Answer :
The class of leukocytes known as T cells is important for the secondary immune response.
T cells, also known as T lymphocytes, have a protein complex on their surface called the T-cell receptor (TCR), which is in charge of identifying antigen pieces as peptides attached to MHC molecules.
A transmembrane protein called the B cell receptor (BCR) is located on the surface of a B cell. An immunoglobulin molecule that is membrane-bound and a signaling component makes up a B cell receptor. On the outer surface of these lymphocyte cells, the former normally forms a type 1 transmembrane receptor protein.
The abbreviation "T" stands for the thymus, the organ where their growth comes to a stop.
They are in charge of cellular immunity, which is the process by which cells that are alien to the body (as opposed to cells that T cells have learned to accept throughout development, such as cancer cells or virus-infected cells) are eliminated.
T cell receptor (TCR) and B cell receptor (BCR), the two primary lymphocyte subtypes, are both surface-express antigen-recognition receptors. When their receptors specifically attach to antigens like tumors and viruses, they are triggered to start an immune response.
