Transforming growth factor beta 2 ( TGFB2) is also known as TGF-β2, G-TSF, TGFB. is a polypeptide member of the transforming growth factor beta superfamily of cytokines. It is a secreted protein that performs many cellular functions, including the control of cell growth, cell proliferation, cell differentiation and apoptosis. The TGFB2 protein helps control the growth and division (proliferation) of cells, the process by which cells mature to carry out specific functions (differentiation), cell movement (motility), and the self-destruction of cells (apoptosis). The TGFB2 protein can inhibit the T cell growth by IL-2-dependent. and can inhibit immune surveillance during tumor development, the protein promoting tumor growth with an autocrine manner. TGF-β2 can affect the viability of killer cells and reduce the expression of IL-2, IL-6, IL-10, IFN-γ and other cytokines.TGFB2 plays an important role in controlling the immune system, and shows different activities on different types of cell, or cells at different developmental stages.
