Detailed explanation-1: -Armed effector cytotoxic CD8 T cells are essential in host defense against pathogens that live in the cytosol, the commonest of which are viruses. These cytotoxic T cells can kill any cell harboring such pathogens by recognizing foreign peptides that are transported to the cell surface bound to MHC class I molecules.
Detailed explanation-2: -Cytotoxic T lymphocytes (CTLs) represent one of several types of cells of the immune system that have the capacity to directly kill other cells. They play a major role in host defense against viral infection, as well as infection by other intracellular pathogens that replicate in the cytoplasm of the host cell.
Detailed explanation-3: -Cytotoxic T cells (CTLs) are a key component of the adaptive immune system and are key for destruction of viral infected cells (Nutt and Huntington, 2019). These T cells recognise antigen, via their T cell receptor, presented in MHC class I molecules.
Detailed explanation-4: -T cells regulate the activities cells participating in immune responses. They provide help for antibody production by B cells, and they are also the effectors of antigen-specific cell-mediated immunity (CMI).
