Article Abstract
The role of interleukin (IL)-17 and the IL-17-producing T helper (Th)17 cells in cancer has recently become the focus of extensive investigation. An expanding body of literature implicates Th17 cells and their hallmark cytokine in both pro- and anti-tumourigenic processes. In this review we describe their biological activities and outline the reciprocal interactions between Th17 cells and other cells of the immune system. We also discuss the evidence regarding their dual role in the tumour microenvironment. An understanding of the processes that regulate the pro- or anti-tumour activities of Th17 cell and IL-17 will allow the development of more effective means for cancer immunotherapy.

Th17 cells are activated by STAT3 factors in the nucleus, and these factors are correlated with the pathologic progression of rheumatoid arthritis (RA). Recent studies have demonstrated the presence of STAT3 in mitochondria, but its function is unclear. We investigated the novel role of mitochondrial STAT3 (mitoSTAT3) in Th17 cells and fibroblast-like synoviocytes (FLSs) and analyzed the correlation of mitoSTAT3 with RA.

This study attempted to explore the molecular mechanism of Epimedium herb (EH) on rheumatoid arthritis (RA) treatment. We employed network pharmacology, molecular docking, and HPLC analysis to investigate the molecular mechanisms underlying the efficacy of EH in treating RA. To assess the efficacy of EH intervention, RA fibroblast-like synoviocytes (RA-FLS) and collagen-induced arthritis (CIA) mouse models were utilized.

Introduction/aims: Tofacitinib, a first-generation Janus kinase (JAK) 1/3 inhibitor, is commonly used for treating ulcerative colitis and rheumatoid arthritis. However, its role in myasthenia gravis (MG) remains unclear. This study aimed to evaluate the immunomodulatory effects of tofacitinib on experimental autoimmune myasthenia gravis (EAMG) and peripheral blood mononuclear cells (PBMCs) from patients with MG.

Multiple genetic associations suggest a causative relationship between Th17-related genes coding for proteins, such as IL-17A, IL-23 and STAT3, and psoriasis. Further support for this link comes from the findings that neutralizing antibodies directed against IL-17A, IL-17RA and IL-23 are efficacious in diseases like psoriasis, psoriatic arthritis and ankylosing spondylitis. RORγt is a centrally positioned transcription factor driving Th17 polarization and cytokine secretion and modulation of RORγt may thus provide additional benefit to patients.
