Helper T Cell Diagram. Other lymphokines prevent migration of macrophages away from the site of infection. Certain helper T cells secrete lymphokines or interleukins substances that activate macrophages and other lymphocytes. When a B-cell is activated by the interaction with a helper T-cell it begins to produce and disperse antibodies. Thus the helper T cell activates those B cells with receptors that specifically recognize the antigen that initially activated the T cell although the T and B cells usually recognize distinct antigenic determinants on the antigen see Figure 24-70.

The bumps on the T-cell are T-cell receptors used to fight infections. Subsets of Th cells are defined by the class of cytokine that they secrete upon activation. In secondary antibody responses memory B cells themselves can act as antigen-presenting cells and activate helper T cells as well as being the subsequent targets of the effector helper T cells. Another type of white blood cell that is involved in the cell mediated response is a helper T-cell.

The Helper T-cells coordinate the attack. TH2 cells produce cytokines such as IL-4 IL-5 and IL-13 that recruit and activate a variety of cell types such as eosinophils and mast cells as well as promote other immune responses at mucosal surfaces against extracellular pathogens particularly helminthes. According to Model 1 are all helper T-cells the same.

In talking about the adaptive immune system weve already seen that theres a couple of actors let me write this down adaptive or specific immune system adaptive immune system you have your humoral response humoral so this is responding to things that are floating around in the fluids of the body and not necessarily things that have infiltrated your body cells and then you have your cell mediated cell.
