IMMUNOLOGY

Detailed explanation-1: -The T cell receptor (TCR) is a T cell surface structure that is comprised of a disulfide-linked heterodimer of highly variable and chains expressed at the cell membrane as a complex with the invariant CD3 chains. Most T cells that bear this type of receptor are termed T cells.

Detailed explanation-2: -T-cell receptors (TCR) are composed of two chains, and , that together bind antigenic peptides presented on the multihistocompatability complex (MHC).

Detailed explanation-3: -Structure of the T-cell receptor T-cell receptors consist of two polypeptide chains. The most common type of receptor is called alpha-beta because it is composed of two different chains, one called alpha and the other beta.
