Detailed explanation-1: -Cytotoxic T cells recognize antigen bound to MHC protein type 1.
Detailed explanation-2: -Cytotoxic T cells (TC) express CD8, which recognizes class I MHC proteins, whereas helper T cells (TH) express CD4, which recognizes class II MHC proteins.
Detailed explanation-3: -1: MHC I are found on all nucleated body cells, and MHC II are found on macrophages, dendritic cells, and B cells (along with MHC I).
Detailed explanation-4: -The surface of a cytotoxic T-cell has something called a CD8 receptor. The CD8 receptor interacts with cells called major histocompatibility complex (MHC) Class I molecules to recognize when healthy cells are infected. When the CD8 receptor recognizes an infected cell, it activates the cytotoxic T-cells.
