CC   -!- FUNCTION: Cytokine secreted primarily by mast cells, T-cells,
CC       eosinophils, and basophils that plays a role in regulating antibody
CC       production, hematopoiesis and inflammation, and the development of
CC       effector T-cell responses (PubMed:3016727, PubMed:1993171). Induces the
CC       expression of class II MHC molecules on resting B-cells. Enhances both
CC       secretion and cell surface expression of IgE and IgG1 (PubMed:1993171).
CC       Regulates also the expression of the low affinity Fc receptor for IgE
CC       (CD23) on both lymphocytes and monocytes (PubMed:2521231). Positively
CC       regulates IL31RA expression in macrophages. Stimulates autophagy in
CC       dendritic cells by interfering with mTORC1 signaling and through the
CC       induction of RUFY4. In addition, plays a critical role in higher
CC       functions of the normal brain, such as memory and learning (By
CC       similarity). Upon binding to IL4, IL4R receptor dimerizes either with
CC       the common IL2R gamma chain/IL2RG to produce the type 1 signaling
CC       complex, located mainly on hematopoietic cells, or with the IL13RA1 to
CC       produce the type 2 complex, which is expressed also on nonhematopoietic
CC       cells (PubMed:10219247, PubMed:11526337, PubMed:18243101). Engagement
CC       of both types of receptors initiates JAK3 and to a lower extend JAK1
CC       phosphorylation leading to activation of the signal transducer and
CC       activator of transcription 6/STAT6 (PubMed:7721895).

CC   -!- DISEASE: Ischemic stroke (ISCHSTR) [MIM:601367]: A stroke is an acute
CC       neurologic event leading to death of neural tissue of the brain and
CC       resulting in loss of motor, sensory and/or cognitive function. Ischemic
CC       strokes, resulting from vascular occlusion, is considered to be a
CC       highly complex disease consisting of a group of heterogeneous disorders
CC       with multiple genetic and environmental risk factors.
