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.

Emirodatamab
0 ImagesSynonyms: AMG-427Emirodatamab (AMG-427) is a bispecific T-cell engager (BiTE). Emirodatamab simultaneously binds FLT3 on the surface of acute myeloid leukemia (AML) cells and CD3 on the surface of T cells, thereby precisely recruiting immune effector cells to tumor sites. Emirodatamab potently induces T cell activation, secretion of proinflammatory cytokines (such as IFNγ, TNFα), and specific cytotoxicity, effectively lysing FLT3-positive tumor cells and inhibiting their growth. Emirodatamab not only significantly prolongs survival in mouse xenograft models and eliminates diseased cells in primates, but also exhibits a synergistic enhancement effect when combined with PD-1 blockade therapy. Emirodatamab is used in studies of acute myeloid leukemia, especially relapsed or refractory cases.

Lck-IN-5
0 ImagesLck-IN-5 (example C10) is a potent and selective lymphocyte-specific protein tyrosine kinase (LCK) inhibitor. Lck-IN-5 selectively disrupts the interaction between the SH3 domain of LCK and the RK motif of CD3ε, thereby impairing LCK recruitment to the TCR. Lck-IN-5 modulates the activity of CD3ε-containing CAR and TRuC T cells, attenuating cytokine production and promoting a central-memory-like phenotype associated with enhanced persistence. Lck-IN-5 can be used for autoimmune diseases and graft-versus-host disease research.
