IL-4 is produced by mast cells; T cells; and bone marrow stromal cells. IL-4 regulates the differentiation of naive CD4+ T cells into helper Th2 cells; characterized by their cytokine-secretion profile that includes secretion of IL-4; IL-5; IL-6; IL-10; and IL-13; which favor a humoral immune response. Another dominant function of IL-4 is the regulation of immunoglobulin class switching to the IgG1 and IgE isotypes. Excessive IL-4 production by Th2 cells has been associated with elevated IgE production and allergic response.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Elabscience Biotechnology","offers":[{"title":"50μg","offer_id":40754242060346,"sku":"PKSH033456-50","price":352.95,"currency_code":"USD","in_stock":true},{"title":"10μg","offer_id":40754242093114,"sku":"PKSH033456-10","price":139.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7785\/files\/Untitled-1_f3b3b99f-d4f6-49f8-9ce2-bb3eecbcabe0.jpg?v=1736587462","url":"https:\/\/www.msesupplies.com\/en-gb\/products\/recombinant-human-interleukin-4-il-4-protein-active-purity-95","provider":"MSE Supplies","version":"1.0","type":"link"}
