Detailed explanation-1: -There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins. The T cells destroy the body’s own cells that have themselves been taken over by viruses or become cancerous.
Detailed explanation-2: -There are several types of T cells; the most common and well-known are the CD4+ T cells (helper T cells) and CD8+ T Cells (cytotoxic T cells, or killer T cells). T cells cannot recognize soluble, free antigens. T cells can only recognize protein-based, receptor-bound antigens.
Detailed explanation-3: -B-cells can connect to antigens right on the surface of the invading virus or bacteria. T-cells can only connect to virus antigens on the outside of infected cells. -cells form humoral or antibody-mediated immune system (AMI). T-cells form cell-mediated immune system (CMI).
Detailed explanation-4: -T cell and B cell lymphocytes work together to recognize foreign substances called antigens. As the primary agents responsible for adaptive immunity, T cells and B cells are sometimes called the “special ops” of the immune system.
