This lesson gives an idea about the immune responses. There are mainly two types of immune responses, the first one is humoral mediated and the second one is cell mediated immune response. In humoral mediated immune response it is the B lymphocyte that plays an important role. When a B lymphocyte which has an antibody receptor on its surface comes across an antigen these gives rise to a clone of cells.A few of these becomes effector cells and the others memory cells. Where as in cell mediated immune response it is T lymphocyte that plays an important role. They bind to antigens like virus, bacteria,fungus and parasites and also gives rise to a clone of cells. They also secrete lymphokines which help the cells to kill the target more efficiently.
