Int J Biol Macromol 2023; 249:126017. [PMID: 37517752 DOI: 10.1016/j.ijbiomac.2023.126017] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 06/23/2023] [Accepted: 07/25/2023] [Indexed: 08/01/2023]
Abstract
Anemarrhena asphodeloides polysaccharide (AAP70-1) was reported to have immunomodulatory effects in our previous report. To further improve the immunomodulatory effects of AAP70-1, an A. asphodeloides polysaccharide-zinc complex (AAP-Zn) was synthesized using a ZnCl2 modification method, and the potential mechanisms by which AAP-Zn activates macrophages were investigated. The results showed that the structural features of AAP-Zn were similar to those of AAP70-1 with a Zn content of 0.2 %, confirming that Zn mainly interacted with AAP70-1 by forming ZnO coordination bonds and Zn…OH bonds. In addition, the administration of AAP70-1 and AAP-Zn effectively improved the immunomodulatory effects by enhancing phagocytosis and upregulating the mRNA expression of cytokines (TNF-α, IL-6, IL-1β, and IL-18), as well as increasing the production levels of nitric oxide (NO) and reactive oxygen species (ROS) in zebrafish embryos. The intracellular mechanism by which AAP-Zn activates macrophages was found to involve activation of the NF-κB and MAPK signaling pathways. Our findings suggested that AAP-Zn may be a potential immunopotentiator in the field of biomedicine or functional foods.

Abstract
IntroductionHigh quality semen is essential for reproductive efficiency. Nutrition and environmental factors impact the ejaculate components, like cytokines, that are essential for pregnancy establishment. We hypothesized that differing nutritional periods and body condition scores would affect seminal plasma cytokine concentrations of bulls.MethodsMature Angus bulls (n=11) were individually housed and randomly assigned to either over-fed (n=5) or restricted (n=6) treatment pathways. Bulls were fed different volumes of a single ration creating 8 individual treatment periods. Body weight and body condition scores were taken every 14 d to manage intake volumes. Ejaculates were collected every 84 d to determine seminal plasma cytokine profiles. A complete randomized design was used to evaluate seminal plasma cytokines after each nutritional treatment. Initial cytokine concentrations and volume of the ejaculate were included as covariates.ResultsAll cytokines returned to initial concentrations following maintenance treatments at an ideal body condition score of 6. Nutritional treatments affected (P ≤ 0.05) IFN-γ, IL-8, MIP-1α, MIP-1β, TNF-α, IL-1β, and VEGF-A. However, TNF-α, IFN-γ, and MIP-1α had the greatest impact on cytokine profile.DiscussionNutritional levels and adiposity altered seminal plasma cytokine concentrations which could potentially impact the inflammatory balance of the uterus and the immune responses necessary for pregnancy establishment.

Abstract
Atopic dermatitis (AD), characterized by rashes, itching, and pruritus, is a chronic inflammatory condition of the skin with a marked infiltration of inflammatory cells into the lesion. It usually commences in early childhood and coexists with other atopic diseases such as allergic rhinitis, bronchial asthma, allergic conjunctivitis, etc. With a prevalence rate of 1–20% in adults and children worldwide, AD is gradually becoming a major health concern. Immunological aspects have been frequently focused on in the pathogenesis of AD, including the role of the epidermal barrier and the consequent abnormal cytokine expressions. Disrupted epidermal barriers, as well as allergic triggers (food allergy), contact allergens, irritants, microbes, aggravating factors, and ultraviolet light directly initiate the inflammatory response by inducing epidermal keratinocytes, resulting in the abnormal release of various pro-inflammatory mediators, inflammatory cytokines, and chemokines from keratinocytes. In addition, abnormal proteinases, gene mutations, or single nucleotide polymorphisms (SNP) affecting the function of the epidermal barrier can also contribute towards disease pathophysiology. Apart from this, imbalances in cholinergic or adrenergic responses in the epidermis or the role played by immune cells in the epidermis such as Langerhans cells or antigen-presenting cells can also aggravate pathophysiology. The dearth of specific biomarkers for proper diagnosis and the lack of a permanent cure for AD necessitate investigation in this area. In this context, the widespread role played by keratinocytes in the pathogenesis of AD will be reviewed in this article to facilitate the opening up of new avenues of treatment for AD.

Potential IFNγ Modulation of Inflammasome Pathway in Chlamydia trachomatis Infected Synovial Cells. Life (Basel) 2021; 11:life11121359.

Abstract
Following a Chlamydia trachomatis infection, the host immune response is characterized by its recognition via Toll-like and Nod-like Receptors, and the subsequent activation of interferon (IFN)-γ-mediated signaling pathways. Recently, the inflammasome-mediated host cell response has emerged to play a role in the physiopathology of C. trachomatis infection. Here we investigated, for the first time, the interaction of IFN-γ and inflammasome in an in vitro model of C. trachomatis-infected primary human synovial cells. Chlamydial replication as well as the expression of caspase-1, IL-1β, as well as IL-18 and IL-6, were assayed. Our results demonstrated the inhibitory activity of IFN-γ by interfering with the inflammasome network through the downregulation of caspase-1 mRNA expression. In addition, the ability of C. trachomatis to hinder the inflammasome pathway favoring its intracellular survival within synovial cells, was observed. Overall, our data suggest a potential mechanism of immune evasion by C. trachomatis in synovial cells, that may be contested by IFN-γ.

Abstract
HYPOTHESIS Autoimmune inner ear disease (AIED) patients will differentially express interleukin (IL)-6 based on corticosteroid responsiveness. BACKGROUND AIED is characterized by periods of acute sensorineural hearing loss (SNHL). In a majority of patients corticosteroid responsiveness is lost over time. The mechanisms that control corticosteroid responsiveness have not been fully elucidated. METHODS Thirty-five AIED patients and 13 age-matched control subjects were enrolled in this study. Steroid responsive (n = 15) and steroid nonresponsive AIED patients (n = 20) were characterized based on audiometry before and after treatment for acute SNHL. Plasma and peripheral blood mononuclear cells (PBMC) were obtained at the time of acute SNHL to quantify plasma IL-6, soluble IL-6 receptor (sIL-6R), and C-C Motif Chemokine Ligand 3 (CCL3). PBMCs were stimulated with dexamethasone and release of soluble IL-6, sIL-6R, and CCL3 protein into conditioned supernatants was measured. Plasma IL-6 was also correlated to serum c-reactive protein (CRP), cardiac CRP, erythrocyte sedimentation rate. RESULTS Statistically significant differences were observed in the plasma IL-6 between AIED patients and controls (2.37 versus 2.03 pg/ml, p < 0.01), plasma IL-6, and CCL3 between responders and nonresponders (0.136 versus 3.84 pg/ml, p < 0.005; 30.5 versus 32.4, p < 0.05) and released IL-6 from dexamethasone stimulated PBMC in AIED patients compared with controls (0.54 versus 1.12 pg/ml, p < 0.001). There was a correlation between plasma IL-6 levels of AIED patients to both serum CRP and cardiac CRP (R2 = 0.83, R2 = 0.88). CONCLUSIONS We observed AIED patients, specifically nonresponders expressed greater levels of IL-6. Elevated IL-6 levels in AIED patients correlated with CRP levels, providing a commonly available laboratory test that may aid in rapid clinical decision-making in these patients.

FISH & SHELLFISH IMMUNOLOGY 2021; 116:12-18. [PMID: 33965526 DOI: 10.1016/j.fsi.2021.05.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Revised: 04/26/2021] [Accepted: 05/03/2021] [Indexed: 06/12/2023]
Abstract
Triploid induction is a promising biotechnique that could be used to enhance aquaculture yields in the near future. However, studies conducted with several fish species have demonstrated that the presence of an extra set of chromosomes may result in deleterious health effects. Furthermore, studies of fish immune responses still need to be conducted before these specimens can be readily commercialized. In the study presented herein, we evaluated the effects of triploid induction on hematology, erythrocyte morphometry and morphology, phagocytosis, and the expression levels of IL-1β and TGF-β using specimens of the Neotropical species, Astyanax altiparanae. In general, the cell counts of erythrocytes, leukocytes, and neutrophils in triploid fish were lower than those in diploid fish. The erythrocytes of triploid fish were larger than those found in diploid fish, but also demonstrated considerably higher frequencies of cellular and nuclear abnormalities. Although not statistically significant, triploid induction resulted in a phagocytic capacity (PC) 20% lower than that found with diploid fish. No notable differences were observed in phagocytic index (PI). Gene expression levels for the cytokine IL-1 were lower in tissues from the head kidney, liver, and spleen of triploid fish with respect to diploid fish. Gene expression levels of TGF-β were lower only in the spleen of triploids compared to diploids. In conclusion, triploid induction resulted in A. altiparanae specimens with immune impairments and potentially lower resistances to disease and low-quality environments.

Abstract
The development of replacement heifers is crucial for breeding success and herd efficiency. Nutritional management can affect not only reproductive development but also the inflammatory status of the uterine environment, which may impact reproductive functions such as pregnancy establishment and development. The study herein evaluated the concentration of cytokines and chemokines in the uterus of heifers supplemented with different levels of protein. Angus heifers (n = 60) were blocked by body weight (BW) and randomly assigned to 1 of 3 treatments based on protein supplementation level: control of 10% crude protein (CON), 20% crude protein (P20), or 40% crude protein (P40). BW, body condition score, and blood samples were taken every 2 wk for 140 d to monitor development. Uterine flushes were performed monthly and concentrations of cytokines (IL-1α, IL-1β, TNF-α, IFN-γ, IL-10, VEGF-α, IL-17A, and IL-36RA) and chemokines (IL-8, MCP-1, MIP-1α, and MIP-1β) were quantified via ELISA multiplex. To test if there were mean differences in cytokines between the treatment groups or over time, PROC GLIMMIX (SAS v 9.4) was utilized. Concentrations of all cytokines and chemokines, except IL-1α, changed throughout heifer development (P < 0.05). Heifers in the P40 treatment group displayed reduced concentrations of MCP-1 (P = 0.007) and tended to have decreased concentrations of IFN-γ (P = 0.06). Cytokine IL-36RA tended (P = 0.06) to be affected by protein level, with the lowest concentrations observed in CON heifers. Most cytokines and chemokines increased following the initial month of supplementation (P < 0.05). The increase in concentrations after 1 mo may indicate an adaptive response in the uterus to diet change. Cytokines and chemokines fluctuated due to physiological changes occurring during development. Further research is needed to determine the influence of nutrition on uterine inflammation and long-term impacts on reproductive function.

Patrushev AV, Samtsov AV, Soukharev AV. Features of the cytokine profile and the effectiveness of radical treatment of focal infection in patients with psoriasis. VESTNIK DERMATOLOGII I VENEROLOGII 2021.

Abstract
Background. Focal infection (FI) are important trigger factors for the development of psoriasis, which means they can aggravate the course of dermatosis, including due to an increase in certain pro-inflammatory cytokines in the blood.
Aim. To study the cytokine profile of patients with psoriasis in the progressive period of the disease, as well as to assess the effect radical treatment of focal infection on the course of dermatosis.
Material and methods. Prospective comparative non-randomized study included 52 patients with psoriasis vulgaris, aged 18 to 65 years, who signed a informed consent. The first group consisted of patients who underwent radical treatment FI (16 people), the second those who did not treat FI (16 people), and the third group consisted of patients in whom FI was not detected (20 people).
Cytokine concentrations were measured in the progressive stage of the disease in 52 patients with psoriasis and 20 individuals in the control group (healthy individuals).The spectrum of detected cytokines included: IL-1, IL-2, IL-4, IL-6, IL-8, IL-10, IL-17A, as well as INF- and INF-. For the detection of all cytokines, except for IL-17A, reagents from Vector-Best, Russia were used. The Human ELISA MAX Deluxe Set (BioLegend, USA) was used to determine the concentration of IL-17A.
During the main course of treatment (0, 2 and 4 weeks), as well as the follow-up of patients (12, 24 and 52 weeks), the severity of psoriasis was assessed with the calculation of the PASI index. At the end of the study (week 52), the number of relapses and the total duration of remission were recorded.
Results. The level of IL-8 was increased in 90,6% of psoriasis patients with FI. In this case, significant differences were obtained in comparison with the group of patients with psoriasis without diagnosed FI and with the control group, in which an increase in the concentration of IL-8 was noted, respectively, in 65% and 30% of cases. A moderate positive correlation was found between the IL-8 level and the PASI index (rs = 0,48; p = 3,6 104). The levels of INF- and IL-6 in psoriasis patients with FI were increased, respectively, in 15,6% and 21,9% of cases and significantly differed from the group of practically healthy individuals (p 0,05), differences from the group of patients with psoriasis without FI was not identified. The concentration of TNF- did not differ in all three groups. The level of IL-17A was significantly increased in comparison with practically healthy individuals both in the group of psoriasis patients with FI and in the group of patients without FI (Me = 3,3 and 4,3 pg/ml versus 0,2 pg/ml). The concentrations of five interleukin cytokines, namely IL-1, IL-2, IL-4, IL-10 and INF-, did not exceed the upper limit of the reference range in all patients of the experimental (patients with psoriasis) and control groups.
Evaluation of the PASI index during the observation of patients in the first and second groups showed significantly lower values of this indicator for weeks 24 and 52 in the first group (0,2 vs. 7,0; p = 0,02 and 0,1 vs. 7,2; p = 0,002). The relative risk of disease recurrence in the absence of radical treatment for FI was 2,6 (CI 1,1 to 5,2).
Conclusion. Data were obtained showing the role of IL-8 and focal infection, with the presence of which its increased production is associated, in the worsening of the course of psoriasis with the frequent development of relapses. Important preventive measures leading to a decrease in the number of relapses of psoriasis are timely diagnosis and radical treatment of focal infection.

Yamaguchi M, Fukasawa S. Is Inflammation a Friend or Foe for Orthodontic Treatment?: Inflammation in Orthodontically Induced Inflammatory Root Resorption and Accelerating Tooth Movement. Int J Mol Sci 2021; 22:2388. [PMID: 33673606 PMCID: PMC7957544 DOI: 10.3390/ijms22052388] [Citation(s) in RCA: 51] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Revised: 02/20/2021] [Accepted: 02/22/2021] [Indexed: 02/07/2023] Open
Abstract
The aim of this paper is to provide a review on the role of inflammation in orthodontically induced inflammatory root resorption (OIIRR) and accelerating orthodontic tooth movement (AOTM) in orthodontic treatment. Orthodontic tooth movement (OTM) is stimulated by remodeling of the periodontal ligament (PDL) and alveolar bone. These remodeling activities and tooth displacement are involved in the occurrence of an inflammatory process in the periodontium, in response to orthodontic forces. Inflammatory mediators such as prostaglandins (PGs), interleukins (Ils; IL-1, -6, -17), the tumor necrosis factor (TNF)-α superfamily, and receptor activator of nuclear factor (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) are increased in the PDL during OTM. OIIRR is one of the accidental symptoms, and inflammatory mediators have been detected in resorbed roots, PDL, and alveolar bone exposed to heavy orthodontic force. Therefore, these inflammatory mediators are involved with the occurrence of OIIRR during orthodontic tooth movement. On the contrary, regional accelerating phenomenon (RAP) occurs after fractures and surgery such as osteotomies or bone grafting, and bone healing is accelerated by increasing osteoclasts and osteoblasts. Recently, tooth movement after surgical procedures such as corticotomy, corticision, piezocision, and micro-osteoperforation might be accelerated by RAP, which increases the bone metabolism. Therefore, inflammation may be involved in accelerated OTM (AOTM). The knowledge of inflammation during orthodontic treatment could be used in preventing OIIRR and AOTM.

Abstract
Bordetella pertussis is a highly contagious pathogen which causes whooping cough in humans. A major pathophysiology of infection is the extrusion of ciliated cells and subsequent disruption of the respiratory mucosa. Tracheal cytotoxin (TCT) is the only virulence factor produced by B. pertussis that has been able to recapitulate this pathology in animal models. This pathophysiology is well characterized in a hamster tracheal model, but human data are lacking due to scarcity of donor material. We assessed the impact of TCT and lipopolysaccharide (LPS) on the functional integrity of the human airway mucosa by using in vitro airway mucosa models developed by co-culturing human tracheobronchial epithelial cells and human tracheobronchial fibroblasts on porcine small intestinal submucosa scaffold under airlift conditions. TCT and LPS either alone and in combination induced blebbing and necrosis of the ciliated epithelia. TCT and LPS induced loss of ciliated epithelial cells and hyper-mucus production which interfered with mucociliary clearance. In addition, the toxins had a disruptive effect on the tight junction organization, significantly reduced transepithelial electrical resistance and increased FITC-Dextran permeability after toxin incubation. In summary, the results indicate that TCT collaborates with LPS to induce the disruption of the human airway mucosa as reported for the hamster tracheal model.

Abstract
Spinal cord injury (SCI) is one of the most destructive traumatic diseases in human beings. The balance of inflammation in the microenvironment is crucial to the repair process of spinal cord injury. Inflammatory cytokines are direct mediators of local lesion inflammation and affect the prognosis of spinal cord injury to varying degrees. In spinal cord injury models, some inflammatory cytokines are beneficial for spinal cord repair, while others are harmful. A large number of animal studies have shown that local targeted administration can effectively regulate the secretion and delivery of inflammatory cytokines and promote the repair of spinal cord injury. In addition, many clinical studies have shown that drugs can promote the repair of spinal cord injury by regulating the content of inflammatory cytokines. However, topical administration affects only a small portion of inflammatory cytokines. In addition, different individuals have different inflammatory cytokine profiles during spinal cord injury. Therefore, future research should aim to develop a personalized local delivery therapeutic cocktail strategy to effectively and accurately regulate inflammation and obtain substantial functional recovery from spinal cord injury.

Kim SB, Cho J, Jue SS, Park JH, Kim JY. Effect of Hyaluronic Acid Filler Injection on the Interdental Papilla in a Mouse Model of Open Gingival Embrasure. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E4956. [PMID: 32660062 PMCID: PMC7400429 DOI: 10.3390/ijerph17144956] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 07/04/2020] [Accepted: 07/05/2020] [Indexed: 02/07/2023]
Abstract
The black triangle resulting from interdental papilla (IDP) loss is associated with poor aesthetics and difficulty in pronunciation and food impaction. There is limited knowledge of gingival tissue inflammatory response to hyaluronic acid (HA) filler injection, a minimally invasive IDP reconstruction method. This study aimed to examine the morphological and histological changes in IDP and the inflammatory cytokine localization to the IDP post-HA filler injection using an open gingival embrasure (OGE) mouse model. Mice from the control, sham, and OGE groups were attached with reference, inactive, and activated wires for 5 days, respectively. The degree of IDP loss was determined based on the spring-papilla distance (SPD). Morphological and histological changes in the OGE group injected with phosphate-buffered saline (PBS) or HA fillers were examined on days 2 and 7 post-injection. Immunohistochemical analysis was performed to determine the localization patterns of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, myeloperoxidase (MPO), and Ki67. Five days post-wire attachment, the control and OGE groups exhibited a significantly higher SPD than the sham group (p < 0.0167). The SPD of the HA filler injection group was significantly lower than that of the PBS injection group on days 2, 4, and 7 post-injection (p < 0.05). The IDP of the OGE group was wide and flat. HA filler was stable in the connective tissue underlying the epithelial tissue even on day 7 post-injection. TNF-α, IL-1β, IL-6, MPO, and Ki67 were highly localized to the connective tissue surrounding the filler on day 2, which decreased on day 7 post-injection. Thus, HA filler can safely and successfully reconstruct the IDP in cases of OGE.

Abstract
OBJECTIVE The aim of this study was to evaluate the levels of Interleukin-1α (IL-1α), Interleukin-1β (IL-1β), Interleukin-1 receptor antagonist (IL-1Ra), Interleukin-10 (IL-10), Interleukin-13 (IL-13), Vascular endothelial growth factor (VEGF), Granulocyte-colony stimulating factor (G-CSF), and Growth related oncogene (GRO) in the peri-miniscrew implant crevicular fluid (MICF) under orthodontic loading. DESIGN The study sample comprised 14 miniscrews immediately loaded and 17 unloaded ones. A load of 200gF was immediately applied to the miniscrews in the loaded group after the placement surgery. Peri-miniscrew implant crevicular fluid was collected at baseline, at day 7, and at day 21. The levels of the biomarkers were measured using a multiplexed bead immunoassay. Intergroup comparisons were made using Mann-Whitney test. Friedman and Dunn's multiple comparison tests were used to evaluate intragroup differences over time. RESULTS Although no statistical differences were observed between the groups at any time point for any of the 8 biomarkers evaluated, there was a statistically significant increase (p < 0.02) in the levels of all the biomarkers over time on both groups. CONCLUSIONS An immediate loading of 200gF does not alter the balance in the inflammatory response in peri-miniscrew tissues.

Abstract
Adult multipotent stem/progenitor cells, with remarkable regenerative potential, have been isolated from various components of the human periodontium. These multipotent stem/progenitor cells include the periodontal ligament stem/progenitor cells (PDLSCs), stem cells from the apical papilla (SCAP), the gingival mesenchymal stem/progenitor cells (G-MSCs), and the alveolar bone proper stem/progenitor cells (AB-MSCs). Whereas inflammation is regarded as the reason for tissue damage, it also remains a fundamental step of any early healing process. In performing their periodontal tissue regenerative/reparative activity, periodontal stem/progenitor cells interact with their surrounding inflammatory micro-environmental, through their expressed receptors, which could influence their fate and the outcome of any periodontal stem/progenitor cell-mediated reparative/regenerative activity. The present review discusses the current understanding about the interaction of periodontal stem/progenitor cells with their surrounding inflammatory micro-environment, elaborates on the inflammatory factors influencing their stemness, proliferation, migration/homing, differentiation, and immunomodulatory attributes, the possible underlying intracellular mechanisms, as well as their proposed relationship to the canonical and noncanonical Wnt pathways.

Abstract
The balance of inflammation is critical to the repair of spinal cord injury (SCI), which is one of the most devastating traumas in human beings. Inflammatory cytokines, the direct mediators of local inflammation, have differential influences on the repair of the injured spinal cord. Some inflammatory cytokines are demonstrated beneficial to spinal cord repair in SCI models, while some detrimental. Various animal researches have revealed that local delivery of therapeutic agents efficiently regulates inflammatory cytokines and promotes repair from SCI. Quite a few clinical studies have also shown the promotion of repair from SCI through regulation of inflammatory cytokines. However, local delivery of a single agent affects only a part of the inflammatory cytokines that need to be regulated. Meanwhile, different individuals have differential profiles of inflammatory cytokines. Therefore, future studies may aim to develop personalized strategies of locally delivered therapeutic agent cocktails for effective and precise regulation of inflammation, and substantial functional recovery from SCI.

Abstract
The acute phase response is generated by an overwhelming immune-inflammatory process against infection or tissue damage, and represents the initial response of the organism in an attempt to return to homeostasis. It is mediated by acute phase proteins (APPs), an assortment of highly conserved plasma reactants of seemingly different functions that, however, share a common protective role from injury. Recent studies have suggested a crosstalk between several APPs and the mononuclear phagocyte system (MPS) in the resolution of inflammation, to restore tissue integrity and function. In fact, monocyte-derived dendritic cells (Mo-DCs), an integral component of the MPS, play a fundamental role both in the regulation of antigen-specific adaptive responses and in the development of immunologic memory and tolerance, particularly in inflammatory settings. Due to their high plasticity, Mo-DCs can be modeled in vitro toward a tolerogenic phenotype for the treatment of aberrant immune-inflammatory conditions such as autoimmune diseases and allotransplantation, with the phenotypic outcome of these cells depending on the immunomodulatory agent employed. Yet, recent immunotherapy trials have emphasized the drawbacks and challenges facing tolerogenic Mo-DC generation for clinical use, such as reduced therapeutic efficacy and limited in vivo stability of the tolerogenic activity. In this review, we will underline the potential relevance and advantages of APPs for tolerogenic DC production with respect to currently employed immunomodulatory/immunosuppressant compounds. A further understanding of the mechanisms of action underlying the moonlighting immunomodulatory activities exhibited by several APPs over DCs could lead to more efficacious, safe, and stable protocols for precision tolerogenic immunotherapy.

Abstract
Interferon-alpha might increase triglyceride serum levels through the enhancement of hepatic lipogenesis and/or inhibition of the peripheral lipoprotein lipase. Hypertriglyceridemia during interferon-alpha therapy has been only recently described, mostly in patients with previous abnormalities of lipid metabolism. The authors report here a case of a 65-year-old male bearing advanced colon carcinoma who developed hypertriglyceridemia during long-term interferon-alpha treatment in association with 5 fluorouracil administration. Hypertriglyceridemia was maintained within acceptable levels, without adjusting the treatment plan, by an appropriate diet and gemfibrosil administration.

Abstract
An in vivo cross-over study has investigated plasma and cellular levels of IL-1 (IL-1α IL-1β and IL-1Ra) when using Cuprophan (C) and cellulose triacetate (CTA) membranes to assess the roles of complement activation and dialysate endotoxin content in the induction of cytokines during the dialysis procedure. The mean C5a level during Cuprophan dialysis was 29.9 ± 0.63 ng/ml (Mean ± SEM), while for the cellulose triacetate dialysis was 3.09 ± 0.7 ng/ml. The endotoxin content of the dialysate was 0.31 ± 0.34 EU/ml and 0.68 ± 1.39 EU/ml. These two factors failed to produce measurable changes in plasma or cellular IL-1α and IL-1β levels during treatment. The plasma IL-1Ra levels pre-dialysis were similar to those for normal controls (CTA 769 ± 156 ng/ml, C739 ± 93, normal controls 635 ± 33) with a considerable day to day variation. A membrane independent fall in plasma IL-1Ra at 15 minutes was noted (CTA 420 ± 92 ng/ml, C 503 ± 139) with a return to pre-dialysis levels by the end of treament. Cellular IL-1Ra levels pre-dialysis were similar to the normal group - (CTA 1904 ± 291 ng/ml, C 1564 ± 292 and normal control 1971 ± 368). However, on average, the values when using cellulose triacetate were 655 ± 623 pg/ml higher than for Cuprophan (p=0.03). These findings indicate that the measurement of plasma cytokine levels is of limited use in the study of cytokine induction by the haemodialysis procedure and that IL-1Ra may be a better indicator of the host response to cytokine stimuli during treatment. However, a considerable inter-patient and intra-treatment variation is present and further studies are required to elucidate the factors involved.

Abstract
OBJECTIVE To study the anti-inflammatory properties of OJ. CONTEXT Ojayeonjonghwan (OJ) is a traditional Korean prescription, which has been widely used for the treatment of prostatitis. However, no scientific study has been performed of the anti-inflammatory effects of OJ. MATERIALS AND METHODS Peritoneal macrophages were isolated 3-4 days after injecting a C57BL/6J mouse with thioglycollate. They were then treated with OJ water extract (0.01, 0.1, and 1 mg/mL) for 1 h and stimulated with lipopolysaccharide (LPS) for different times. Nitric oxide (NO), inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2, and proinflammatory cytokine levels were determined by NO assay, Western blotting, RT-PCR and ELISA. RESULTS NO generation and iNOS induction were increased in the LPS-activated mouse peritoneal macrophages. However, NO generation and iNOS induction by LPS were suppressed by treatment with OJ for the first time. The IC50 value of OJ with respect to NO production was 0.09 mg/mL. OJ did not influence LPS-stimulated COX-2 induction, but did significantly decrease LPS-stimulated secretions and mRNA expressions of tumour necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β. Inhibition rates of TNF-α, IL-6, and IL-1β at an OJ concentration of 1 mg/mL were 77%, 88%, and 50%, respectively. OJ also suppressed the LPS-induced nuclear translocation of NF-κB. High-performance liquid chromatography showed schizandrin and gomisin A are major components of OJ. CONCLUSIONS OJ reduces inflammatory response, and this probably explains its positive impact on the prostatitis associated inflammation.

Abstract
The present study describes the purification and partial characterization of a basic anticoagulant PLA2 enzyme named as Rv(i) PLA2 from the venom of Indian Daboia russelii. The molecular mass of the protein was found to be 13,659.65 Da, and peptide mass fingerprinting revealed that it belongs to group II PLA2 family. The peptide sequence showed similarity to uncharacterized basic PLA2 enzyme having an accession no. of P86368 reported from Sri Lankan D. russelii. Rv(i) PLA2 exhibited strong phospholipase A2 and anticoagulant activity. It also induced expression of COX-2 and TNF-α mRNA in a dose-dependent manner in phorbol 12-myristate 13-acetate differentiated THP-1 cells, which play a crucial role during inflammation. Chemical modification of His residue in Rv(i) PLA2 with p-bromophenacyl bromide abolished the enzymatic, anticoagulant, and inflammatory activities. The result indicates that the catalytic site of Rv(i) PLA2 might play a vital role in inducing inflammation at the bite site during D. russelii envenomation.

Abstract
Through continuous cardiac output monitoring, we investigated the temporal relationship between hemodynamic changes and plasma cytokines in a cancer patient who developed collateral sepsis to immunotherapy. A 52-year-old male with metastatic renal cell carcinoma received interleukin-2 (IL-2) infusion completing 72 h of administration. The patient developed 3 sepsis-like states including systemic inflammatory response syndrome (SIRS), shock, and multiple organ dysfunction syndrome (MODS). Hemodynamic parameters including systemic vascular resistance index (SVRI), left ventricular stroke work index (LVSWI) and cardiac index (CI) were measured over 60 h. Peripheral blood was drawn when SVRI dropped 20% in the patient and plasma cytokines including TNF-α , IL-6 and IL-1β were measured using ELISA. After 60 h of immunotherapy, the patient showed a 63.4% decrease in SVRI, 54.5% decrease in LVSWI and 65.4% increase in CI. The evaluation of systemic cytokines revealed different kinetic patterns: (i) a sustained increase in TNFα levels through all 3 sepsis-like states; (ii) IL-6 increased preferentially during SIRS and shock, while up/down-responses were found during MODS; (iii) IL-1β was undetectable during the entire study period. A high temporal relationship between hemodynamic changes and plasma TNF-α, but not IL-6, was found. Although there are factors other than cytokines that can alter vascular resistance, this finding could represent an approach to evaluate the course of hemodynamia and probably the systemic cytokine expression after IL-2 administration in renal cancer.

Abstract
The expression of adhesion molecules on human vascular endothelial cells (EC) during infection or inflammation is necessary to initiate migration of leukocytes to the disease focus. Various bacteria or endotoxins (lipopolysaccharide, LPS) might exert differential capacity to induce adhesion molecules in endothelial cells. Therefore, we first investigated induction of adhesion by bacteria. Heat-killed Gram-negative bacteria (Escherichia coli) induced adhesion, whereas the Gram-positive Bacillus subtilis and Staphylococcus epidermidis or Mycobacterium tuberculosis did not, indicating the significance of LPS for this activation. Purified S-form LPS stimulated endothelial cells to express adhesion molecules for polymorphonuclear cells (PMN) or lymphocytes in a dose-dependent fashion. S-form LPS, containing an 0-specific chain, induced a maximal level of adhesion, comparable to adhesion induced by interleukin-1 (IL-1). We obtained the same results in cell ELISA with anti-ICAM-1 antibody (84H10). R-form LPS and free lipid A, lacking an O-specific chain also stimulated adhesion, however, to a lower degree (39-60%). Synthetic lipid A precursor Ia (compound 406) or another LPS-antagonist (non-toxic Rhodobacter capsulatus LPS) did not trigger endothelial cells to express adhesion molecules. These antagonists specifically inhibited LPS- or free lipid A-, but not IL-1-induced adhesion. These results suggest that lipid A is the active structure of LPS necessary for induction of adhesion, that the oligosaccharide portion is important for the capacity of LPS to stimulate adhesion, and that activation of adhesion to endothelial cells by LPS requires specific LPS binding sites.

RNA Interference Mediated Interleukin-1β Silencing in Inflamed Chondrocytes Decreases Target and Downstream Catabolic Responses. ARTHRITIS 2016; 2016:3484961.

Abstract
Posttraumatic activation of the catabolic cascade plays a major role in degradation of cartilage. Interleukin-1β (IL-1β), a primary instigator in the catabolic axis, is upregulated in chondrocytes following injury. IL-1β activates key degradative enzymes, including MMPs and aggrecanases, and other proinflammatory mediators such as PGE2 which contribute to ECM breakdown. Posttranscriptional silencing of IL-1β by RNA interference (RNAi) may drive a reduction in IL-1β. We hypothesized that transduction of chondrocytes using rAAV2 expressing a short hairpin RNAi motif targeting IL-1β (shIL-1β) would significantly decrease IL-1β expression and, in turn, decrease expression of other catabolic enzymes. Chondrocyte cultures were transduced with rAAV2-tdT-shIL-1β in serum-free media. The fluorescent protein, tdTomato, was used to determine transduction efficiency via flow cytometry and fluorescent microscopy. Cells were stimulated with lipopolysaccharide (LPS) 48 hours following transduction. After 24-hour stimulation, supernatants were collected for cytokine analysis, and cells lysed for gene expression analysis. IL-1β knockdown led to significantly decreased expression of IL-1β, TNF-α, and ADAMTS5. PGE2 synthesis was also significantly downregulated. Overall, effective silencing of IL-1β using rAAV2 vector expressing a short hairpin IL-1β knockdown sequence was shown. Additionally, significant downstream effects were evident, including decreased expression of TNF-α and ADAMTS5. Targeted silencing of catabolic cytokines may provide a promising treatment avenue for osteoarthritic (OA) joints.

Abstract
Recent advancement in fermentation technologies resulted in the increased yields of recombinant proteins of biopharmaceutical and medicinal importance. Consequently, there is an important task to develop simple and easily scalable methods that can facilitate the production of high-quality recombinant protein. Most of the recent reports described the expression of recombinant human IL-1 receptor antagonist (rhIL-1Ra) in Escherichia coli using isopropyl-β-d-thiogalacto pyranoside (IPTG), a nonmetabolizable and expensive compound, as an expression inducer. In this study, we describe the expression and one-step purification of gallbladder-derived rhIL-1Ra by autoinduction in E. coli. This method includes special media that automatically induce the target protein expression from T7 promoter and allow the production of the target protein in high yield than the conventional IPTG induction method. In addition to fermentation process improvements, one-step purification strategy is essential to make the process economical. We developed a single-step cation exchange chromatography and obtained 300 mg/L of rhIL-1Ra with 98% purity. Purified protein was characterized by SDS-PAGE and Ion exchange HPLC (IEX-HPLC). The described method can be used to scale up the production of rhIL-1Ra and other recombinant proteins.

Abstract
Physical exercise reportedly stimulates IL-1 production within working skeletal muscles, but its physiological significance remains unknown due to the existence of two distinct IL-1 isoforms, IL-1α and IL-1β. The regulatory complexities of these two isoforms, in terms of which cells in muscles produce them and their distinct/redundant biological actions, have yet to be elucidated. Taking advantage of our masticatory behavior (Restrained/Gnawing) model, we herein show that IL-1α/1β-double-knockout (IL-1-KO) mice exhibit compromised masseter muscle (MM) activity which is at least partially attributable to abnormalities of glucose handling (rapid glycogen depletion along with impaired glucose uptake) and dysfunction of IL-6 upregulation in working MMs. In wild-type mice, masticatory behavior clearly increased IL-1β mRNA expression but no incremental protein abundance was detectable in whole MM homogenates, whereas immunohistochemical staining analysis revealed that both IL-1α- and IL-1β-immunopositive cells were recruited around blood vessels in the perimysium of MMs after masticatory behavior. In addition to the aforementioned phenotype of IL-1-KO mice, we found the IL-6 mRNA and protein levels in MMs after masticatory behavior to be significantly lower in IL-1-KO than in WT. Thus, our findings confirm that the locally-increased IL-1 elicited by masticatory behavior, although present small in amounts, contributes to supporting MM activity by maintaining normal glucose homeostasis in these muscles. Our data also underscore the importance of IL-1-mediated local interplay between autocrine myokines including IL-6 and paracrine cytokines in active skeletal muscles. This interplay is directly involved in MM performance and fatigability, perhaps mediated through maintaining muscular glucose homeostasis.

Abstract
Signaling through the IL-1-receptor type 1 (IL-1R1), IL-1 is required for initiation and maintenance of diverse activities of the immune system. A second receptor, IL-1R2, blocks IL-1 signal transduction. We studied expression of IL-1beta, IL-1R1, and IL-1R2 in 17 Hodgkin lymphomas (HL) by in situ hybridization (ISH). IL-1beta expressing cells, morphologically consistent with endothelial cells and fibroblasts, occurred in all HL tissues with elevated transcript levels in areas of active fibrosis. Hodgkin and Reed-Sternberg (HRS) cells of all cases expressed low IL-1R1 transcript levels in some tumor cells, and high levels of IL-1R2 in large proportions of HRS cells. Only few bystander cells showed low levels of IL-1R1 and IL-1R2 RNA. Supernatants of 4 out of 7 HL-derived cell lines contained soluble IL-1R2 protein at high levels. HL patient sera carried variably amounts of IL-1R2 protein with significantly increased titers in patients with active disease compared to patients in complete remission and control individuals without HL. Western blots and co-immunoprecipitations showed binding of the IL-1R2 to the intracellular IL-1R-accessory protein (IL-1IRAcP). These data suggest functions of the IL-1R2 as a „decoy-receptor” sequestrating paracrine IL-1 extracellularly and intracellularly by engaging IL-1IRAcP, thus depriving IL1-R1 molecules of their extracellular and intracellular ligands. Expression of IL1-R2 by HRS cells seems to contribute to local and systemic modulation of immune function in HL.

Abstract
BACKGROUND Trait anger consists of affective, behavioral, and cognitive (ABC) dimensions and may increase vulnerability for interpersonal conflict, diminished social support, and greater psychological distress. The concurrent influence of anger and psychosocial dysfunction on Human Immunodeficiency Virus (HIV) disease severity is unknown. PURPOSE The purpose of this study was to examine plausible psychosocial avenues (e.g., coping, social support, psychological distress), whereby trait anger may indirectly influence HIV disease status. METHODS Three hundred seventy-seven HIV seropositive adults, aged 18-55 years (58% AIDS-defined), completed a battery of psychosocial surveys and provided a fasting blood sample for HIV-1 viral load and T lymphocyte count assay. RESULTS A second-order factor model confirmed higher levels of the multidimensional anger trait, which was directly associated with elevated psychological distress and avoidant coping (p<.001) and indirectly associated with greater HIV disease severity (p<.01) (comparative fit index (CFI)=0.90, root-mean-square error of approximation (RMSEA)=0.06, standardized root-mean-square residual (SRMR)=0.06). CONCLUSION The model supports a role for the ABC components of anger, which may negatively influence immune function through various psychosocial mechanisms; however, longitudinal study is needed to elucidate these effects.

Abstract
Inflammatory abnormalities have been implicated in the pathogenesis of various human diseases, including cancer. Interleukin-1 receptor antagonist (IL1RN) is a potent anti-inflammatory molecule that modulates the biological activity of the proinflammatory cytokine, interleukin-1. The aim of this study was to examine the expression of IL1RN in oral squamous cell carcinomas (OSCCs), and to determine its clinical significance. Expression levels of IL1RN in matched normal and tumor specimens from 39 OSCCs were evaluated using real-time quantitative polymerase chain reaction methods, and immunohistochemical analysis. Protein expression of IL1RN was also examined in 18 oral premalignant lesions (OPLs). Expression of IL1RN mRNA was significantly downregulated in OSCCs compared with normal tissues. Decreased expression of IL1RN protein was also observed in OPLs and OSCCs. The IL1RN expression level was lower in the OPL cases with severe dysplasia compared to those with mild/moderate dysplasia. Significantly downregulated IL1RN expression was observed in all OSCC lesion sites examined when compared with the matched normal tissues. However, the decreased level of IL1RN expression did not correspond with tumor progression. Noteworthy, IL1RN expression was higher in the advanced OSCC cases (T3/T4) compared to early cases (T1/T2). Among OSCC samples, relatively higher IL1RN expression was associated with active tumor development in the OSCCs occurring in the buccal mucosa, oral floor, fauces and gingiva, but not the tongue. These data suggest that IL1RN may exhibit opposing characteristics in oral malignancies depending on the stage of cancer development, suppressing early carcinogenic events, yet promoting tumor development in some lesion sites. Thus, IL1RN could represent a reliable biomarker for the early diagnosis of OSCCs. Furthermore, IL1RN may possess unknown and complex functions in the developed OSCC.

Abstract
Purification of human IL-1β is used in this unit as an example of the preparation of a soluble protein from E. coli. Bacteria containing IL-1β are lysed, and IL-1 β in the resulting supernatant is purified by anion-exchange chromatography, salt precipitation, and cation-exchange chromatography, and then concentrated. Finally, the IL-1 β protein is applied to a gel-filtration column to separate it from remaining higher- and lower-molecular-weight contaminants, the purified protein is stored frozen or is lyophilized. The purification protocol described is typical for a protein that is expressed in fairly high abundance (i.e., >5% total protein) and accumulates in a soluble state. In addition, the purification procedure serves as an example of how to use classical protein purifications methods, which may also be used in conjunction with the affinity-based methods now more commonly used.

Abstract
Macrophages play an important role in attempt to eliminate mycobacteria, via production of cytokines, including interleukin-1, and interleukin-12. Bacillus Calmitte Guerin (BCG) vaccination, known to induce interleukin-1β in tuberculosis, was originally aimed at tuberculosis control, but it showed efficacy against leprosy. Our aim was to estimate serum levels of interleukin-1β and interleukin-12, in leprosy, and to assess the impact of previous BCG vaccination on their levels. Serum interleukin-1β and interleukin-12 p70 were estimated in 43 leprotic patients and 43 controls by enzyme-linked immunosorbent assay. Patients were grouped according to presence or absence of reactions, as well as bacillary load. Serum interleukin-1β was significantly higher in patients as compared to controls (p = 0.047), and was significantly different in patients' groups (p = 0.036); with significantly higher level in multibacillary patients, both non reactional and with erythema nodosum leprosum, compared with paucibacillary/non reactional patients (p = 0.012 and 0.049 respectively). A statistically significant higher interleukin-1β was found in BCG vaccinated paucibacillary patients as compared to unvaccinated patients (p = 0.031). Significantly elevated interleukin-12 was present in patients as compared to controls (p < 0.001), with no statistically significant difference comparing patients' groups. BCG vaccination showed stimulatory effect on monocytes only in the immunocompetent paucibacillary leprosy patients, as evidenced by higher Interleukin-1β in this group. Interleukin-1β was shown to have a pro-inflammatory role in multibacillary patients with or without erythema nodosum leprosum. Targeting interleukin-1β may be promising to control episodic refractory erythema nodosum leprosum. Interleukin-12 may be a general marker of active Mycobacterium leprae infection.

Abstract
The present study was undertaken to investigate correlation between some hematological parameters, acute phase proteins and immunoglobulins in the experimentally infected goats with Besnoitia caprae from the time of infection till 360 days post infection (DPI). Six male goats, approximately 12-16 months old, were inoculated subcutaneously with approximately 1.3 × 10(8) bradyzoites of B. caprae and blood samples were collected at weekly intervals from the jugular vein of the goats. Total leukocyte count and differential leukocyte counts were determined. Acute phase proteins (APPs) including serum amyloid A (SAA), haptoglobin (Hp), fibrinogen and ceruloplasmin were undertaken at weekly intervals. We evaluated an enzyme-linked immunosorbent assay (ELISA) (using a somatic antigen of bradyzoite) to detect anti-B. caprae antibodies in caprine sera. Cysts were present in the skin biopsies of the distal parts of the leg of the infected goats from 28 DPI. From 30 to 360 DPI, results showed that the APPs concentrations including SAA, Hp, fibrinogen and ceruloplasmin were enhanced in the serum of infected goats. However, there were some variation in hematological parameters; the differences were not significant with those of the normal values. Some variations were seen in the levels of specific antibodies against this parasite and they had correlation with some hematological parameters and acute-phase proteins.

Deep functional changes occurring within the endometrium during implantation are orchestrated by embryonic and maternal signals. Human chorionic gonadotropin (hCG), a major embryonic signal, plays a critical role in the initiation and maintenance of pregnancy. Interleukin (IL) 1, one of the earliest embryonic signals, appears to exert a direct impact on the receptive endometrium and to induce major molecular changes that are essential for embryo implantation. Herein we investigate whether hCG can modulate endometrial stromal cell (ESC) receptivity to IL1 during the implantation window and assess the impact on angiogenesis in vitro. Primary cultures of ESCs from normal fertile women during the implantation window were treated for 24 h with different concentrations of hCG (0-100 ng/ml) and stimulated for 24 h with IL1B (0-0.1 ng/ml). IL1 receptors (IL1Rs), IL1R antagonist (IL1RA), and monocyte chemotactic protein (MCP) 1 were analyzed by real-time PCR, ELISA, and Western blotting. The angiogenic activity in vitro was studied using human microvascular endothelial cell line, scratch wound assay, and cell proliferation via BrdU incorporation into DNA. Human CG induced a dose-dependent imbalance in ESC receptivity to IL1 by significantly upregulating the functional signaling IL1R1 and concomitantly downregulating the decoy inhibitory IL1R2 and IL1RA upon subsequent exposure to IL1B. Prior exposure to hCG amplified MCP1 secretion by ESCs in response to IL1B and triggered the release of angiogenic activity in vitro in which MCP1 appeared to play a significant role. Overexpression of IL1R2 using cell transfection inhibited IL1 and hCG/IL1B-mediated MCP1 secretion. These findings suggest that hCG coordinates embryonic signal interaction with the maternal endometrium, and point to a new possible pathway by which it may promote embryonic growth.

Abstract
In this work we have focused on the ability of interleukin-1 to induce an acute phase protein response and a degranulation of polymorphonuclear leukocytes in vivo. The capacity of the interleukin-1 receptor antagonist to influence these events was also investigated. It was shown that interleukin-1 induced an acute phase protein response in rats and mice. In rats alpha(2)-macroglubolin levels were increased in plasma after an interleukin-1 injection whereas alpha(1)-inhibitor-3 decreased in plasma. In the mice plasma amyloid P was increased. The interleukin-1 receptor antagonist blocked the increase of alpha(2)-macroglobulin and plasma amyloid P in a dose dependent way while the effect on the alpha(1)-inhibitor-3 decrease was less pronounced. Interleukin-1 led to polymorphonuclear leukocyte degranulation in vivo as measured by increased cathepsin G plasma levels. The interleukin-1 receptor antagonist could influence the early phase of this degranulation.

Abstract
The contribution of each of the pro-inflammatory cytokines to specific components of the host response to infection remains unclear. Therefore, the effects of single doses of cytokines were studied in dwarf goats. The present study was carried out to investigate the effects of r.BoIL(-1beta), r.BoIL(-2) and r.BoIFN(-gamma) on plasma zinc and iron concentrations, white blood cell counts, and body temperature. The i.v. injection of r.BolL(-1beta) (1 mug kg(-1)) resulted in an immediate fever which reached peak values 45 and 180 min after injection. Compared with fever induced by r.BoIL(-1beta), that caused by r.BoIFN(-gamma) (2 mug kg(-1)) was delayed in onset. Although the biphasic fever after r.BoIFN(-gamma) was more pronounced than after r.BoIL(-1beta), the reduction in plasma trace metal concentrations was less than after r.BoIL(-1beta), r.BoIL(-2) (1 mug kg(-1) i.v.) did not induce changes in these parameters. The haematologic changes observed revealed a cell type and cytokine specific pattern. The delayed onset of the effects induced by IFN(-gamma) suggests that they may be mediated through the induction of other mediators of inflammation.

Abstract
In this study levels of prostaglandin E2 (PGE2), tumour necrosis factor (TNF) and interleukin-1 (IL-1) alpha in medium from monocyte derived macrophages (MdM) infected with Chlamydia trachomatis (L2/434/Bu or K biovars). TNF and PGE2 were found in both cases while IL-1 alpha was not detected. Both TNF and PGE2 levels were higher in the medium of the MdM infected with K biovars. TNF reached maximum levels 24 h postinfection, and then declined, while PGE2 levels increased continuously during the infection time up to 96 h post-infection. Addition of dexamethasone inhibited production of TNF and PGE2. Inhibition of PGE2 production by indomethacin resulted in increased production of TNF, while addition of PGE2 caused partial inhibition of TNF production from infected MdM.

Abstract
In this work we have studied the acute phase protein response and degranulation of polymorphonuclear leukocytes in vivo in the rat after a slow interleukin-1beta stimulation. A total dose of 1 mug, 2 mug, 4 mug and 0 mug (controls with only vehicle) of interleukin-1beta was released from osmotic minipumps over a period of 7 days. The pumps were implanted subcutaneously. A cystic formation was formed around the pumps that contained interleukin-1beta whereas no tissue reaction was seen around pumps containing only vehicle. Besides flbroblasts the cyst wall contained numerous polymorphonuclear leukocytes which were positively stained for cathespin G. alpha(2)-macroglobulin, alpha(1)-inhtbitor-3, alpha(1)-proteinase inhibitor, albumin and C3 were measured by electroimmunoassay and all showed plasma concentration patterns that were dose-dependent to the amount of interleuktn-1beta released. Fibrinogen in plasma was elevated in the control group but showed decreased plasma values with higher doses of interleukin-1beta released. All animals showed increased plasma levels of cathespin G but the lowest levels for cathespin G were seen for the highest interleukin-1beta dose released. It was clearly seen that a slow continuous release of interleukin-1beta in vivo caused an inflammatory reaction. Plasma levels for the proteins analysed all showed a similar pattern, namely an initial increase or decrease of plasma concentration followed by a tendency to normalization of plasma values. It was concluded that a long-term interleukin-1beta release could not sustain the acute phase protein response elicited by the initial interleukin-1beta release.

Abstract
Fibroblasts (Fb) from patients with sarcoidosis (SA) and
hypersensitivity pneumonitis (HP) exhibited a lower proliferative
capacity compared with Fb obtained from control (CO) and diffuse
interstitial fibrosis patients (DIF). Proliferation of Fb from SA or
lip patients was suppressed by autologous LPS-stimulated alveolar
macrophages (AM) supernatants but not by those from CO patients.
Similarly, alveolar macrophages (AM) derived supernatant, obtained
from CO, did not suppress the proliferation of SA and HP Fb. AM from
SA and HP patients secreted higher amounts of IL-1α and β
compared with controls and compared with Fb from SA and HP patients.
Steady levels of IL-1α and βmRNA were expressed in
unstimulated and stimulated cultures. Fb from SA and HP patients
could be stimulated by LPS to secrete significantly higher levels of
PGE2 than those detected in supernatants from LPS
stimulated Fb of DIF patients. Only the proliferation of Fb from SA
and HP patients was sensitive to amounts of IL-1 equivalent to those
detected in the lung of these diseases. As SA and HP are two
diseases where irreversible deterioration occurs in only 20%
of the patients, we hypothesize that mediators in the lung may
modulate Fb proliferation. IL-1 of AM origin and PGE2 of
Fb origin secreted at high levels, may be candidates for this
suppression because it was abrogated by anti IL-1β and indomethacin.

Abstract
In this study, we have demonstrated that Korean Panax ginseng (KG) significantly enhances myelopoiesis in vitro and reconstitutes bone marrow after 5-flurouracil-induced (5FU) myelosuppression in mice. KG promoted total white blood cell, lymphocyte, neutrophil and platelet counts and improved body weight, spleen weight, and thymus weight. The number of CFU-GM in bone marrow cells of mice and serum levels of IL-3 and GM-CSF were significantly improved after KG treatment. KG induced significant c-Kit, SCF and IL-1 mRNA expression in spleen. Moreover, treatment with KG led to marked improvements in 5FU-induced histopathological changes in bone marrow and spleen, and partial suppression of thymus damage. The levels of IL-3 and GM-CSF in cultured bone marrow cells after 24 h stimulation with KG were considerably increased. The mechanism underlying promotion of myelopoiesis by KG was assessed by monitoring gene expression at two time-points of 4 and 8 h. Treatment with Rg1 (0.5, 1 and 1.5 µmol) specifically enhanced c-Kit, IL-6 and TNF-α mRNA expression in cultured bone marrow cells. Our results collectively suggest that the anti-myelotoxicity activity and promotion of myelopoiesis by KG are mediated through cytokines. Moreover, the ginsenoside, Rg1, supports the role of KG in myelopoiesis to some extent.

Abstract
Interleukin-8 has long been recognized to have anti-inflammatory activity, which has been established in various models of infection, inflammation, and cancer. Several cell types express the receptor for the cytokine IL-8 and upon its recognition produce molecules that are active both locally and systemically. Many different types of cells, in particular monocytes, neutrophils, epithelial, fibroblast, endothelial, mesothelial, and tumor cells, secrete IL-8. Increased expression of IL-8 and/or its receptors has been characterized in many chronic inflammatory conditions, including psoriasis, ARDS, COPD, and RA as well as many cancers, and its upregulation often correlates with disease activity. IL-8 constitutes the CXC class of chemokines, a potent chemoattractant and activator of neutrophils and other immune cells. It is a proangiogenic cytokine that is overexpressed in many human cancers. Therefore, inhibiting the effects of IL-8 signaling may be a significant therapeutic intervention.

Abstract
BACKGROUND Severe trauma, including burns, triggers a systemic response that significantly impacts on the liver, which plays a key role in the metabolic and immune responses aimed at restoring homeostasis. While many of these changes are likely regulated at the gene expression level, there is a need to better understand the dynamics and expression patterns of burn injury-induced genes in order to identify potential regulatory targets in the liver. Herein we characterized the response within the first 24 h in a standard animal model of burn injury using a time series of microarray gene expression data. METHODS Rats were subjected to a full thickness dorsal scald burn injury covering 20% of their total body surface area while under general anesthesia. Animals were saline resuscitated and sacrificed at defined time points (0, 2, 4, 8, 16, and 24 h). Liver tissues were explanted and analyzed for their gene expression profiles using microarray technology. Sham controls consisted of animals handled similarly but not burned. After identifying differentially expressed probe sets between sham and burn conditions over time, the concatenated data sets corresponding to these differentially expressed probe sets in burn and sham groups were combined and analyzed using a "consensus clustering" approach. RESULTS The clustering method of expression data identified 621 burn-responsive probe sets in four different co-expressed clusters. Functional characterization revealed that these four clusters are mainly associated with pro-inflammatory response, anti-inflammatory response, lipid biosynthesis, and insulin-regulated metabolism. Cluster 1 pro-inflammatory response is rapidly up-regulated (within the first 2 h) following burn injury, while Cluster 2 anti-inflammatory response is activated later on (around 8 h post-burn). Cluster 3 lipid biosynthesis is down-regulated rapidly following burn, possibly indicating a shift in the utilization of energy sources to produce acute phase proteins, which serve the anti-inflammatory response. Cluster 4 insulin-regulated metabolism was down-regulated late in the observation window (around 16 h post-burn), which suggests a potential mechanism to explain the onset of hypermetabolism, a delayed but well-known response that is characteristic of severe burns and trauma with potential adverse outcome. CONCLUSIONS Simultaneous analysis and comparison of gene expression profiles for both burn and sham control groups provided a more accurate estimation of the activation time, expression patterns, and characteristics of a certain burn-induced response based on which the cause-effect relationships among responses were revealed.

Abstract
The varied reactions of the host to infection, inflammation, or trauma are collectively known as the acute-phase response and encompass a wide range of pathophysiological responses such as pyrexia, leukocytosis, hormone alterations, and muscle protein depletion combining to minimize tissue damage while enhancing the repair process. The mechanism for stimulation of hepatic production of acute-phase proteins is by proinflammatory cytokines. The functions of positive acute-phase proteins (APP) are regarded as important in optimization and trapping of microorganism and their products, in activating the complement system, in binding cellular remnants like nuclear fractions, in neutralizing enzymes, scavenging free hemoglobin and radicals, and in modulating the host's immune response. APP can be used as diagnostic tool in many diseases like bovine respiratory syncytial virus, prostate cancer, bronchopneumonia, multiple myeloma, mastitis, Streptococcus suis infection, starvation, or lymphatic neoplasia. Thus, acute-phase proteins may provide an alternative means of monitoring animal health.
