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 adaptive immune response can be either humoral or cell-mediated. The humoral response is mediated by B lymphocytes, which release antibodies specific to the infectious agent. The cell-mediated response involves the binding of cytotoxic T lymphocytes to foreign or infected cells, followed by the lysis of these cells.he components of the innate immune system provide a first line of defense against infection. Physical barriers to infection include skin, which prevents pathogen penetration, and bodily fluids like mucus, which collect and clear pathogens.
