Humoral immunity is the element of immunity that is present in the serum, and consists of immunoglobulins (antibodies). Antibodies are produced by B lymphocytes, and they exist in a soluble form in blood serum. Their function is to bind and inhibit infectious agents or secreted toxins. Antibody binding can neutralize the ability of a pathogen to infect, or prevent toxins from killing cells. Binding of antibody to the surface of a pathogen can also activate the complement system, which can form pores in the outer membrane and kill the organism.
Cellular immunity consists of T lymphocytes. Rather than recognizing a protein from an infectious agent directly, these cells only recognize proteins that have been partly degraded by cells of the host, peptides from which are presented on MHC molecules ...
