商名	HumanKine®
描述	HumanKine® IL-4, Human Recombinant Xeno-Free
Alternate Names	IL4 Interleukin-4
背景信息	Interleukin-4 (IL-4) is a cytokine that stimulates activated B-cell and T-cell proliferation and induces differentiation of naive helper T cells (Th0 cells) to Th2 cells. These Th2 cells, in turn, also produce IL-4. IL-4 also acts as a key regulator in humoral and adaptive immunity and induces B-cell class switching to IgE, as well as up-regulating MHC class II production. Mutations in the IL-4 gene may lead to a susceptibility to ischemic stroke or cerebral infarction. Overproduction of IL-4 is associated with allergies.
