Explanation:
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: -Negative selection is the process that eliminates developing lymphocytes whose antigen receptors bind strongly to self antigens present in the lymphoid organs. Both developing B cells and T cells are subject to negative selection during a short period after antigen receptors are expressed.
