It is a protein that in humans is encoded by the IL13 gene. Interleukin-13 is an immunoregulatory cytokine produced primarily by activated Th2 cells.It is involved in several stages of B-cell maturation and differentiation. It up-regulates CD23 and MHC class II expression, and promotes IgE isotype switching of B cells. This cytokine down-regulates macrophage activity, thereby inhibits the production of pro-inflammatory cytokines and chemokines. This cytokine is found to be critical to the pathogenesis of allergen-induced asthma but operates through mechanisms independent of IgE and eosinophils. \u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48647910752356,"sku":"EPT242","price":379.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_93ec334d-bd73-4d07-b4e0-81cf8d65f271.jpg?v=1782704680","url":"https:\/\/www.genebiosystems.com\/en-de\/products\/recombinant-human-il-13-c-fc","provider":"GeneBio ","version":"1.0","type":"link"}
