The binding between TCR and antigen is of relatively low affinity and is degenerate: that is, many TCRs recognize the same antigen and many antigens are recognized by the same TCR.The TCR is composed of two different protein chains (that is, it is a heterodimer). In man 95% of T cells the TCR consists of an alpha (α) and beta (β) chain, whereas in 5% of T cells the TCR consists of gamma and delta (γ/δ) chains. This ratio changes during ontogeny and in diseased states as well as in different species.When the TCR engages with antigenic peptide and MHC (peptide/MHC), the T lymphocyte is activated through signal transduction, that is, a series of biochemical events mediated by associated enzymes, co-receptors, specialized adaptor molecules, and activated or released transcription factors."@en }
