ASPECTS OF RECEPTOR BINDING AND SIGNALLING OF INTERLEUKIN-4 INVESTIGATED BY SITE-DIRECTED MUTAGENESIS AND NMR SPECTROSCOPY
Template:ABSTRACT PUBMED 8151703
Disease
[IL4_HUMAN] 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.[1]
Function
[IL4_HUMAN] 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.
