HUMAN IL-4

The Uses of HUMAN IL-4

Interleukin-4 (IL-4) has been used as a stimulant of M2 state of microglia that is associated with wound healing and debris clearance.

The Uses of HUMAN IL-4

Lymphokine with profound effects on the growth and differentiation of immunologically competent cells, inhibits VEGF-induced and βFGF-induced angiogenesis.

The Uses of HUMAN IL-4

IL-4 (interleukin 4) has been used to polarize the human monocytic leukemia (THP-1) cells to M2-like phenotype.

General Description

IL-4 is a pleiotropic cytokine that regulates diverse T and B cell responses including cell proliferation, survival and gene expression. Produced by mast cells, T cells and bone marrow stromal cells, IL-4 regulates the differentiation of naive CD4+ T cells into helper Th2 cells, characterized by their cytokine-secretion profile that includes secretion of IL-4, IL-5, IL-6, IL-10, and IL-13, which favor a humoral immune response. Another dominant function of IL-4 is the regulation of immunoglobulin class switching to the IgG1 and IgE isotypes. Excessive IL-4 production by Th2 cells has been associated with elevated IgE production and allergy. Recombinant human IL-4 is a 14.9 kDa globular protein containing 129 amino acid residues.
