General description

Interleukin-4 (IL-4) is a pleiotropic cytokine that regulates diverse T and B cell responses including differentiation of naive T cells into the TH2 phenotype, promoting B cell proliferation, antibody isotype switching, and expression of other TH2 cytokines including IL-5 and IL-9.1,2 IL-4 plays a critical role in the development of allergic inflammation and asthma.3

IL-4 binds to two distinct receptors; the type I receptor, a heterodimer consisting of the IL-4Rα chain and the common gamma chain, γc, and the type II receptor, a heterodimer of IL-4Rα and IL-13Rα1.4

Naturally occurring IL-4 has a molecular mass of 12-20 kDa. Recombinant human IL-4 is a 14.9 kDa protein containing 129 amino acid residues. Human and mouse IL-4 share a 50% amino acid sequence homology, but their biological actions are species-specific.5

Application

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

Physical form

Lyophilized from a sterile filtered solution.

Analysis Note

The biological activity is measured by the dose-dependent stimulation of the proliferation of human TF-1 cells.

Macrophage polarization and infiltration to the tumor microenvironment (TME) is a critical determining factor for tumor progression. Macrophages are polarized into two states-M1 (pro-inflammatory, anti-tumorigenic and stimulated by LPS or IFN-γ) and M2 (anti-inflammatory pro-tumorigenic and stimulated by IL-4) phenotypes.
