| 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. |
For laboratory
research and ex vivo cell isolation
and culture applications. Direct human use, including taking orally and
injection and clinical use are forbidden.
