An immune response involves Lymphocytes (B-cells and T-cells) and antigen presenting cells (macrophages, B-cells, and dendritic cells). Clonal selection is the proliferation of B-cell and T-cell clones against a specific antigen. B-cell responses are called Humoral immune responses. T-cell responses are called cell-mediated immune responses. The pathway used to present antigens to the immune system depends on weather the antigen is an exogenous antigen or endogenous antigen.
