Antibodies contribute to immunity in three main ways: they can prevent pathogens from entering or damaging cells by binding to them; they can stimulate removal of a pathogen by macrophages and other cells by coating the pathogen; and they can trigger direct pathogen destruction by stimulating other immune responses such as the complement pathway.
A monoclonal antibody is directed against a specific protein in the cancer cells, and it does not affect the cells that do not have that protein. When a monoclonal antibody attaches to a cancer cell, they may accomplish the following goals: Allow the immune system to destroy the cancer cell.nterferons. Interferons help the immune system fight cancer and may slow the growth of cancer cells. An interferon made in a laboratory, called interferon alpha (Roferon-A [2a], Intron A [2b], Alferon [2a]), is the most common type of interferon used in cancer treatment.
