Overview

Interleukin 2 (IL-2) is a monomeric cytokine that was originally identified as a T cell growth factor (Gaffen & Liu). It binds to a heterotrimeric receptor consisting of CD25, CD122, and CD132. Upon binding, it activates JAK3-, STAT5-, and AKT-dependent signaling pathways, which results in cellular proliferation and survival (Ma et al.). The majority of IL-2 is secreted by activated CD4+ and CD8+ T cells, although B cells and dendritic cells were found to produce IL-2 in small amounts. IL-2 downregulates immune responses to prevent autoimmunity during thymic development, influences the development of CD4+CD25+ regulatory T cells, and affects development of follicular helper T cells. IL-2 also controls inflammation by inhibiting Th17 differentiation (Banchereau et al.). Targeted deletions of the IL-2 gene in mice resulted in development of autoimmune hemolytic anemia, followed by ulcerative colitis. Similar effects were observed in mice that were deficient in IL-2 receptor α (Gaffen & Liu).

Data and Publications

Data

(A) The biological activity of Mouse Recombinant IL-2 was tested by its ability to promote the proliferation of CTLL-2 cells. Cell proliferation was measured after 3 days of culture using a fluorometric assay method. The EC50 is defined as the effective concentration of the protein at which cell proliferation is at 50% of maximum. The EC50 in the example above is 1.12 ng/mL. (B) 1 μg of Mouse Recombinant IL-2 was resolved with SDS-PAGE under reducing (+) and non-reducing (-) conditions and visualized by Coomassie Blue staining. Mouse Recombinant IL-2 has a predicted molecular mass of 17.4 kDa.
