It is a cytokine with immunoregulatory activity. Cytokines are proteinaceous signaling compounds that are major mediators of the immune response. They control many different cellular functions including proliferation, differentiation and cell survival\/apoptosis but are also involved in several pathophysiological processes including viral infections and autoimmune diseases. Cytokines are synthesized under various stimuli by a variety of cells of both the innate (monocytes, macrophages, dendritic cells) and adaptive (T- and B-cells) immune systems. IL21 is expressed in activated CD4-positive T-cells but not in CD8-positive T-cells, B-cells, or monocytes. It may promote the transition between innate and adaptive immunity. IL-21 has been tried as therapy for alleviating allergic responses. It can significantly decrease pro-inflammatory cytokines produced by T cells in addition to decreasing IgE levels in a mouse model for rhinitis (nasal passage inflammation)\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Elabscience Biotechnology","offers":[{"title":"100μg","offer_id":40726059581498,"sku":"PKSH031514-100","price":1402.95,"currency_code":"USD","in_stock":true},{"title":"20μg","offer_id":40726060924986,"sku":"PKSH031514-20","price":437.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7785\/files\/imy94K_fa33df9b-23d0-4baa-abf6-9fd9ee823b85.jpg?v=1732621706","url":"https:\/\/www.msesupplies.com\/en-gb\/products\/recombinant-human-interleukin-21-il-21-protein-active","provider":"MSE Supplies","version":"1.0","type":"link"}
