      Background InformationInterleukin-4 (IL-4) is a cytokine that stimulates activated B-cell and T-cell proliferation and induces differentiation of naive helper T cells (Th0 cells) to Th2 cells. These Th2 cells, in turn, also produce IL-4. IL-4 also acts as a key regulator in humoral and adaptive immunity and induces B-cell class switching to IgE, as well as up-regulating MHC class II production. Mutations in the IL-4 gene may lead to a susceptibility to ischemic stroke or cerebral infarction. Overproduction of IL-4 is associated with allergies.

      Entrez Gene Number
      Entrez Gene SummaryThe protein encoded by this gene is a pleiotropic cytokine produced by activated T cells. This cytokine is a ligand for interleukin 4 receptor. The interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of this cytokine. This gene, IL3, IL5, IL13, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL13. This gene, IL13 and IL5 are found to be regulated coordinately by several long-range regulatory elements in an over 120 kilobase range on the chromosome. Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported. [provided by RefSeq].

      UniProt Number
      UniProt SummaryFUNCTION: 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.

      DISEASE: Genetic variations in IL4 may be a cause of susceptibility to ischemic stroke [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.

      SIMILARITY: Belongs to the IL-4/IL-13 family.
      Molecular WeightUniProtKB/Swiss-Prot entry P05112 (IL4_HUMAN) describes 2 isoforms produced by alternative splicing: isoform 1 at 18 kDa and isoform 2 at 16 kDa. Recombinant Human Interleukin-4 (Millipore Cat # IL004) is observed at 15 kDa.
