CD3

Cluster of differentiation 3

CD3 (cluster of differentiation 3) is a protein complex and T cell co-receptor that is involved in activating both the cytotoxic T cell (CD8+ naive T cells) and T helper cells (CD4+ naive T cells). It is composed of four distinct chains. In mammals, the complex contains a CD3γ chain, a CD3δ chain, and two CD3ε chains. These chains associate with the T-cell receptor (TCR) and the CD3-zeta (ζ-chain) to generate an activation signal in T lymphocytes. The TCR, CD3-zeta, and the other CD3 molecules together constitute the TCR complex.

    Mipletamig
    		Inhibitor 99%
    Mipletamig (APVO-436) is a bispecific CD123 x CD3 monoclonal antibody. Mipletamig simultaneously binds to both CD3-expressing T cells and CD123-expressing cancer cells, thereby crosslinking CD123-expressing tumor cells and cytotoxic T lymphocytes (CTLs). This results in the activation and proliferation of T-cells and causes CTL-mediated cell lysis of CD123-expressing tumor cells. Mipletamig can be used for the study of acute myeloid leukemia (AML).
