The interleukin 4 (IL4, IL-4) is a cytokine that induces differentiation of naive helper T cells (T h 0 cells) to T h 2 cells. Upon activation by IL-4, T h 2 cells subsequently produce additional IL-4 in a positive feedback loop.

Interleukin-4 (IL-4) is a four-α-helical bundle type I cytokine with broad pleiotropic actions on multiple lineages. Major actions of IL-4 were initially discovered for B and T cells, but this cytokine acts on more than a dozen different target ...

2022年8月22日 · Interleukin-4 (IL-4) CD4+T cells (Th2) synthesize IL-4, and it acts on both B and T cells. It is a B-cell growth factor and causes IgE and IgG1 isotype selection. It causes Th2 differentiation and proliferation, and it inhibits IFN gamma-mediated activation on macrophages. It promotes mast cell proliferation in vivo. Interleukin-5 (IL-5)

Lipopolysaccharide-induced interleukin (IL)-4 receptor-alpha expression and corresponding sensitivity to the M2 promoting effects of IL-4 are impaired in microglia of aged mice. Brain, behavior, and immunity. 2012;26:766–777. doi: 10.1016/j.bbi.2011.10.003.

Interleukin-4 is a cytokine that is produced by various cells and plays a role in exerting anti-inflammatory effects during infections like tuberculosis. AI generated definition based on: Tuberculosis , 2009

Keywords: alternative splicing, interelukin-4 receptor, interleukin-4 signaling, alternative macrophage activation. Abstract. Studies of IL-4 have revealed a wealth of information on the diverse roles of this cytokine in homeostatic regulation and disease pathogenesis.

2018年6月6日 · Interleukin (IL)-4 and IL-13 are related cytokines that regulate many aspects of allergic inflammation. They play important roles in regulating the responses of lymphocytes, myeloid cells, and non-hematopoietic cells.

2005年7月19日 · Interleukin-4 (IL-4) is a cytokine produced by T(H)2 type helper T cells and by mast cells, basophils, and eosinophils. This cytokine can elicit many responses, some of which are associated with allergy and asthma.

Interleukin 4 (IL-4) is a pleiotropic type I cytokine that controls both growth and differentiation among haemopoietic and non-haemopoietic cells. Its receptor is a heterodimer. One chain, the IL-4R alpha chain, binds IL-4 with high affinity and determines the …

2021年9月7日 · Interleukin-4 (IL-4) is a four-α-helical bundle type I cytokine with broad pleiotropic actions on multiple lineages. Major actions of IL-4 were initially discovered for B and T cells, but this cytokine acts on more than a dozen different target cells spanning the innate and adaptive immune systems a …
