技術背景

Target Background ：CD28 (Cluster of Differentiation 28) is one of the proteins expressed on T cells that provide co-stimulatory signals required for T cell activation and survival. It plays an important role in cell proliferation and cytokine production and promotion of T-cell survival. It also enhances the production of IL-4 and IL-10 in T cells in conjunction with TCR/CD3 ligation and CD40L co-stimulation. 

Synonyms： CD28; TP44; T-cell-specific surface glycoprotein CD28; Cluster of differentiation 28
