Nutrition additionally serves as a vital component in maintaining bodily homeostasis. Macronutrients, micronutrients, and specific dietary habits exert profound effects on the immune system. The complex interactions of the immune system reflect a multifaceted, integrated epithelial and immune cell-mediated regulatory system. While several factors can influence the intestinal mucosal barrier and its pro- and anti-inflammatory processes, such as myeloid cell, regulatory T cell (Treg), or intraepithelial lymphocyte populations, there is growing evidence that macronutrients play an essential role in regulating its function. Herein this is a review of the peer-reviewed literature pertaining to dietary effects on mucosal integrity, including intraepithelial lymphocyte populations and immune function. This review is intended to explore the underlying mechanisms by which macronutrients impact and modulate the mucosal immune system.","PeriodicalId":93552,"journal":{"name":"Exploration of immunology","volume":"259 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140420798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diagnostic challenges arise due to their diverse manifestations, potential long-term consequences, and the absence of specific serological markers, necessitating a multidisciplinary approach combining clinical evaluation, audiological assessments, and imaging techniques. Various autoimmune disorders, including systemic lupus erythematosus, rheumatoid arthritis, and Sjogren’s syndrome, have been implicated in immune-mediated damage to auditory structures, resulting in inner ear dysfunction. Inflammatory processes in autoinflammatory diseases like Cogan’s syndrome and relapsing polychondritis can also affect the inner ear. While the exact mechanisms of inner ear involvement in these conditions are still being studied, immune-mediated inflammation, damage to auditory structures, and vascular involvement play significant roles in auditory impairments. Treatment strategies primarily focus on immunomodulation and inflammation control using corticosteroids, immunosuppressants, and targeted biologic agents to ameliorate symptoms and preserve hearing function. Hearing aids and cochlear implants may be also considered for severe hearing loss. Individualized approaches are necessary due to patient response heterogeneity. This review provides a concise overview of key autoimmune and autoinflammatory diseases impacting the inner ear, highlighting clinical manifestations, diagnostics, pathophysiology, and treatment options. Early recognition and appropriate management are crucial for optimizing patient outcomes. Further research is needed to understand underlying mechanisms and identify novel therapeutic targets. Collaboration between otolaryngologists, rheumatologists, and immunologists is crucial for improving the quality of life in these complex conditions.","PeriodicalId":93552,"journal":{"name":"Exploration of immunology","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140441945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Signal-transducing adaptor protein-2 (STAP-2) is an adaptor protein that contains typical domains such as the pleckstrin homology (PH) domain, Src homology domain, and a proline-rich region from the N-terminal region. In T cells, STAP-2 positively regulates T cell receptor (TCR)-mediated signaling by associating with CD3ζ immunoreceptor tyrosine-based activation motifs (ITAMs) and lymphocyte-specific protein tyrosine kinase (LCK). Therefore, a peptide that inhibits the interaction between STAP-2 and CD3ζ ITAMs is likely to suppress TCR-mediated T cell activation, as well as T cell-mediated diseases. As expected, the peptide successfully inhibited the STAP-2/CD3ζ ITAM interaction and suppressed TCR-mediated signaling, cell proliferation, and interleukin (IL)-2 production in human/murine T cells. Furthermore, this inhibitor suppressed the pathogenesis of experimental autoimmune encephalomyelitis (EAE), which is widely recognized as a mouse model of multiple sclerosis, via the downregulation of T cell activation and infiltration of T helper (Th) 1/Th17 cells. These results suggest a new strategy for the treatment of multiple sclerosis and other immune diseases.","PeriodicalId":93552,"journal":{"name":"Exploration of immunology","volume":"54 s51","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139150310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
