IL-4 also can rescue B-cells from apoptosis, enhancing their survival, and is responsible for immunoglobulin isotype switching to IgG1 and IgE. The effect of IL-4 signaling is mediated through the IL-4 receptor alpha chain (IL-4Rα). Upon binding to its ligand, IL-4Rα dimerizes either with the common gamma chain (γc) to produce the type-1 signaling complex located mainly on hematopoietic cells, or with the IL-13 receptor alpha 1 (IL-13Rα1) to produce the type-2 complex, which is expressed also on non-hematopoietic cells. The type-1 signaling complex is critical for Th2-skewing of T cells and the development of alternatively activated macrophages (AAMΦs), while the type-2 complex plays a role in non-hematopoietic responses to IL-4 and IL-13.\u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e","brand":"Starter","offers":[{"title":"1x96T","offer_id":42955075256395,"sku":"S0Q3047-1x96T","price":335.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8375\/1499\/files\/AntBioImage_3029016f-0e13-4dba-8e57-970ff2204497.png?v=1785319261","url":"https:\/\/www.antbioinc.com\/products\/human-il-4-single-plex-kit-flow-cytometry-bead-assay-s0q3047","provider":"AntBio","version":"1.0","type":"link"}
