IL-21 is produced by activated T follicular helper cells (Tfh), Th17 cells, and NKT cells. Tfh-derived IL-21 plays an important role in the development of humoral immunity through its autocrine effects on the Tfh cell and paracrine effects on immunoglobulin affinity maturation, plasma cell differentiation, and B cell memory responses. IL-21 protein regulates several aspects of T cell function. It co-stimulates the activation, proliferation, and survival of CD8+ T cells and NKT cells and promotes Th17 cell polarization. IL-21 blocks the generation of regulatory T cells and their suppressive effects on CD4+ T cells. In addition to its role in T cell biology, IL-21 also plays a critical role in B cell activation, proliferation, differentiation, and apoptosis. It is also required for the migration of dendritic cells to draining lymph nodes. And IL-21 suppresses cutaneous hypersensitivity reactions by limiting allergen-specific IgE production and mast cell degranulation. In the autoimmune disease Systemic lupus erythematosus (SLE), a link between IL-21 and SLE disease susceptibility and progression was recently reported.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Elabscience Biotechnology","offers":[{"title":"100μg","offer_id":40796366274618,"sku":"PKSM041469-100","price":874.95,"currency_code":"USD","in_stock":true},{"title":"20μg","offer_id":40796366307386,"sku":"PKSM041469-20","price":296.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7785\/files\/recombinant-mouse-il-21-protein-n-his-active-100-g-elabscience-biotechnology-cell-assays-22691916677178.jpg?v=1752497110","url":"https:\/\/www.msesupplies.com\/en-de\/products\/recombinant-mouse-il-21-protein-n-his-active","provider":"MSE Supplies","version":"1.0","type":"link"}
