What are B- and T-Cells?
B-Lymphocytes (B-Cells) and T-Lymphocytes (T-Cells) are sub populations of white blood cells and are the soldiers used by the immune system. B-cells are the antibody producers used in Humoral Immune, and T-cells are the shock troops used in Cell Mediated Immunity. They are all borne in the bone marrow, but they mature differently. B-cells mature in the bone marrow, hence the B for bone marrow. T-Cells are matured by proteins produced by the thymus gland, hence the T for thymus. Both sides of the Immune System must function properly in order for the body to have an optimum Immune Response to invading pathogens. ( fact, B-cells will react quicker, proliferate, expand clonally and produce an antibody response more efficiently in the presence of a T-cell response. So it could be said that T-cells divide B-cells to an extent. T-4 & T-8 lymphocyte cells: Central to beginning the immune response is activation of the T-4 lymphocyte (helper cell) activation takes place when the T-4 cell recogni
