[[http://www.uniprot.org/uniprot/IL4_HUMAN IL4_HUMAN]] Genetic variations in IL4 may be a cause of susceptibility to ischemic stroke (ISCHSTR) [MIM:[http://omim.org/entry/601367 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.<ref>PMID:14681304</ref>

[[http://www.uniprot.org/uniprot/IL4_HUMAN 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. [[http://www.uniprot.org/uniprot/IL4RA_HUMAN IL4RA_HUMAN]] Receptor for both interleukin 4 and interleukin 13. Couples to the JAK1/2/3-STAT6 pathway. The IL4 response is involved in promoting Th2 differentiation. The IL4/IL13 responses are involved in regulating IgE production and, chemokine and mucus production at sites of allergic inflammation. In certain cell types, can signal through activation of insulin receptor substrates, IRS1/IRS2.<ref>PMID:8124718</ref> Soluble IL4R (sIL4R) inhibits IL4-mediated cell proliferation and IL5 up-regulation by T-cells.<ref>PMID:8124718</ref>
