26818544 HCV infection increased the frequency of CD4+CXCR5+ T cells and decreased the frequency of CD27+IgG+ B cells. CD4+CXCR5+ T cells activated CD27+IgG+ B cells via the secretion of IL-21.
26802931 IL-21 expression is promoted by MEKK4 in malignant T cells and is associated with progression risk in cutaneous T-cell lymphoma
26742440 IL-21 protein was higher in serum and mRNA and protein were higher in disc tissue of patients with lumbar disc herniation compared to controls.
26646950 The results suggest that IL-21 promotes migration and invasion of Rheumatoid arthritis-Fibroblast-like synoviocytes. Therefore, therapeutic strategies targeting IL-21 might be effective for the treatment of Rheumatoid arthritis.
26646149 all Ifng+ T cells produced IL-21, but only a small percentage of highly proliferative Ifng+ T cells maintained a T-bethi phenotype
26566861 IL-12 induced the generation of IL-21- and IFN-gamma-co-expressing poly-functional CD4+ T cells from human naive CD4+ T cells.
26535636 the minor allele T of both rs6822844 (T vs G, OR = 0.72, 95%CI = 0.67-0.78, P < 0.001) and rs6840978 (T vs C, OR = 0.76, 95%CI = 0.71-0.83, P < 0.001) in IL21 significantly decreased the risk of celiac disease (Meta-Analysis)
26482544 results suggest that IL-21 could promote rheumatoid arthritis fibroblast-like synoviocytes proliferation and production of proinflammatory cytokines
26466984 IL-21 exerts major effects on B-cell activation and differentiation or apoptosis during humoral immune responses, and also affects different subtypes of T cells. (Review)
26416419 CD3(+)TCRvbeta11(+) NKT cells from a local site of M. tuberculosis infection produce IL-21, express CXCR5 and CD40L, help B cells to secrete IgG and IgA, and may participate in local immune responses against M. tuberculosis infection.
