockwave therapy and myofascial release therapy could improve the quality of life in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Theoretically, combined therapy with extracorporeal shockwave therapy and myofascial release therapy will likely have significant advantages in treating CP/CPPS. We, therefore, present a protocol for conducting a well-designed randomized controlled trial to compare the efficacy and safety of each therapy. METHODS The proposed study will be a three-group randomized control trial (RCT) design that includes 150 participants from Zhongda Hospital Affiliated to Southeast University, with equal allocation of participants to the three intervention groups. The study duration will be 8 weeks, which includes a 4-week treatment period and a 4-week follow-up period. The primary outcome will be the changes in surface electromyography (sEMG) assessment and National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI). The secondary outcomes will include the changes in three-dimensional quantification, shear wave elastography (SWE), and sympathetic skin response (SSR) testing. Assessments will be conducted before the intervention (T0), before the 5th intervention (T1), immediately after the 8th intervention (T2), and the 4th week after the end of the 8th intervention (T3). DISCUSSION This trial will compare the differences in efficacy between single extracorporeal shockwave therapy, single myofascial release therapy, and combined therapy to select the most appropriate treatment option for patients with CP/CPPS. The possible pathogenesis of CP/CPPS would also be analyzed by comparing the intercorrelation between each objective and subjective measurement (NIH-CPSI score, sEMG, SWE, SSR). TRIAL REGISTRATION The name of the registry: Extracorporeal Shockwave and Myofascial Release Therapy in Chronic Pelvic Pain Syndrome. REGISTRATION NUMBER NCT05659199. Date of registration: December 2022.

Abstract
Prostatitis is a common urological condition that affects almost half of all men at some point in their life. The prostate gland has a dense nerve supply that contributes to the production of fluid to nourish sperm and the mechanism to switch between urination and ejaculation. Prostatitis can cause frequent urination, pelvic pain, and even infertility. Long-term prostatitis increases the risk of prostate cancer and benign prostate hyperplasia. Chronic non-bacterial prostatitis presents a complex pathogenesis, which has challenged medical research. Experimental studies of prostatitis require appropriate preclinical models. This review aimed to summarize and compare preclinical models of prostatitis based on their methods, success rate, evaluation, and range of application. The objective of this study is to provide a comprehensive understanding of prostatitis and advance basic research.

Pain Res Manag 2023; 2023:7754876. [PMID: 36960418 PMCID: PMC10030225 DOI: 10.1155/2023/7754876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Revised: 09/25/2022] [Accepted: 03/04/2023] [Indexed: 03/16/2023]
Abstract
Background Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a complex male dysfunction, mostly seen in young and middle-aged men with a history of more than 3 months. As a traditional therapy of Traditional Chinese Medicine, acupuncture has been proven an effective method to treat CP/CPPS in recent years. Though some meta-analyses on acupuncture for chronic prostatitis were published in 2018 and 2019, most of the included studies were low in quality according to the JADAD score (JADAD < 4). The conclusions of acupuncture for CP/CPPS remain indefinite. Purpose This review aims to evaluate the efficacy of acupuncture for CP/CPPS by including high-quality literature only (JADAD ≥ 4) to provide a reliable basis for clinical applications and research. Method Nine electronic databases were searched from inception to March 1, 2022, and only randomized controlled trials (RCT) with high-quality (JADAD ≥ 4) were included. Data were analyzed using Review Manager 5.3. and was verified through trial sequential analysis (TSA). We carried out a sensitivity analysis for the heterogeneity (I 2 ≥ 50%). Publication bias was explored using a funnel plot. Result Ten RCTs (11 trials) of high-quality methodology involving 798 patients were included. Meta-analysis showed that compared to sham acupuncture (SAT) and western medicine (WM), acupuncture (AT) played superior roles for CP/CPPS patients in pain score, NIH-CPSI score, quality of life score, urinary symptom, and efficacy rate. As for the adverse effects, 4 RCTs described mild hematoma and pain in AT and SAT groups, while specific symptoms including nausea, abdominal pain, dizziness, and low blood pressure were reported in WM groups. Conclusion This meta-analysis indicated that acupuncture has measurable benefits on CP/CPPS, and security has also been ensured. However, this meta-analysis only included 10 RCTs; thus, RCTs with a larger sample size and longer-term observation are required to verify the effectiveness of acupuncture further in the future.

Abstract
The relationship between gut microbiota and pain, such as visceral pain, headaches (migraine), itching, prosthetic joint infection (PJI), chronic abdominal pain (CAP), joint pain, etc., has received increasing attention. Several parts of the evidence suggest that microbiota is one of the most important pain modulators and they can regulate pain in the central and peripheral nervous systems. Any alteration in microbiota by diet or antibiotics mediation may characterize a novel therapeutic strategy for pain management. The present study includes the most up-to-date and influential scientific findings on the association of microbiota with pain, despite the fact that the underlying mechanism is not identified in most cases. According to recent research, identifying the molecular mechanisms of the microbiota-pain pathway can have a unique perspective in treating many diseases, even though there is a long way to reach the ideal point. This study will stress the influence of microbiota on the common diseases that can stimulate the pain with a focus on underlying mechanisms.

Abstract
Background: Prostatitis-like symptoms (PLS) lead to severe discomfort in males in their daily lives. Diet has been established as affecting PLS in our prior study, but the effect of nutrients, particularly for micronutrients remains largely unclear. Methods: This study enrolled 1284 participants from August 2020 to March 2021. The National Institute of Health−Chronic Prostatitis Symptom Index was used to assess PLS. The diet composition was evaluated by the Chinese Food Composition Tables. Results: Participants were separated into PLS (n = 216), control (n = 432), and noninflammatory-abnormal symptoms (NIANS) (n = 608) groups. We observed higher levels of carotene, vitamin C, vitamin E-(β+γ) and subclass, zinc, magnesium, selenium, potassium, sodium, iron and manganese in the PLS group than in the control group. After adjustment for the potential confounders, the elevated risk from IQR2 to IQR4 of fat (P for trend = 0.011), vitamin E-(β+γ) (P for trend = 0.003), magnesium (P for trend = 0.004), sodium (P for trend = 0.001) and copper (P for trend < 0.001) was identified. Conclusions: This is the first study to evaluate the nutrient distribution in PLS patients and reveal that the higher intake of fat, vitamin E-(β+γ), magnesium, sodium, and copper is associated with a risk of PLS.

CXCR3 antagonist AMG487 ameliorates experimental autoimmune prostatitis by diminishing Th1 cell differentiation and inhibiting macrophage M1 phenotypic activation. Prostate 2022; 82:1223-1236. [PMID: 35700340 DOI: 10.1002/pros.24395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Revised: 04/16/2022] [Accepted: 05/16/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) is an inflammatory immune disease that is characterized by infiltrating inflammatory cells in the prostate and pelvic or by perineal pain. Receptor CXCR3modulates immune and inflammatory responses; however, the effects of CXCR3 antagonist AMG487 in the context of CP/CPPS are unknown. Therefore, we investigated the effect of AMG487 in experimental autoimmune prostatitis (EAP) mice and explored the potential functional mechanisms. METHODS The EAP model was induced by intradermally injecting a mixture of prostate antigens and complete Freund's adjuvant on Days 0 and 28. To evaluate the effect of AMG487 on EAP mice, treatment with AMG487 and vehicle solution was conducted for the indicated period. Then, procedures were performed, including behavioral test, to evaluate the pain response to stimulation before the mice were killed and a histological assessment to evaluate the inflammation after the mice were killed. Immunofluorescence, flow cytometry, and Western blot assay were used to analyze the functional phenotype and regulation mechanism of AMG487 on T helper type 1 (Th1) cells and macrophages. RESULTS We found high expression of CXCR3 in human benign prostate tissues with inflammation and EAP mice. The elevated CXCR3 in prostate tissues correlates with the severity of inflammation. CXCR3 antagonist AMG487 treatment ameliorated the inflammatory changes and the pelvic pain of EAP mice. AMG487 inhibits Th1 cell differentiation through the IL-12/STAT4pathway and inhibits pro-inflammatory M1 macrophages through the lipopolysaccharide/NF-κB p65signaling. AMG487 could inhibit the secretion of inflammatory mediators in EAP mice. CONCLUSION CXCR3 antagonist AMG487 could ameliorate the inflammatory changes and the pelvic pain of EAP mice by diminishing Th1 cell differentiation and inhibiting macrophage M1 phenotypic activation. Thus, the results imply that AMG487 has the potential as an effective therapeutic agent in the prevention and treatment of EAP.

Abstract
Objective Low-intensity shockwave therapy (LiST) has been applied in the clinical treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), but few studies have focused on the prediction of its therapeutic effect before treatment. Methods Seventy-five CP/CPPS patients from our institute between July 2020 and May 2021 were enrolled and received 3 Hz, 0.25 mJ/mm2 LiST once a week over the course of four weeks. The scores of the NIH-CPSI, IPSS questionnaire and demographic features before treatment were recorded. The plasma before LiST treatment was also collected, while liquid chromatography-tandem mass spectrometry was used to detect the metabolites. Least absolute shrinkage and selection operator (LASSO) regression analysis was employed to identify the prediction metabolites and generate the metabolism score. Receiver operating characteristic curves and calibration curves were drawn to assess the prediction accuracy of the nomogram. Results Twelve metabolites were identified at incomparable levels before and after LiST treatment. The metabolism score generated by LASSO analysis presented a perfect prediction value (AUC: 0.848, 95% CI: 0.719-0.940) in the training cohort and further increased to 0.892 (95% CI: 0.802-0.983) on the nomogram, which accompanied with the NIH-CPSI scores and age. Similar results of the metabolism score (AUC: 0.732, 95% CI: 0.516-0.889) and total nomogram (AUC: 0.968, 95% CI: 0.909-1.000) were obtained in the testing cohort. Further enrichment of the 12 metabolites indicated that the glycine and serine metabolism pathway was involved in the LiST treatment. Conclusion We used our system to accurately and quantitatively measure plasma metabolites and establish a predictive model to identify suitable patients for LiST treatment.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a poorly understood disease. Accumulating evidence suggests that autoimmune dysfunction is involved in the development of CP/CPPS. Interleukin-17 (IL-17) is associated with the occurrence and development of several chronic autoimmune inflammatory diseases. However, the molecular mechanisms underlying the role of IL-17 in CP/CPPS are not clear. We confirmed that IL-17 was increased in the prostate tissues of experimental autoimmune prostatitis (EAP) mice. Corresponding to the increase of IL-17, neutrophil infiltration and the levels of CXCL1 and CXCL2 (CXC chemokine ligands 1 and 2) were also increased in the prostate of EAP. Treatment of EAP mice with an IL-17-neutralizing monoclonal antibody (mAb) decreased the number of infiltrated neutrophils and CXCL1 and CXCL2 levels. Depletion of neutrophils using anti-Ly6G antibodies ameliorated the inflammatory changes and hyperalgesia caused by EAP. Fucoidan, a could potent inhibitor of neutrophil migration, also ameliorate the manifestations of EAP. Our findings suggested that IL-17 promoted the production of CXCL1 and CXCL2, which triggered neutrophil chemotaxis to prostate tissues. Fucoidan might be a potential drug for the treatment of EAP via the effective inhibition of neutrophil infiltration.

Abstract
Objective UPOINT clinical phenotype system was used to estimate the type III prostatitis patients. Put in the erectile dysfunction (ED) domain and analysis the ED domain's effect towards the UPOINT system. Methods A total of 126 patients with type III prostatitis were prospectively collected and classified in each domain of the UPOINT system, including urinary, psychosocial, organ-specific, infection, neurological/systemic, and tenderness. Symptom severity was measured using the national institutes of health chronic prostatitis symptom index (NIH-CPSI) and the international prostate symptom score (IPSS). The erectile function was evaluated using the international index of erectile function (IIEF-5). Mental state was evaluated using the Symptom Checklist 90 (SCL-90). The quality of life of patients was assessed by the Quality of Life scale (QoL). Results The percentage of patients positive for each domain was 60.32%, 43.65%, 53.17%, 11.11%, 42.06%, and 33.33% for the urinary, psychosocial, organ-specific, infection, neurological/systemic, and tenderness, respectively. There were significant correlations between the number of positive UPOINT domains and total NIH-CPSI (r = 0.630, P < 0.001) and IPSS (r = 0.429, P < 0.001). Symptom duration was associated with a number of positive domains (r = 0.194, P < 0.05). After adding an ED domain to establish a modified UPOINT system, the correlation between the number of positive domains and symptom severity was not improved (0.630 to 0.590, P < 0.001). The percentage of the patients who suffered psychosocial problems was 43.65%. Conclusions In our cohort, the number of positive domains was correlated with symptom severity. Inclusion of the ED phenotype in the UPOINT phenotype classification system did not significantly enhance the association of positive presentation with symptom severity. Our findings presented do not support the utility of using ED as a stand-alone item in the UPOINT domain. Psychological problems should be considered when treating type III prostatitis patients.

Abstract
Background Chronic nonbacterial prostatitis (CNP) has a high incidence, low cure rate, and unclear pathogenesis. Here, we aimed to systematically identify effective diagnostic and therapeutic targets for CNP. Methods Prostate tissues were obtained from established mouse models and negative controls and were used for mRNA array sequencing and immunohistochemistry (IHC) staining. Predominant pathways were identified based on pathway enrichment analysis and pharmaceutical experiments. We also investigated the functional role of CXCL12 on CP, a critical factor belonging to the predominant chemotaxis pathway, and employed IHC staining to explore the influence of the CXCL12/CXCR4 axis on the activation of the NF-κB, AKT, and STAT3 signaling pathways. Serum samples derived from both CNP cases and healthy controls were used to determine the secretion level of CXCL12. Results By employing mRNA array sequencing and immunohistochemistry, we found that CXCR4, CXCL12, CD44, and OFLM4 were highly expressed in the infiltrated inflammatory T cells of the prostate tissues generated from CNP mice, while they were rarely expressed on the epithelial cells. Based on the pathway enrichment results, we applied pathway inhibitors to suppress the activity of these classic pathways. We found that targeting the CXCL12/CXCR4 axis with its specific antagonist AMD3100 remarkably alleviated inflammatory infiltration of the prostate in CNP models. Similar results were obtained when we replaced AMD3100 with adenovirus-associated virus (AAV)-shCxcl12. To clarify the potential mechanisms of how the CXCL12/CXCR4 axis influences the pathogenesis of CNP, we tested the classical downstream pathways. The results suggested that p-Akt, p-STAT3, and p-NF-κB were more highly expressed on the inflammatory cells of the prostate derived from the CNP model and were partly suppressed after applying AMD3100 or delivering AAV-shCxcl12, indicating that the CXCL12/CXCR4 axis potentially functioned through AKT/NF-κB and STAT3 signaling to influence the pathogenesis of CNP. Conclusion Our study provides potential diagnostic biomarkers and therapeutic targets for CNP.

Abstract
Urogenital inflammation is a known cause of male infertility. Increased levels of inflammatory cytokines, leukocyte counts and oxidative stress are highly detrimental for sperm quality thus compromising male fertility. Although cytokines affect sperm by recruiting and activating leukocytes consequently inducing tissue inflammation and oxidative stress, scarce to absent data have been reported about the putative direct effects of inflammatory cytokines on spermatozoa. Herein, we analyzed whether IFNγ, IL-17A, IL-1β, and IL-8 can alter human sperm motility and viability per se. Fractions of viable and motile spermatozoa from normospermic healthy donors were in vitro incubated with recombinant human IFNγ, IL-17A, IL-1β or IL-8 and sperm ROS production, motility, viability and apoptosis were analyzed. Sperm exposed to different concentrations of IFNγ, IL-17A and IL-1β, or a combination of them, for either 1 or 3 h showed significantly increased levels of mitochondrial ROS production and reduced motility and viability with respect to sperm incubated with vehicle. Moreover, the exposure to IFNγ, IL-17A and IL-1β resulted in significantly higher levels of early and/or late apoptotic and/or necrotic spermatozoa. Interestingly, no significant differences in sperm motility, viability and apoptosis were observed in sperm incubated with the concentrations of IL-8 analyzed, for either 1 or 3 h, with respect to sperm incubated with vehicle. In conclusion, our results indicate that IFNγ, IL-17A and IL-1β per se impair sperm motility and decreases viability by triggering increased mitochondrial ROS production and inducing sperm apoptosis. Our results suggest that screening inflammatory cytokines in semen would be an additional helpful tool for the diagnostic workup of male infertility.

Abstract
BACKGROUND Prostatitis is the third most common urologic condition affecting more than half the male population at some point in their lives. There are different categories of prostatitis, of which approximately 90% of cases can be classified under the National Institute of Health (NIH) type III category (chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS)) with no causative agents identified. CP/CPPS is associated with several symptoms, of which the most prominent being chronic pain. Despite its high incidence, pain management in patients with CP/CPPS has been poor, possibly due to the lack of understanding of aetiological factors and mechanisms underlying pain development. METHODS An extensive literature search of published articles on the molecular mechanisms of pain in CP/CPPS was conducted using PubMed and Google Scholar search engines (https://pubmed.ncbi.nlm.nih.gov and https://scholar.google.com). The terms used for the search were: prostatitis, pain mechanism in CP/CPPS, prostatitis pain models, acid-sensing ion channels (ASICs), transient receptor potential vanilloid type 1 (TRPVs), purinergic channels (P2X) in prostatitis pain mechanism and inflammatory mediators in CP/CPPS. The papers were identified based on the title and abstract, and after excluding the articles that did not emphasize the pain mechanism in CP/CPPS. Ninety-five articles (36 review and 59 original research papers) met our criteria and were included in the review. RESULTS A number of inflammatory mediator molecules and pain channels, including ASICs, transient receptor potential vanilloid channels (TRPVs) and P2Xs have been investigated for their role in prostatitis pain pathology using various animal models. CONCLUSION This review summarizes the pain mechanisms in CP/CPPS focusing on the inflammatory mediators, neurotransmitters, pain-transducing ion channels and small animal models developed for studying prostatitis.

Abstract
Chronic prostatitis/Chronic pelvic pain syndrome (CP/CPPS) is a condition that affects a large number of men and has unknown etiology. We have previously demonstrated the presence of elevated levels of mast cell tryptase in expressed prostatic secretions (EPS) of CP/CPPS patients. In a murine model of CP/CPPS, we showed tryptase and its cognate receptor PAR2 as critical to the development of pelvic pain and lower urinary tract symptoms. Here, we extend these observations to demonstrate that an isoform of tryptase called delta (δ)-tryptase, is elevated in the EPS of patients with CP/CPPS and is correlated with pelvic pain symptoms. Using an Escherichia coli (CP1) -induced murine model of CP/CPPS, we demonstrated a differential response in C57BL/6J and NOD/ShiLtJ mice, with C57BL6/J mice being resistant to an increase in pelvic tactile allodynia, despite having equivalent levels of activated mast cells in the prostate. Activated tryptase+ve mast cells were observed to be in closer apposition to PGP9.5+ve nerve fibers in the prostate stroma of NOD/ShiLtJ in comparison to C57BL/6J mice. The mouse ortholog of δ-tryptase, mouse mast cell protease 7 (mMCP7) has been reported to be unexpressed in C57BL/6J mice. We confirmed the absence of mMCP7 in the prostates of C57BL/6J and its presence in NOD/ShiLtJ mice. To evaluate a role for mMCP7 in the differential allodynia responses, we performed direct intra-urethral instillations of mMCP7 and the beta (β)-tryptase isoform ortholog, mMCP6 in the CP1-infection model. mMCP7, but not mMCP6 was able to induce an acute pelvic allodynia response in C57BL/6J mice. In-vitro studies with mMCP7 on cultured mast cells as well as dissociated primary neurons demonstrated the ability to induce differential activation of pain and inflammation associated molecules compared to mMCP6. We conclude that mMCP7, and possibility its human ortholog δ-tryptase, may play an important role in mediating the development of pelvic tactile allodynia in the mouse model of pelvic pain and in patients with CP/CPPS.

Abstract
A 10-year-old, male intact, mixed breed dog was admitted with a history of intermittent lower urinary tract signs of eighteen-months duration. Dysuria, stranguria, pollakiuria and overflow incontinence developed 2 weeks prior to presentation, while vomiting, polydipsia and anorexia were seen a few days prior to admission. Physical examination revealed prostatomegaly. Biochemistry results were compatible with postrenal azotemia. Abdominal imaging confirmed prostatomegaly with consequent urethral obstruction, and ultrasound-guided fine needle aspiration cytology of the prostate gland was consistent with granulomatous inflammation. The dog was hospitalized, urethral patency was preserved and upon laparotomy a cystostomy tube was placed, and prostatic biopsy was obtained. Orchiectomy was also performed. Urine culture performed two days prior to the surgery was negative. Prostatic histopathology revealed mild to moderate lymphoplasmacytic prostatitis. Three months postoperatively, clinical signs had resolved completely and urinations remained normal while the dog is still in good health three years after diagnosis. This is the first case of canine lymphoplasmacytic prostatitis in which clinical signs, diagnostic evaluation, management and long-term follow up are available.

Abstract
Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) is an inflammatory immune disease characterized by intraprostatic leukocyte infiltration and pelvic or perineal pain. Macrophages play vital roles in the pathogenesis of CP/CPPS. However, the mechanisms controlling the activation and chemotaxis of macrophages in CP/CPPS remain unclear. This study aimed to investigate the roles of the CXCL10/CXCR3 pathway in the activation and chemotaxis of macrophages in CP/CPPS patients. The serums of CP/CPPS patients and healthy volunteers were collected and measured. Results showed that CXCL10 expression was significantly elevated and correlated with the severity of CP/CPPS patients. The experimental autoimmune prostatitis (EAP) model was generated, and adeno-associated virus and CXCR3 inhibitors were used to treat EAP mice. Immunofluorescence, flow cytometry, and Western blotting were used to analyze the functional phenotype and regulation mechanism of macrophages. Results showed that CXCL10 deficiency ameliorates EAP severity by inhibiting infiltration of macrophages to prostate. Moreover, CXCL10 could induce macrophage migrations and secretions of proinflammatory mediators via CXCR3, which consequently activated the downstream Erk1/2 and p38 MAPK signaling pathways. We also showed that prostatic stromal cell is a potential source of CXCL10. Our results indicated CXCL10 as an important mediator involved in inflammatory infiltration and pain symptoms of prostatitis by promoting the migration of macrophages and secretion of inflammatory mediators via CXCR3-mediated ERK and p38 MAPK activation.

IL-1β-primed mesenchymal stromal cells exert enhanced therapeutic effects to alleviate Chronic Prostatitis/Chronic Pelvic Pain Syndrome through systemic immunity. Stem Cell Res Ther 2021; 12:514.

Abstract
BACKGROUND Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) seriously affects patient health. Despite the elusiveness of innate therapeutic effects, mesenchymal stromal cells (MSCs) hold great promise for inflammation-related diseases. Recent evidence indicates that disease-specific inflammatory cytokines could enhance the therapeutic effects of MSCs. METHODS By establishing a CP/CPPS mouse model and pretreating MSCs with the cytokine interleukin-1β (IL-1β), we studied the IL-1β-primed MSC immunoregulatory ability and targeted migration ability in vitro and in CP/CPPS mice. RESULTS IL-1β levels significantly increased in the prostate tissue and serum of experimental autoimmune prostatitis (EAP) mice. Pretreatment with IL-1β enhanced the immunomodulatory potential and targeted migration of MSCs in vitro. Furthermore, intravenous infusion of IL-1β-primed MSCs dampened inflammation in prostate tissues and alleviated hyperalgesia in EAP mice. The infused MSCs inhibited monocyte infiltration and promoted regulatory T lymphocyte formation in prostate tissue, thus remodeling the local environment. Surprisingly, IL-1β-primed MSCs exhibited improved accumulation in the spleen but not in prostate tissue. Accordingly, infused MSCs reshaped systemic immunity by reducing the proportion of Ly6ChighCD11b+ monocytes and boosting the proportion of CD4+Foxp3+ regulatory T lymphocytes in the spleen and lung. Inflammatory chemokine (C-C motif) ligand 2 (CCL2) decreased through the downregulation of the NF-κB and JNK/MAPK pathways by inflammatory resolution via MSCs infusion to alleviate pain. CONCLUSION In summary, IL-1β-primed MSCs restored systemic immunologic homeostasis to alleviate CP/CPPS by modulating systemic immunity. These findings provide a novel strategy to boost the therapeutic effects of MSC-based therapy for CP/CPPS and reveal the essential role of systematic immunity in the treatment of CP/CPPS with MSC infusion.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), characterized by chronic pain in the perineum or lower abdomen regions, is a frequent disorder in men. Previous studies demonstrated that the immune mediators, including interleukin (IL)-1β, IL-6, interferon-γ, tumor necrosis factor-α, and immunoglobulins, are elevated in the expressed prostate secretions and seminal fluid of CP/CPPS men. The memory T, T helper 1 (Th1), Th17, and Th22 cells increase in the peripheral blood of CP/CPPS men. Additionally, prostate antigens specific-autoreactive T cells are identified in CP/CPPS patients. After generally reviewing and comparing the inflammatory responses in autoimmune diseases and CP/CPPS, we presumed that CP/CPPS is more likely to be defined as an autoimmune disease. Thus, a better understanding of autoimmune diseases would contribute to a deeper understanding of the CP/CPPS and provide new inspirations for the treatment of this disease.

Abstract
Purpose: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), affecting over 90% of patients with symptomatic prostatitis, remains a therapeutic challenge and adversely affects patients’ quality of life (QoL). This study probed for likely beneficial effects of ESWT, evaluating its extent and durability. Patients and methods: Standardized indices, namely the pain, urinary, and QoL domains and total score of NIH-CPSI, IIEF-5, EHS, IPSS, and AUA QoL_US were employed in this study of patients with CP/CPPS who had been refractory to other prior treatments (n = 215; age range: 32–82 years; median age: 57.5 ± 12.4 years; modal age: 41 years). Results: For CP symptoms, the mean pre-ESWT NIH-CPSI total score of 27.1 ± 6.8 decreased by 31.3–53.6% over 12 months after ESWT. The mean pre-ESWT NIH-CPSI pain (12.5 ± 3.3), urinary (4.98 ± 2.7), and QoL (9.62 ± 2.1) domain scores improved by 2.3-fold, 2.2-fold, and 2.0-fold, respectively, by month 12 post-ESWT. Compared with the baseline IPSS of 13.9 ± 8.41, we recorded 27.1–50.9% amelioration of urinary symptoms during the 12 months post-ESWT. For erectile function, compared to pre-ESWT values, the IIEF-5 also improved by ~1.3-fold by month 12 after ESWT. This was corroborated by EHS of 3.11 ± 0.99, 3.37 ± 0.65, 3.42 ± 0.58, 3.75 ± 0.45, and 3.32 ± 0.85 at baseline, 1, 2, 6, and 12 months post-ESWT. Compared to the mean pre-ESWT QoL score (4.29 ± 1.54), the mean QoL values were 3.26 ± 1.93, 3.45 ± 2.34, 3.25 ± 1.69, and 2.6 ± 1.56 for months 1, 2, 6, and 12 after ESWT, respectively. Conclusions: This study shows ESWT, an outpatient and easy-to-perform, minimally invasive procedure, effectively alleviates pain, improves erectile function, and ameliorates quality of life in patients with refractory CP/CPPS.

Abstract
Experimental autoimmune prostatitis (EAP)-induced persistent inflammatory immune response can significantly upregulate the expression of N-methyl-D-aspartic acid (NMDA) receptors in the paraventricular nucleus (PVN). However, the mechanism has not yet been elucidated. Herein, we screened out the target prostate-derived inflammation cytokines (PDICs) by comparing the inflammatory cytokine levels in peripheral blood and cerebrospinal fluid (CSF) between EAP rats and their controls. After identifying the target PDIC, qualified males in initial copulatory behavior testing (CBT) were subjected to implanting tubes onto bilateral PVN. Next, they were randomly divided into four subgroups (EAP-1, EAP-2, Control-1, and Control-2). After 1-week recovery, EAP-1 rats were microinjected with the target PDIC inhibitor, Control-1 rats were microinjected with the target PDIC, while the EAP-2 and Control-2 subgroups were only treated with the same amount of artificial CSF (aCSF). Results showed that only interleukin-1β (IL-1β) had significantly increased mRNA-expression in the prostate of EAP rats compared to the controls (P < 0.001) and significantly higher protein concentrations in both the serum (P = 0.001) and CSF (P < 0.001) of the EAP groups compared to the Control groups. Therefore, IL-1β was identified as the target PDIC which crosses the blood-brain barrier, thereby influencing the central nervous system. Moreover, the EAP-1 subgroup displayed a gradually prolonged ejaculation latency (EL) in the last three CBTs (all P < 0.01) and a significantly lower expression of NMDA NR1 subunit in the PVN (P = 0.043) compared to the respective control groups after a 10-day central administration of IL-1β inhibitors. However, the Control-1 subgroup showed a gradually shortened EL (P < 0.01) and a significantly higher NR1 expression (P = 0.004) after homochronous IL-1β administration. Therefore, we identified IL-1β as the primary PDIC which shortens EL in EAP rats. However, further studies should be conducted to elucidate the specific molecular mechanisms through which IL-1β upregulates NMDA expression.

Comparing two different low-intensity shockwave therapy frequency protocols for nonbacterial chronic prostatitis/chronic pelvic pain syndrome: A two-arm, parallel-group randomized controlled trial. Prostate 2021; 81:499-507.

Abstract
BACKGROUND Despite encouraging results, the optimal low-intensity shockwave therapy (LiST) protocol in patients with chronic prostatitis/chronic pelvic pain syndrome (CPPS) remains unknown. We conducted a two-arm, parallel-group, randomized controlled trial aiming to compare the efficacy and safety of six LiST sessions applied once or twice weekly. METHODS Fifty patients with CP/CPPS type IIIb were randomly assigned to six LiST sessions once (Group A, n = 25) or twice weekly (Group B, n = 25). Both groups followed the same treatment protocol in terms of LiST application, impulses (5000/session), energy flux density (0.096 mJ/mm2 ) and frequency (5 Hz). Subsequently, all participants were evaluated at 1 and 3 months after completion of LiST protocol. RESULTS At the follow-up evaluations, LiST significantly improved the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) total, pain and quality of life scores, as well as the International Index of Erectile Function-Erectile Domain (IIEF-ED) in both groups (p < .001 for all measures). Comparing between the two groups, no significant differences were demonstrated in the NIH-CPSI total, pain, urinary and quality of life scores, as well as in the International Prostate Symptom Score, IIEF-ED, and LiST-induced pain at both follow-up evaluations. Accordingly, no adverse events and no dropouts were observed in both groups. CONCLUSION Six sessions of LiST applied once weekly for 6 weeks or twice weekly for 3 weeks seem to be equally safe and effective in patients with CP/CPPS. Nevertheless, further studies are necessary, since LiST gradually gains its place for the management of CP/CPPS.

Abstract
BACKGROUND Due to limited data on the pathogenesis of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and the suboptimal therapeutic effect, the development of new and effective treatment modalities was needed urgently. Low-intensity extracorporeal shock wave therapy (Li-ESWT) has been reported for the treatment of CP/CPPS. However, the underlying mechanism remains to be elucidated. OBJECTIVE To interrogated the efficacy and the mechanism of Li-ESWT in the treatment of CP/CPPS. MATERIALS AND METHODS According to different treatments, RWPE-1 cells (human prostate epithelial cells) were randomly divided into three groups: control group, LPS(lipopolysaccharide) group, or Li-ESWT group (LPS induced RWPE-1 managed by Li-ESWT). Following the Li-ESWT treatment, the levels of oxidative stress was assayed. We then established a rat model of experimental autoimmune prostatitis (EAP) by injecting prostatic protein homogenate mixed with complete Freund's adjuvant. The Sprague-Dawley rats were randomly divided into the control group, EAP group, or Li-ESWT group. Von Frey Filament was used to quantify pelvic hyperalgesia in the rats. Prostates tissues from each group were collected for immunohistochemistry, oxidation stress, and western blot analysis. RESULTS Histological analysis showed reduced inflammation and expression of cytokines (TNF-α, IL-1β, IL-6, COX-2, SP) in prostate tissues from the Li-ESWT group compared with those from the EAP group (all P < 0.05). Similarly, there was reduced pelvic pain and allergic symptoms in the Li-ESWT group compared with the EAP group (all P < 0.05). Besides, Li-ESWT treatment could decrease oxidative stress in the prostate and in RWPE-1 cells, respectively (both P < 0.05). Moreover, the Li-ESWT up-regulated the expression of CAT through the inhibition of phosphorylation of AKT/FOXO1 signaling pathway. DISCUSSION AND CONCLUSIONS Li-ESWT may reduce inflammation, oxidative stress and pain in rats with autoimmunity-induced prostatitis via the PI3K/AKT/FOXO1 pathway. It implies that Li-ESWT can present a potential therapeutic option for the treatment of CP/CPPS.

Abstract
Three major pathogenic states of the prostate, including benign prostatic hyperplasia, prostate cancer, and prostatitis, are related to the local inflammation. However, the mechanisms underlying the initiation of prostate inflammation remain largely unknown. Given that the innate immune responses of the tissue-specific cells to microbial infection or autoantigens contribute to local inflammation, this study focused on pattern recognition receptor (PRR)-initiated innate immune responses in mouse prostatic epithelial cells (PECs). Primary mouse PECs abundantly expressed Toll-like receptor 3 (TLR3), TLR4, TLR5, melanoma differentiation-associated protein 5 (MDA5), and IFN-inducible protein 16 (p204 in mouse). These PRRs can be activated by their respective ligands: lipopolysaccharide (LPS) and flagellin of Gram-negative bacteria for TLR4 and TLR5, polyinosinic-polycytidylic acid (poly(I:C)) for TLR3 and MDA5, and herpes simplex virus DNA analog (HSV60) for p204. LPS and flagellin predominantly induced the expression of inflammatory cytokines, including tumor necrosis factor alpha (TNFA), interleukin 6 (IL6), chemokines monocyte chemoattractant protein-1 (MCP1), and C-X-C motif chemokine 10 (CXCL10). Poly(I:C) and HSV60 predominantly induced the expression of type 1 interferons (IFNA and IFNB) and antiviral proteins: Mx GTPase 1, 2',5'-oligoadenylate synthetase 1, and IFN-stimulated gene 15. The replication of mumps virus in PECs was inhibited by type 1 IFN signaling. These findings provide insights into the mechanisms underlying innate immune response in the prostate.

[PMID: 33743834 PMCID: PMC7981875 DOI: 10.1186/s13287-021-02269-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Accepted: 03/05/2021] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is an intractable nonbacterial inflammatory disease. Mesenchymal stem cells (MSCs) derived from human induced pluripotent stem cells (hiPSCs, iMSCs) have been well documented for the management of inflammatory and autoimmune disorders because of their powerful immunoregulatory and anti-inflammatory capacities. Recently, studies have indicated that extracellular vesicles (EVs) released from iMSCs hold biological functions similar to their parental cells. This study aimed to evaluate the therapeutic efficacy of EVs released from iMSCs (iMSCs-EVs) on CP/CPPS and to explore the underlying mechanisms. METHODS An experimental autoimmune prostatitis (EAP) model was established in rats by subcutaneous injection of prostate antigen with adjuvant. Then, iMSCs-EVs were injected into EAP rats via the tail vein. Pain behavioral measurements, urodynamic tests, and histopathological analyses were performed at 2, 4, and 6 weeks. The expression of cyclooxygenase-2 (COX-2) was evaluated by immunofluorescence staining and Western blot. The alterations of B cells, Th1 cells, Th2 cells, Th17 cells, and Treg cells in peripheral blood and spleen were analyzed using flow cytometry. The levels of Th1-, Th2-, Th17-, and Treg-related inflammatory mediators were determined by ELISA. RESULTS After iMSCs-EVs administration, rats had reduced pain as indicated by the recovery of nociceptive responses to baseline. The voiding pressure was significantly reduced, and the intercontraction interval was increased. The findings of histopathological analysis revealed that iMSCs-EVs could significantly decrease inflammatory cell infiltration and promote basal lamina and glandular epithelial tissue repair. Further studies demonstrated that the overexpression of COX-2 was downregulated by iMSCs-EVs. Meanwhile, the increases in the percentages of Th1 and Th17 cells were dramatically reversed. Also, rats that received iMSCs-EVs showed markedly increased percentages of Treg cells. The levels of those inflammatory mediators showed the same changing tendency. CONCLUSIONS iMSCs-EVs administration has the potential to ameliorate chronic pelvic pain, improve voiding dysfunction, suppress inflammatory reactions, and facilitate prostatic tissue repair. The functions are mediated by downregulating the overexpression of COX-2 and restoring the imbalance of Th1/Th2 and Treg/Th17 cells.

Experimental Chronic Prostatitis/Chronic Pelvic Pain Syndrome Increases Anxiety-Like Behavior: The Role of Brain Oxidative Stress, Serum Corticosterone, and Hippocampal Parvalbumin-Positive Interneurons. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:6687493. [PMID: 33815658 PMCID: PMC7990537 DOI: 10.1155/2021/6687493] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Revised: 02/08/2021] [Accepted: 02/10/2021] [Indexed: 12/21/2022]
Abstract
Mechanisms of the brain-related comorbidities in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) are still largely unknown, although CP/CPPS is one of the major urological problems in middle-aged men, while these neuropsychological incapacities considerably diminish life quality. The objectives of this study were to assess behavioral patterns in rats with CP/CPPS and to determine whether these patterns depend on alterations in the brain oxidative stress, corticosterone, and hippocampal parvalbumin-positive (PV+) interneurons. Adult male Wistar albino rats from CP/CPPS (intraprostatic injection of 3% λ-carrageenan, day 0) and sham (0.9% NaCl) groups were subjected to pain and anxiety-like behavior tests (days 2, 3, and 7). Afterwards, rats were sacrificed and biochemical and immunohistochemical analyses were performed. Scrotal allodynia and prostatitis were proven in CP/CPPS, but not in sham rats. Ethological tests (open field, elevated plus maze, and light/dark tests) revealed significantly increased anxiety-like behavior in rats with CP/CPPS comparing to their sham-operated mates starting from day 3, and there were significant intercorrelations among parameters of these tests. Increased oxidative stress in the hippocampus, thalamus, and cerebral cortex, as well as increased serum corticosterone levels and decreased number of hippocampal PV+ neurons, was shown in CP/CPPS rats, compared to sham rats. Increased anxiety-like behavior in CP/CPPS rats was significantly correlated with these brain biochemical and hippocampal immunohistochemical alterations. Therefore, the potential mechanisms of observed behavioral alterations in CP/CPPS rats could be the result of an interplay between increased brain oxidative stress, elevated serum corticosterone level, and loss of hippocampal PV+ interneurons.

Immunological alterations in patients with chronic prostatitis/chronic pelvic pain syndrome and experimental autoimmune prostatitis model: A systematic review and meta-analysis. Cytokine 2021; 141:155440. [PMID: 33550164 DOI: 10.1016/j.cyto.2021.155440] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Revised: 11/28/2020] [Accepted: 12/23/2020] [Indexed: 12/24/2022]
Abstract
BACKGROUND As one of the most common conditions in urological outpatients, chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) puzzles many individuals because of its unclear etiology and lack of effective treatment. Recently, immunological alterations underpinning CP/CPPS have been extensively investigated. METHODS The PubMed, Web of Science, Cochrane library, and EMBASE databases were used to search original articles on immune mediators in patients with CP/CPPS and in experimental autoimmune prostatitis (EAP) models through April 10, 2020. Standardized mean differences (SMD) were calculated to summarize the differences in immune mediator levels between groups. Funnel plot, Begg's funnel plot, Egger's regression test, and the sensitivity analysis were applied to determine and visualize the stability of our findings. RESULTS A total of 34 original studies were included in the meta-analysis, including 24 studies on patients with CP/CPPS and 10 studies on EAP models. We found that TNF-α, IL-1β, IL-6, and IL-8 were the four immune mediators that elevated in most of the samples derived from patients with CP/CPPS and the EAP models. The adjusted publication bias analysis indicated that publication bias was not existed, and the sensitivity analyses showed that the results were stable. CONCLUSIONS Immune responses play significant roles during the pathogenesis of CP/CPPS by promoting intraprostatic inflammation. Our findings provide potential diagnostic and therapeutic targets for CP/CPPS patients.

Abstract
OBJECTIVE To validate the efficacy and safety of Ningmitai capsule (NMT) in the patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). METHODS We conducted a multicenter, randomized, double-blind, placebo-controlled trial in 120 men with CP/CPPS to evaluate the efficacy and safety of NMT. Participants were randomly assigned (1:1) to NMT or placebo treatment for 4 weeks at 3 centres. The patients were evaluated by the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) at baseline, the end of 2 and 4 weeks of treatment. The primary endpoints were the changes of the NIH-CPSI pain scores from baseline to the end of 2 and 4 weeks of the treatment. The secondary endpoints include the changes of the NIH-CPSI total scores, urinary symptoms scores and the quality of life (QoL) as well as the responder rate. RESULTS After 2 and 4 weeks of treatment, the mean decreases of the NIH-CPSI pain scores, total scores and QoL in the NMT group were all significantly superior to those in the placebo group. The responder rate was significantly higher in the NMT group than that in the placebo group at both 2 and 4 weeks. No adverse events were reported during the treatment. CONCLUSION NMT could significantly improve the pain symptoms and QoL in the patients with CP/CPPS as early as in 2 weeks, and the efficacy enhanced at the end of the 4-week treatment. The safety of NMT was confirmed in this trial.

Abstract
We performed a complex morphological study of biopsy samples of prostate gland from 30 men (mean age 46±11 years) with chronic abacterial prostatitis who were exposed unfavorable anthropogenic factors. The ultrastructural heterogeneity of smooth muscle cells was shown, among which cells with destructive changes in organelles predominated, solitary cells with signs of secretory function were revealed. Most endothelial cells in microvessels were characterized by low pinocytotic activity, destruction of organelles; focal hyperplastic ultrastructural changes were noted in some endotheliocytes. Along with fibroblasts, the stroma contained single mast cells; no inflammatory infiltration was revealed. The results of the study attested to complex mechanisms of remodeling of the prostate gland stroma in chronic abacterial prostatitis involving microvessels, smooth muscle cells, and probably mast cells, which determines the development of degenerative, destructive, and fibrotic processes.

Abstract
BACKGROUND Estimated 30%-40% of patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) suffer from premature ejaculation (PE), which is difficult to cure, but the mechanism is still unknown. Based on the results of our previous clinical studies and animal experiments, we propose that the glutamatergic system dysfunction in the paraventricular nucleus (PVN) may be involved. METHODS To test this hypothesis, we used experimental autoimmune prostatitis (EAP) rats to investigate the effects of CP/CPPS on ejaculation behavior through integrating copulatory behavior testing, neuroelectrophysiologic experiments, and molecular biology technologies. RESULTS Histological examination of prostate tissue in EAP rats exhibited consistent pathological findings with that in CP/CPPS patients. Behavior testing showed that ejaculation latency (EL) of EAP rats significantly shortened compared with the controls (5.1 ± 1.8 vs 9.1 ± 2.4 min, P < .001). Sympathetic nervous system (SNS) activity testing revealed that EAP rats displayed significantly higher plasma norepinephrine (NE) level (1780 ± 493 vs 1421 ± 453 pg/mL, P = .043) and SNS sensitivity (67.8 ± 9.6 vs 44.6 ± 8.7%, P < .001). Immunohistochemical detection and Western blot analysis both displayed that NR1 subunit expression of N-methyl-D-aspartic acid (NMDA) receptors in the PVN of EAP rats was significantly upregulated (P = .007 and P < .001). Furthermore, the expression of NMDA NR1 subunit positively correlated both with SNS sensitivity (r = .917, P < .001) and prostatic inflammation scores (r = .964, P < .001). CONCLUSION This study shows that EAP rats suffer from the same PE symptom as CP/CPPS patients. CP/CPPS-induced inflammatory-immune response can significantly upregulate the expression of NMDA receptors in the PVN, which shortening the EL by enhancing SNS sensitivity. However, the exact mechanism of chronic inflammation in the prostate causing the upregulated expression of NMDA receptors needs to be further studied.

Abstract
BACKGROUND Chronic prostatitis or chronic pelvic pain syndrome (CP/CPPS) is a disease with an unclear pathogenesis. Recent studies have reported that regulatory T (Treg) cells might be involved in the development of CP/CPPS. In this study we aimed to examine the functional role of Treg cells and explore the possible regulatory mechanism of Treg cells in CP/CPPS. METHODS An experimental autoimmune prostatitis (EAP) mouse model was constructed; the numbers and functions of Treg cells in the EAP and control groups were tested. Then, cell differentiation experiments were conducted to evaluate the regulatory effect of autophagy on Treg cell differentiation. Furthermore, autologous CD4+ CD25- cells and CD4+ CD25+ cells from the two groups were magnetically sorted and cocultured to observe differences in cellular inhibitory functions. Finally, in an in vivo experiment, rapamycin was intraperitoneally injected into EAP mice for 4 weeks to observe the therapeutic effects. RESULTS We found that the number and function of Treg cells in the EAP group were diminished compared to those in the control group. Meanwhile, the tolerance of pain in EAP mice had also decreased. Moreover, after using the autophagy activator rapamycin, the expression of the inflammatory cytokines interleukin-1β was decreased and the pain symptoms were alleviated. A mechanistic study found that autophagy activation promoted the differentiation of Treg and increased the suppressive functions of Treg cells, along with the elevated expression of GATA-3 and cytotoxic T lymphocyte antigen 4 (CTLA-4). Furthermore, in vivo administration of the autophagy activator rapamycin had similar effects on recovering the frequency and function of Treg cells as well as the expression of GATA-3 and CTLA-4. CONCLUSION The impaired frequency and function of Treg cells may contribute to the progression of CP/CPPS, and autophagy is a protective mechanism that promotes the differentiation of Treg cells and restores the suppressive functions of Treg cells. Autophagy may be a novel therapeutic option for patients with CP/CPPS.

Abstract
Corydalis Rhizoma (CR) is a commonly used traditional Chinese medicine for its potency in activating blood circulation and analgesia. In clinic, CR extracts or components are commonly used in the treatment of myocardial ischemia, rheumatism, and dysmenorrhea with different types of inflammation. However, due to different mechanism of pain and inflammation, the anti-inflammatory property of CR has not been fully revealed. Here, the major chromatographic peaks of CR extracts in different extracting solvents were identified, and the anti-inflammatory activities of CR extracts and its major alkaloids were evaluated in LPS-treated macrophages by determining expressions of proinflammatory cytokines, IκBα and NF-κB. The most abundant alkaloid in CR extract was dehydrocorydaline, having >50% of total alkaloids. Besides, the anti-inflammatory activities of dehydrocorydaline and its related analogues were demonstrated. The anti-inflammatory roles were revealed in LPS-treated cultured macrophages, including (i) inhibiting proinflammatory cytokines release, for example, TNF-α, IL-6; (ii) suppressing mRNA expressions of proinflammatory cytokines; (iii) promoting IκBα expression and suppressing activation of NF-κB transcriptional element; and (iv) reducing the nuclear translocation of NF-κB. The results supported that dehydrocorydaline was the major alkaloid in CR extract, which, together with its analogous, accounted the anti-inflammatory property of CR.

Abstract
Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) is a complicated syndrome characterized by genitourinary pain in the absence of bacterial infection. Th17 cell-driven autoimmunity has been proposed as a cause of CP/CPPS. However, the factors that promote Th17-driven autoimmunity in experimental autoimmune prostatitis (EAP) and the molecular mechanisms are still largely unknown. Here, we showed that Th17 cells were excessively activated, and blockade of IL-17A could effectively ameliorate various symptoms in EAP. Furthermore, we revealed that calcium/calmodulin-dependent kinase Ⅳ (CaMK4), especially Thr196 p-CaMK4 was increased in the Th17 cells of the EAP group, which were activated by intracellular cytosolic Ca2+ . Pharmacologic and genetic inhibition of CaMK4 decreased the proportion of Th17 cells, and the protein and mRNA level of IL-17A, IL-22, and RORγt. The phosphorylation of CaMK4 was dependent on the increase in intracellular cytosolic Ca2+ concentration in Th17 cells. A mechanistic study demonstrated that inhibition of CaMK4 reduced IL-17A production by decreasing the phosphorylation of Akt-mTOR, which was well accepted to positively regulate Th17 differentiation. Collectively, our results demonstrated that Ca2+ -CaMK4-Akt/mTOR-IL-17A axis inhibition may serve as a promising therapeutic strategy for CP/CPPS.

Abstract
Background Chronic prostatitis (CP) or chronic pelvic pain syndrome (CPPS) is one of the most common diseases in young and middle-aged men, accounting for 30% of outpatient men in urology OPD. There are no definitive diagnostic criteria for CP or CPPS and no accepted therapies that cure the disease. Methods We identified 372 patients with CP diagnosed from 2015 to 2018 and collect the information of age, routine urinary test, express prostatic secretion (EPS), and NIH-Chronic Prostatitis Symptom Index (NIH-CPSI). Results Our study proved a correlation between the increase of prostatic exosomal proteins (PSEPs) level and NIH-CPSI scores. Spearman’s correlation coefficient showed a significant level correlation between NIH-CPSI and PSEP level (rs=0.194, P=0.0035). In the meantime, the correlation was found between the PSEP level and EPS-white blood cells. Spearman’s correlation coefficient showed that there was a significant hierarchical correlation between EPS-white blood cells and PSEP level (rs=0.183, P=0.001). Conclusions These findings highlight the potential of PSEP is a practical indicator of the symptomatic progression of CP/CPPS. Applications of PSEP assay may guide drug discovery and lead to better treatment to improve the patient’s quality of life.All in all, PSEP detection in urine is safe and effective, and it is worthy of further promotion and application in clinical practice.

Influence of Experimental Autoimmune Prostatitis on Sexual Function and the Anti-inflammatory Efficacy of Celecoxib in a Rat Model. Front Immunol 2020; 11:574212.

Abstract
Experimental autoimmune prostatitis (EAP) is a well-established model induced by an autoimmune response to prostate antigen. The symptomatic, pathological, and immunological characteristics of EAP animals are highly consistent with human chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), which makes EAP an ideal model for this disease. Here, we investigate the influence of EAP on male rat sexual function and the efficacy of anti-inflammatory therapy with celecoxib. EAP rat models were established using male Wistar rats. Rats were randomly assigned to a normal control group, an EAP model group, or an EAP model with celecoxib treatment group (celecoxib group). Behavioral changes, sexual behavioral changes, and erectile function were estimated using an open-field test, a sucrose consumption test, mating experiments, and by intracavernous pressure/mean arterial pressure ratio (ICP/MAP). Histological changes in the prostate were observed by HE staining, and the serum inflammatory factors IL-1β and TNF-α levels were measured by enzyme-linked immunosorbent assay. In addition, serotonin (5-hydroxytryptamine, 5-HT), 5-HT1A receptor, 5-HT2C receptor, and serotonin transporter (SERT) expression levels in the hippocampus and spinal cord (T13–L1, L5–S2) were examined by immunohistochemistry and western blot analysis. Results showed that EAP rats exhibited characteristics of depression, decreased sexual drive, premature ejaculation, and increased threshold of penile erection. Moreover, all these changes were effectively alleviated by celecoxib. Significant increases in prostatic interstitial infiltration by inflammatory cells and in serum IL-1β and TNF-α levels were observed in EAP rats, and these were partially reduced by celecoxib. Additionally, the expression pattern of serotonin system regulators in the hippocampus and spinal cord were altered in EAP model rats, including a decrease in 5-HT levels and an increase in 5-HT1A receptor levels. In conclusion, autoimmune prostatitis impaired rat sexual function, and this was effectively prevented by anti-inflammatory therapy with celecoxib. Moreover, a serotonin system disorder in the central nervous system was likely mediated via inflammation in EAP rats.

Abstract
BACKGROUND Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is an intractable problem of the urogenital system. The aetiopathogenesis and effective treatments for CP/CPPS are needed to be untangled. Pirfenidone is a molecule that exhibits anti-inflammatory, antifibrotic, and antioxidative stress capacities in a variety of animal experiments and clinical trials. This study was aimed to investigate the therapeutic effect of pirfenidone on CP/CPPS and to identify the mechanism responsible for it. METHODS A CP/CPPS model was induced in rats by intraprostatic injection of complete Freund's adjuvant (CFA). Blood and prostatic tissues were harvested for assessment after the administration of pirfenidone or vehicle for 4 weeks. RESULTS The findings revealed that pirfenidone significantly ameliorated chronic pelvic pain and inhibited prostatic inflammation and fibrosis. Further study found that pirfenidone suppressed the expression of proinflammatory mediators, including tumor necrosis factor-α, interleukin-1β (IL-1β), IL-6, IL-8. Pirfenidone exhibited a potent antioxidant capacity through improving the activities of glutathione, catalase, total superoxide dismutase, and reducing the production of malondialdehyde. Furthermore, pirfenidone also facilitated the polarization of M2 macrophages and suppressed the activation of the nuclear factor-κB (NF-κB) signaling pathway. CONCLUSIONS Pirfenidone can exert a beneficial effect against CFA-induced CP/CPPS by anti-inflammatory, antioxidative, antifibrotic properties, and the function is mediated at least partly through the M2 polarization of macrophages and the inhibition of NF-κB signaling pathway. These findings suggest that pirfenidone holds promise as a potential therapeutic for the treatment of CP/CPPS.
