â¢ Humoral immunity is mediated by B-cells while cell-mediated immunity is mediated by T-cells. â¢ In the humoral immunity, the B-cells secrete antibodies whereas in the cell-mediated immunity, the T-cells do not secrete receptors. T-cell receptors are bound to the T-cells and the cells themselves bind with antigens. The antibodies are used in the humoral immunity whereas the receptors are used in the cell-mediated immunity to defend against pathogens. â¢ Unlike in the cell-mediated immunity, the antigens are destroyed by B-cell antibodies outside the B-cells in the humoral immunity.

Every effective immune response involves T-cell activation; however, T-cells are especially important in cell-mediated immunity, which is the defense against tumor cells and pathogenic organisms inside body cells. They are also involved in rejection reactions.umoral immunity is mediated by secreted antibodies, produced in the cells of the B lymphocyte lineage (B-cell). Secreted antibodies bind to antigens on the surfaces of invading microbes, which flags them for destruction. Humoral immunity refers to antibody production, and all the accessory processes that accompany it.
