T- and B-lymphocyte,illustration
T-lymphocyte (red) and B-lymphocyte (blue),computer artwork. These white blood cells are part of the immune system. B cells mature in bone marrow and are responsible for humoral immunity; they operate by recognising a specific site (antigen) on the surface of a pathogen or foreign object,which they bind to before producing antibodies to destroy that antigen. T cells mature in the thymus and are involved in cell-mediated immunity,which does not rely on antibodies to fight antigens,but rather the activation of other immune cells. Interaction between B and T cells can increase B cell antibody production
