[[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.
