PATHOLOGY

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: -Follicular helper T (TFH) cells are a specialized subset of CD4+ T cells that provide help to B cells through both cell-cell interactions and release of cytokines, leading to the production of antibodies by B cells [1].

Detailed explanation-3: -However, the T-cell receptor differs from the B-cell receptor in an important way: it does not recognize and bind antigen directly, but instead recognizes short peptide fragments of pathogen protein antigens, which are bound to MHC molecules on the surfaces of other cells.

Detailed explanation-4: -Both B and T cells originate in the bone marrow. These cells are involved in adaptive immunity. They are a type of lymphocytes. The cells are nucleated and motile. Both protect the body’s immune system and help fighting infections. More items •25-Jun-2020
