Background

In immunology, CD3 (Differentiated Cluster 3) of T cells is a protein complex. CD3 has five peptide chains, namely, the γ, δ, ε, ζ, and η chains, all of which are transmembrane proteins. The transmembrane region of the CD3 molecule is connected to the transmembrane region of the two peptide chains of TCR through a salt bridge to form the TCR-CD3 complex, which jointly participates in the recognition of antigen. The activation signal generated by TCR antigen recognition is generated and transduced by CD3. Mononuclear cells isolated from peripheral blood, bone marrow, or umbilical cord blood can obtain large numbers of proliferating T lymphocytes in the presence of CD3 monoclonal antibodies and various cytokines.
