Humoral immunity is called active when the organism generates its own antibodies, and passive when antibodies are transferred between individuals or species. Similarly, cell mediated immunity is active when the organismsâ own T-cells are stimulated, and passive when T cells come from another organism.
Stimulate B cells that have already become bound to antigen. T H cells interact directly with B cells that have antigen fragments on their surfaces bound to MHC II receptors T H cells stimulate B cells to divide more rapidly and begin antibody formation Cytokines released by T H amplify nonspecific defenses.
