IL-21 may promote the transition between innate and adaptive immunity. IL-21 may have a role in proliferation and maturation of natural killer cells in synergy with IL15. IL-21 stimulates interferon gamma production in T-cells and natural killer cells by synergy with IL15 and IL18. Dysregulation of IL-21 has a role in multiple immune-mediated diseases including lupus, psoriasis and chronic inflammatory diseases.","brand":"ELK Biotechnology","offers":[{"title":"10ug","offer_id":50413951123736,"sku":"EPT303","price":279.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/ELK_528bac50-f75a-4bce-ac53-d52c582cef27.jpg?v=1751164370","url":"https:\/\/danabiosci.com\/products\/ept303","provider":"Dana Bioscience","version":"1.0","type":"link"}
