Explanation:
Detailed explanation-1: -While B-cells produce antibodies to fight infection, T-cells protect people from getting infected by destroying cancerous and infected cells.
Detailed explanation-2: -T cells can wipe out infected or cancerous cells. They also direct the immune response by helping B lymphocytes to eliminate invading pathogens. B cells create antibodies.
Detailed explanation-3: -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.
