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.

The humoral response, mediated by B cells with the help of T cells, produces highâaffinity and antigenâspecific antibodies. This is in contrast with the CD8 Tâcell response which leads to the generation of large numbers of antigenâspecific cells that are capable of directly killing infected cells.he primary immune response of the body to antigen occurs on the first occasion it is encountered. Depending on the nature of the antigen and the site of entry this response can take up to 14 days to resolve and leads to the generation of memory cells with a high specificity for the inducing antigen.
