WebJan 17, 2024 · It is a mechanism to stop viral infections and cancer development and is a result of cellular stress. Natural killer (NK) cells are cytotoxic lymphocytes critical to the innate immune system. The role of NK cells is similar to that of cytotoxic T cells in the adaptive immune response. WebCytotoxicity is the quality of being toxic to cells. Examples of toxic agents are an immune cell or some types of venom, e.g. from the puff adder ( Bitis arietans) or brown recluse spider ( Loxosceles reclusa ). Cell physiology [ edit] Treating cells with the cytotoxic compound can result in a variety of cell fates.
