Humoral and Cell Mediated Immune Responses against Viral and Bacterial Infections

The humoral immune responses are based on antibodies; it can be applied on humans who are non-immune, by dealing with serum antibodies from an immune person. Antibodies act as the effectors of humoral reaction. (Pier, 2004, pp. 15)

In contrast, cell-mediated immunity is based on T-cells, which are a type of lymphocyte. T-cells are of the following two types: T-helper (TH) and T-cytotoxic (Tc) cells. When a TH-cell interacts with an antigen-MHC II molecule complex present on an APC, it ...
