cd3 complex การใช้

• The protein encoded by this gene is the CD3-epsilon polypeptide, which together with CD3-CD3 complex.
• Past this period CD3 blocks the TCR-antigen binding and causes conformational change or the removal of the entire TCR3 / CD3 complex from the T-cell surface.
• When a T h cell encounters and recognises the antigen on an APC, the CD3 complex binds strongly to the peptide-MHC complex present on the surface of professional APCs.
• Although it is not thought to directly target components of the TCR / CD3 complex, Alemtuzumab, or Campath-1H, has been utilized because of its strong ability to deplete T cells, in many cases for up to 3 years.
• Phosphorylation of TCR / CD3 complexes that entered the close-contact zone but did not bind their peptide-MHC ligand is too short-lived to induce signaling because they rapidly diffuse out of the segregation zone back to the vicinity of inhibitory tyrosine phosphatases.
