conclusions the inhibition of tregs is a novel therapeutic approach to cure chronically hbv infected patients. however, further studies are needed to investigate the safety and efficacy of this approach. results considering the increased levels of regulatory cytokines and also regulatory t cells (tregs) during chb, it seems that these cells are deeply involved in chb infection. the inhibition o...

multiple sclerosis (ms) is an inflammatory demyelinating and neurodegenerative disorder of  the  central  nervous  system (cns), which mainly affects  young adults. activated t lymphocytes promote the neuro-inflammatory cascade of ms by secreting pro-inflammatory cytokines and play a significant role in its pathogenesis. t  lymphocytes may trigger the inflammation, which in turn leads to axonal...

objective(s): this study aimed to investigate the role and the possible mechanisms involved in the immunoregulation of experimental periodontitis by th17/treg. materials and methods: experimental periodontitis was established by silk thread ligation with porphyromonasgingivalis daubing in the bilateral maxillary second molar of male sprague-dawley (sd) rats. alveolar bones were scanned by micro...

human wharton’s jelly-derived mesenchymal stem cells (hwj-mscs) are easily available cells without transplant rejection problems or ethical concerns compared to bone-marrow-derived mscs for prospective clinical applications. these cells display immunosuppressive properties and may be able to play an important role in autoimmune disorders. regulatory t-cells (treg) are important to prevent autoi...

Objective(s): Multiple sclerosis (MS) is considered as a chronic type of an inflammatory disease characterized by loss of myelin of CNS.Recent evidence indicates that Interleukin 17 (IL-17)-producing T helper cells (Th17 cells) population are increased and regulatory T cells (Treg cells) are decreased in MS. Despite extensive research in understanding the mechanism of Th17 and Treg differentiat...

Regulatory T cells (Treg) restrain skin inflammation under healthy conditions and after immune challenges. Adult human contains 20 billion 1-3 are highly suppressive FOXP3+ Treg. We observed inflammatory eruptions in CTCL patients treated with alemtuzumab (αCD52), an antibody that purges recirculating from skin. αCD52-induced eczematous dermatitis had 5-fold lower Treg numbers (p<0.0001) 7-fold...

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease that is characterized by T-cells imbalance. There are ongoing controversies about the role of specific T-helper cell subsets and their cytokines. The study aimed to confirm the disturbance of Th17/Treg ratio in SLE patients. Methods: Subjects were SLE patients who met the American College of Rheumatology 1997 criteria. Dis...

We previously reported that Foxp3+CD4+ regulatory (Treg) cells expressing CTLA-4 on the cell surface are enriched in tumor microenvironment of human head and neck squamous carcinoma (HNSCC). Since is a key molecule to suppress dendritic (DCs), we investigated DCs HNSCC. Using scRNA-seq database, found HNSCC contained DC1, DC2 third DC subset expressed LAMP3 highly with migratory mature phenotyp...

Primary immune thrombocytopenia (ITP) is an autoimmune heterogeneous disorder. T regulatory cells (Treg), play important role in the pathogenesis of disease. Numerical and functional disorders Treg were both demonstrated ITP. Thymocyte output decrease instability contributed to lower count cells. Several deregulatory defects further led disease's onset. Restoring might have a therapeutic effect...
