NK cells provide rapid responses to virus -infected cells, acting at around 3 days after infection , and respond to tumor formation. Typically, immune cells detect the major histocompatibility complex MHC presented on infected cell surfaces, triggering cytokine release, causing the death of the infected cell by lysis or apoptosis. NK cells are unique, however, as they have the ability to recognize and kill stressed cells in the absence of antibodies and MHC, allowing for a much faster immune reaction. They were named "natural killers" because of the notion that they do not require activation to kill cells that are missing "self" markers of MHC class 1. In addition to natural killer cells being effectors of innate immunity , both activating and inhibitory NK cell receptors play important functional roles, including self tolerance and the sustaining of NK cell activity. NK cells also play a role in the adaptive immune response : [8] numerous experiments have demonstrated their ability to readily adjust to the immediate environment and formulate antigen-specific immunological memory , fundamental for responding to secondary infections with the same antigen. In early experiments on cell-mediated cytotoxicity against tumor target cells, both in cancer patients and animal models, investigators consistently observed what was termed a "natural" reactivity; that is, a certain population of cells seemed to be able to lyse tumor cells without having been previously sensitized to them. The first published study to assert that untreated lymphoid cells were able to confer a natural immunity to tumors was performed by Dr. Henry Smith at the University of Leeds School of Medicine in , [10] leading to the conclusion that the "phenomenon appear[ed] to be an expression of defense mechanisms to tumor growth present in normal mice.
