Cell Mediated And Humoral Immunity

In this animation it is shown how white blood cells called macrophages lead the body's cell mediated response by coming into contact and digesting born invaders and also how macrophages build antigens on its surface. It describes what happens when another white blood cell called a helper T - cell encounters the macrophage. If the helper T- cell has a matching receptor to the macrophage then it will bind to the macrophage's surface. It also go into how the helper T- cells multiply and secrete chemicals to help with the response against the invaders. This animation also explains a little about humoral immunity as well and how in humoral immunity B - cells produce the antibodies. It goes into how the B - cells reproduce and what kind of cells they produce into. In general this animation decribes how these two types of immunity respond and what is involved in both responses. This relates to biol 440 because we have discussed both types of immunity as well as T- cells and B- cells.
