功能Participates in at least several B-cell activation processes as well as of other cell types. It is a costimulator of DNA-synthesis. It induces the expression of class II MHC molecules on resting B-cells. It enhances both secretion and cell surface expression of IgE and IgG1. It also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes.
疾病相关Genetic variations in IL4 may be a cause of susceptibility to ischemic stroke (ISCHSTR) [MIM:601367]; also known as cerebrovascular accident or cerebral infarction. A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. Ischemic strokes, resulting from vascular occlusion, is considered to be a highly complex disease consisting of a group of heterogeneous disorders with multiple genetic and environmental risk factors.

Immunohistochemical analysis of rat endometrial tissue, staining IL4 with ab9811.
Antigen retrieval was by heat mediation in a citrate buffer (pH 6) followed by blocking with 1% BSA for 30 minutes. Sections were incubated with primary antibody (1/50) overnight at 4°C. An HRP-goat anti-rabbit IgG was used as the secondary antibody (1/200). Staining was detected using DAB.
