Abstract
Food allergy (FA) is a common immune disorder that involves dysfunctional immune regulation. More remedies for restoring immune regulation are necessary. Semaphorin 3 A (Sema3a) is a secreted protein of the semaphorin family, which plays a role in immune responses at all stages. The objective of this study is to gain an understanding of how Sema3a can restore the immune regulatory abilities of type 1 regulatory T cells (Tr1 cells). In this study, blood samples were taken from patients with FA. Tr1 cells were purified from blood samples using flow cytometry cell sorting, using LAG3 and CD49b as surface markers. RNA sequencing was employed to examine the characteristics of Tr1 cells. We observed an exaggerated increase in ER stress in peripheral Tr1 cells of FA patients. Enforced expression of spliced X-box protein-1 (XBP1s, one of the key molecules in ER stress) resulted in suppression of interleukin (IL)-10 expression in CD4+ T cells. Eukaryotic initiation factor 2a (eIF2a) mediated the effects of XBP1 on suppressing IL-10 expression in Tr1 cells. The use of Sema3a resulted in a decrease in ER stress, and an increase in IL-10 expression in Tr1 cells of FA patients. Sema3a administration reduced experimental FA by increasing the number of Tr1 cells. In conclusion, IL-10 expression in Tr1 cells is disturbed by ER stress. Sema3a treatment restores the expression of IL-10 and the immunosuppressive capability of Tr1 cells.

Heliyon 2024; 10:e22924. [PMID: 38148815 PMCID: PMC10750067 DOI: 10.1016/j.heliyon.2023.e22924] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Revised: 11/18/2023] [Accepted: 11/22/2023] [Indexed: 12/28/2023] Open
Abstract
Background Allergic rhinitis (AR) is a common immunoglobulin (Ig) E-mediated disease. This study aimed to evaluate the gene expression levels of class 4 semaphorins and their receptors in AR patients before and after treatment with budesonide and fexofenadine (B/F) compared to fluticasone propionate and fexofenadine (FP/F). Methods In this study, 29 AR patients (age 34.4 ± 1.2 years, 18 men and 11 women) were treated with B/F, and 24 AR patients (age 32.8 ± 1.9 years, 15 men and 9 women) were treated with FP/F for one month. Before and after treatment, peripheral blood samples were taken from patients. The expression levels of SEMA4A, SEMA4C, SEMA4D, Plexin-B2, and Plexin-D1 genes were measured using the qPCR method. In addition, the serum levels of IgE were measured using an enzyme-linked immunosorbent assay (ELISA). Results The expression levels of SEMA4A (P = 0.011), 4C (P = 0.017), Plexin-B2 (P = 0.0005), and Plexin-D1 (P = 0.008) remarkably increased in AR patients treated with B/F. Our results show a significant reduction in the gene expression levels of SEMA4A (P = 0.002), 4C (P = 0.014), 4D (P = 0.003), Plexin-B2 (P = 0.033), and Plexin-D1 (P = 0.035) after treatment with FP/F. The serum levels of IgE increased in FP/F treated group (P = 0.017) and conversely decreased in the treated group with B/F (P = 0.019). Moreover, the percentages of eosinophils were reduced in both FP/F and B/F groups (P = 0.015 and P = 0.0001, respectively). Conclusion In conclusion, concomitant use of fexofenadine and fluticasone propionate reduced SEMA4A, 4C, 4D, Plexin-B2, and Plexin-D1, while the SEMA4A, 4C, Plexin-B2, and Plexin-D1 gene expression levels were increased in the patient group treated with B/F.

Abstract
Semaphorins were originally identified as guidance molecules in neural development. However, accumulating evidence indicates that 'immune semaphorins' are critically involved in regulating immune cell activation, differentiation, mobility and migration. Semaphorins are also intimately associated with the pathogenesis of allergic diseases including asthma, allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and eosinophilic chronic rhinosinusitis. Interestingly, reflecting their function in positive or negative regulation of immune cells, levels of some semaphorins are increased while others are decreased in patients with allergic diseases. This review presents the pathogenic functions of immune semaphorins in allergic inflammation and discusses the potential use of these molecules as therapeutic targets for allergic diseases.

Abstract
Semaphorins have recently been recognized as crucial modulators of immune responses. In the pathogenesis of COVID-19, the activation of immune responses is the key factor in the development of severe disease. This study aimed to determine the association of serum semaphorin concentrations with COVID-19 severity and outcomes. Serum semaphorin concentrations (SEMA3A, -3C, -3F, -4D, -7A) were measured in 80 hospitalized adult patients with COVID-19 (moderate (n = 24), severe (n = 32), critical, (n = 24)) and 40 healthy controls. While SEMA3C, SEMA3F and SEMA7A serum concentrations were significantly higher in patients with COVID-19, SEMA3A was significantly lower. Furthermore, SEMA3A and SEMA3C decreased with COVID-19 severity, while SEMA3F and SEMA7A increased. SEMA4D showed no correlation with disease severity. Serum semaphorin levels show better predictive values than CRP, IL-6 and LDH for differentiating critical from moderate/severe COVID-19. SEMA3F and SEMA7A serum concentrations were associated with the time to recovery, requirement of invasive mechanical ventilation, development of pulmonary thrombosis and nosocomial infections, as well as with in-hospital mortality. In conclusion, we provide the first evidence that SEMA3A, SEMA3C, SEMA3F and SEMA7A can be considered as new biomarkers of COVID-19 severity.

Abstract
Emerging evidence suggests that neural activity contributes to tumor initiation and its acquisition of metastatic properties. More specifically, it has been reported that the sympathetic nervous system regulates tumor angiogenesis, tumor growth, and metastasis. The function of the sympathetic nervous system in primary tumors has been gradually elucidated. However, its functions in pre-metastatic environments and/or the preparation of metastatic environments far from the primary sites are still unknown. To investigate the role of the sympathetic nervous system in pre-metastatic environments, we performed chemical sympathectomy using 6-OHDA in mice and observed a decrease in lung metastasis by attenuating the recruitment of myeloid-derived suppressor cells. Furthermore, we note that neuro-immune cell interactions could be observed in tumor-bearing mouse lungs in conjunction with the decreased expression of Sema3A. These data indicate that the sympathetic nervous system contributes to the preparation of pre-metastatic microenvironments in the lungs, which are mediated by neuro-immune cell interactions.

Abstract
Peptic ulcer disease is a frequent clinical problem with potentially serious complications such as bleeding or perforation. A decisive factor in the pathogenesis of peptic ulcers is gastric acid, the secretion of which is controlled by the hormone gastrin released from gastric G cells. However, the molecular mechanisms regulating gastrin plasma concentrations are poorly understood. Here, we identified a semaphorin-plexin signaling pathway that operates in gastric G cells to inhibit gastrin expression on a transcriptional level, thereby limiting food-stimulated gastrin release and gastric acid secretion. Using a systematic siRNA screening approach combined with biochemical, cell biology, and in vivo mouse experiments, we found that the RasGAP protein Rasal1 is a central mediator of plexin signal transduction, which suppresses gastrin expression through inactivation of the small GTPase R-Ras. Moreover, we show that Rasal1 is pathophysiologically relevant for the pathogenesis of peptic ulcers induced by nonsteroidal anti-inflammatory drugs (NSAIDs), a main risk factor of peptic ulcers in humans. Last, we show that application of recombinant semaphorin 4D alleviates peptic ulcer disease in mice in vivo, demonstrating that this signaling pathway can be harnessed pharmacologically. This study unravels a mode of G cell regulation that is functionally important in gastric homeostasis and disease.

Abstract
Semaphorin 3A is a secreted glycoprotein, which was originally identified as axon guidance factor in the neuronal system, but it also possesses immunoregulatory properties. Here, the effect of semaphorin 3A on T-lymphocytes, myeloid dendritic cells and macrophages is systematically analyzed on the bases of all publications available in the literature for 20 years. Expression of semaphorin 3A receptors – neuropilin-1 and plexins A – in these cells is described in details. The data obtained on human and murine cells is described comparatively. A comprehensive overview of the interaction of semaphorin 3A with mononuclear phagocyte system is presented for the first time. Semaphorin 3A signaling mostly results in changes of the cytoskeletal machinery and cellular morphology that regulate pathways involved in migration, adhesion, and cell–cell cooperation of immune cells. Accumulating evidence indicates that this factor is crucially involved in various phases of immune responses, including initiation phase, antigen presentation, effector T cell function, inflammation phase, macrophage activation, and polarization. In recent years, interest in this field has increased significantly because semaphorin 3A is associated with many human diseases and therefore can be used as a target for their treatment. Its involvement in the immune responses is important to study, because semaphorin 3A and its receptors turn to be a promising new therapeutic tools to be applied in many autoimmune, allergic, and oncology diseases.

Abstract
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by neuronal degeneration and inflammation in the nerves. G-CSF is a 19.6-kDa hematopoietic growth factor which is essential for the proliferation and differentiation of granulocyte hematopoietic progenitors. G-CSF exerts neuroprotective activities by induction of neuronal regeneration, inhibition of neuronal apoptosis, mobilization of Hematopoietic stem cells (HSCs), regulation of pro and anti-inflammatory cytokines, and activation of angiogenesis. Pre-clinical studies have shown significant efficacy of G-CSF therapy in mSOD1G93A mice models. G-CSF treatments were able to increase the survival of mice. However, clinical studies on ALS patients failed to clone pre-clinical results. Considering the potential role of G-CSF in nervous system regeneration, this study aimed to comprehensively review the clinical and pre-clinical studies addressing G-CSF in ALS treatment.

Abstract
Axon guidance proteins are essential for axonal pathfinding during development. In adulthood, they have been described as pleiotropic proteins with multiple roles in different organs and tissues. While most studies on the roles of these proteins in the cornea have been performed on the Semaphorin family members, with few reports on Netrins or Ephrins, their function in corneal epithelium wound healing and functional nerve regeneration is largely unknown. Here, we studied the expression of ligands belonging to three distinct axon guidance families (Semaphorins, Ephrins, and Netrins) and their most commonly associated receptors in the cornea and trigeminal ganglia (TG) using immunofluorescence staining and RT-qPCR. We also evaluated how their expression recovers after corneal epithelium injury. We found that all ligands studied (Sema3A, Sema3F, EphrinB1, EphrinB2, Netrin-1, and Netrin-4) are abundantly expressed in both the TG and corneal epithelium. Similarly, their receptors (Neuropilin-1, Neuropilin-2, PlexinA1, PlexinA3, EphB2, EphB4, Neogenin, UNC5H1 and DCC) are also expressed in both tissues. Upon corneal epithelium injury, quick recovery of both ligands and receptors was observed at the protein and gene expression levels. While the timing and expression levels vary among these proteins, in general, most of them remained upregulated for several weeks after injury. We propose that the initial protein expression recovery may be related to corneal epithelium recovery since Sema3A, EphrinB2 and Netrin-4 accelerated corneal epithelial cells wound healing. The sustained high expression levels may be functionally related to nerve regeneration and/or patterning. Whilst further studies are required to test this hypothesis, this work contributes to unraveling their function in normal and injured cornea.

Abstract
Periodontitis (PD), also known as gum disease, is a condition causing inflammatory bone resorption and tooth loss. Regulatory T cells (Tregs) and regulatory B cells (Bregs) are vital in controlling the immune response and hence play a role in infections and peripheral tolerance adjustment. These cells have immunosuppressive and tissue-repairing capabilities that are important for periodontal health; however, in inflammatory circumstances, Tregs may become unstable and dysfunctional, accelerating tissue deterioration. In recent years, Regulatory cell-mediated immunotherapy has been shown to be effective in many inflammatory diseases. Considering the roles of Tregs and Bregs in shaping immune responses, this study aimed to review the published articles in this field to provide a comprehensive view of the existing knowledge about the role of regulatory T and B cells, as well as their therapeutic applications in PD.

Abstract
Ovarian cancer (OC) is the most lethal tumor of the female reproductive tract and one of the most prevalent causes of death among female cancer patients. The absence of suitable procedures for early diagnosis, chemoresistance, and limited surgical debulking are all contributing to poor survival in patients. Despite aggressive treatments, the majority of patients have a recurrence within 16-22 months. Inflammasomes are multimeric protein complexes that play a major role in the innate immune system and inflammation. The overexpression of inflammasome-related pathways, including NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3), Absent in melanoma 2 (AIM2), caspase-1, and Interleukin (IL)-1 have been reported in OC patients and in vitro cell lines. Therefore, inflammasome-related genes and protein might have a role in OC pathogenesis. Considering the potential relationship between inflammasome and OC, this study aimed to provide a literature-based review to explain the role of inflammasome and inflammation in cancer progression in OC.

Abstract
Osteopontin (OPN) is a multifunctional cytokine and adhesion molecule, as well as an unusual regulator for both innate and adaptive immune responses. Several immune cells can produce OPN, including dendritic cells (DCs), macrophages, and T lymphocytes. OPN expression is reported to be increased in a wide range of disorders, including autoimmunity, cancer, and allergy. The overexpression of OPN in several autoimmune disorders, such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), multiple sclerosis (MS), Type 1 diabetes (T1D), inflammatory bowel disease (IBD), Sjögren's, and myasthenia gravis, have been shown to be correlated with disease severity. Regarding the important regulatory roles of OPN in the immune system, this study aimed to review the role of this molecule in autoimmune disorders and to provide a complete view of the current knowledge in this field.

Abstract
Semaphorin-3A (Sema-3A), a secreted member of the semaphorin family, is well known for playing regulatory functions at all stages of the immune response. Sema-3A transduces signals by binding to its cognate receptors, namely, class A plexins (Plxns A1 to A4) and neuropilin-1 (Nrp-1). The downstream diverse signaling pathways induced by connecting Sema-3A to its receptors were found to be involved in the pathogenesis of different immunological disorders, ranging from cancer to autoimmunity and allergies. Recent studies have demonstrated that Sema-3A expression is diminished in the murine models and patients with allergic rhinitis (AR; a chronic inflammatory disorder of the nasal mucosa), suggesting the involvement of Sema-3A in AR pathogenesis. Investigations also revealed that treatment of these mice with exogenous Sema-3A protein alleviates the clinical symptom scores of AR, thereby compensating for the reduced expression of Sema-3A in AR. Indeed, Sema-3A treatment could suppress allergic responses in AR via inhibiting Th2/Th17 responses and boosting Th1/Treg responses. Also, Sema-3A could diminish dendritic cell (DC) maturation and T cell proliferation. Since it is implicated in the pathogenesis of AR; thus, Sema-3A turns to be a promising tool of therapy to be studied and utilized in this disease. This review intends to highlight the recent evidence on the role of Sema-3A in AR pathogenesis and summarizes the recent findings regarding the expression status of Sema-3A, as well as its therapeutic potential for treating this disease. HIGHLIGHTS: Sema-3A plays regulatory functions at all stages of the immune response. Sema-3A receptors are the class A plexins (A1-A4) and neuropilin-1 (Nrp-1). Sema-3A expression is reduced in murine models and patients with allergic rhinitis. Connecting Sema-3A to Nrp-1 increases Foxp3 expression in Treg cells. Injecting Sema-3A protein exerts therapeutic effects in mouse models of allergic diseases. Sema-3A shows promise as a therapeutic tool for the treatment of allergic rhinitis.

Abstract
One of the most common diabetic microvascular complications is diabetic neuropathy (DN). Immune cell infiltration in the peripheral nerve system (PNS), myelin loss, Schwann cell death, and axonal damage are all hallmarks of DN, which is currently believed to be a chronic inflammatory disease. Toll-like receptors (TLRs) are found in various types of nervous system cells, including Schwann cells, microglia, oligodendrocytes, astrocytes, and neurons. Proinflammatory mediators released at the end of TLR signal transduction can trigger an inflammatory response involving the nervous system. Studies on the association between TLRs and DN began as early as 2004. Since then, several studies have been conducted to assess the involvement of TLRs in the pathogenesis of DN. The focus of this review is to give a complete summary of the researches that have been done in this context, as well as an overview of the role of TLRs and their therapeutic applications in DN.

Abstract
OBJECTIVE To explore the association of the Notch1/Jagged1 pathway with the homing of mesenchymal stem cells (BMSCs) to regulate Th1/Th2 drift in asthma. METHODS Twenty SD rats were randomly divided into normal control group, model group, BMSC transplantation group, and BMSC+Notch inhibitor group. Ovalbumin sensitization was used to establish rat models of asthma, and BMSCs were transplanted via the tail vein. The pathology of the lung tissue was examined with HE staining, and the contents of interleukin (IL)-5, IL-13, and interferon-γ (IFN-γ) in lung tissue homogenate were determined with enzyme-linked immunosorbent assay. The expressions of Notch1 and Jagged1 mRNA were detected with RT-PCR, and CXCR4 expression in the bronchial epithelial cells was examined using immunofluorescence staining; Western blotting was used to detect the protein expressions of T-bet, GATA-3, Notch1, and Jagged1 in the lung tissue. RESULTS Compared with those in the control group, the expressions of IFN-γ and T-bet proteins decreased significantly and the pulmonary expressions of IL-5, IL-13, and GATA-3 proteins as well as Notch1 and Jagged1 mRNA and protein expressions all increased significantly in the model group (P < 0.05 or 0.01). Compared with those in the model group, CXCR4, IFN-γ, and T-bet protein expressions in BMSC group and BMSCs+Notch inhibitor group all increased significantly, and Notch1 and Jagged1 protein expressions in BMSCs group and IL-5, IL-13, Notch1, and Jagged1 mRNA and protein expressions in BMSCs + Notch inhibitor group all decreased significantly (P < 0.05 or 0.01). The expressions of CXCR4 and IFN-γ were significantly higher and the expressions of IL-13 and Notch1 mRNA were significantly lower in BMSCs+Notch inhibitor group than in BMSC group (P < 0.05). CONCLUSION In asthmatic rats, the homing of the BMSCs to the lung tissue has a regulatory effect on Th1/Th2 drift, and the Notch1/Jagged1 pathway may participate in the homing of the BMSCs.

Abstract
Allergy, IgE-mediated inflammatory disorders including allergic rhinitis, asthma, and conjunctivitis, affects billions of people worldwide. Conventional means of allergy management include allergen avoidance, pharmacotherapy, and emerging therapies. Among them, chemotherapeutant intake via oral, intravenous, and intranasal routes is always the most common mean. Although current pharmacotherapy exhibit splendid anti-allergic effects, short in situ retention, low bioavailability, and systemic side effects are inevitable. Nowadays, nanoplatforms have provided alternative therapeutic options to obviate the existing weakness via enhancing the solubility of hydrophobic therapeutic agents, achieving in situ drug accumulation, exhibiting controlled and long-time drug release at lesion areas, and providing multi-functional therapeutic strategies. Herein, we highlight the clinical therapeutic strategies and deal with characteristics of the nanoplatform design in allergy interventions via intratracheal, gastrointestinal, intravenous, and ocular paths. The promising therapeutic utilization in a variety of allergic disorders is discussed, and recent perspectives on the feasible advances of nanoplatforms in allergy management are also exploited.

Abstract
BACKGROUND The extracellular matrix of the PNS/CNS is unusual in that it is dominated by glycosaminoglycans, especially hyaluronan, whose space filling and hydrating properties make essential contributions to the functional properties of this tissue. Hyaluronan has a relatively simple structure but its space-filling properties ensure micro-compartments are maintained in the brain ultrastructure, ensuring ionic niches and gradients are maintained for optimal cellular function. Hyaluronan has cell-instructive, anti-inflammatory properties and forms macro-molecular aggregates with the lectican CS-proteoglycans, forming dense protective perineuronal net structures that provide neural and synaptic plasticity and support cognitive learning. AIMS To highlight the central nervous system/peripheral nervous system (CNS/PNS) and its diverse extracellular and cell-associated proteoglycans that have cell-instructive properties regulating neural repair processes and functional recovery through interactions with cell adhesive molecules, receptors and neuroregulatory proteins. Despite a general lack of stabilising fibrillar collagenous and elastic structures in the CNS/PNS, a sophisticated dynamic extracellular matrix is nevertheless important in tissue form and function. CONCLUSIONS This review provides examples of the sophistication of the CNS/PNS extracellular matrix, showing how it maintains homeostasis and regulates neural repair and regeneration.

Abstract
OBJECTIVE To observe the effect of Yanghe Pingchuan (YHPC) granule on miR-139-5p, Notch1/Hes1 pathway and homing of bone marrow-derived mesenchymal stem cells (BMSCs) in asthmatic rats. METHODS Fifty SD rats were randomized divided into normal control (NC) group, asthmatic model group, BMSCs transplantation group, BMSCs + dexamethasone (0.0625 mg/kg daily) group, and BMSCs+YHPC granule (3.5 g/kg daily) group. In all but the normal control group, asthmatic rat models were established by ovalbumin challenge, and BMSCs (1×106/mL) transplantation via the tail vein was performed in the latter 3 groups on last day of ovalbumin challenge. In all the groups, lung pathologies of the rats were evaluated using HE staining after the treatments. Flow cytometry was employed to detect pulmonary expression of CXCR4 protein, and ELISA was used to determine the expressions of interferon-γ (IFN-γ) and interleukin-4 (IL-4) in the lung tissue. The expressions of CXCR4, Notch1 and Hes1 in bronchial epithelial cells was examined using immunofluorescence assay. RT-PCR was used to detect the expressions of miR-139-5p, Notch1, Jagged1, RBP-J and Hes1 mRNAs, and the protein expressions of Notch1, Jagged1 and Hes1 were detected with Western blotting. RESULTS Compared with the normal control rats, the asthmatic rats exhibited significantly increased expressions of CXCR4, IL-4, Notch1, Jagged1, RBP-J, and Hes1 mRNA and Notch1, Jagged1, and Hes1 proteins and lowered expressions of INF-γ mRNA and miR-139-5p in the lung tissues (P < 0.05 or 0.01). Compared with those in the asthmatic model group, the mRNA expressions of CXCR4, IFN-γ, and miR-139-5p increased and the expressions of IL-4, Notch1, Jagged1, RBP-J, and Hes1 mRNA and Notch1, Jagged1, and Hes1 proteins decreased significantly in the 3 groups with BMSCs transplantation (P < 0.05 or 0.01). The rats in BMSCs+YHPC granule group showed significantly higher CXCR4, IFN-γ, and miR-139-5p mRNA expressions and lower IL-4 and Notch1 mRNA expressions than those in BMSCs transplantation group (P < 0.05). CONCLUSIONS YHPC granule can enhance the inhibitory effect of BMSCs homing on Th2 inflammatory response in asthmatic rats by up-regulating miR-139-5p and down-regulating Notch1/Hes1 pathway.
