They belong to the rapidly growing innate lymphoid cell (ILC) family and account for 5–20 percent of all circulating lymphocytes in humans. NK cells play a similar function to cytotoxic T cells.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eNK cells Mechanism\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eNK cells react quickly to virus-infected cells, starting to function three days after infection, and they also respond to tumour formation. Immune cells sense the major histocompatibility complex (MHC) on infected cell surfaces, which triggers the release of cytokines, which causes the infected cell to die through lysis or apoptosis.\u003cbr data-mce-fragment=\"1\"\u003eThey were given the name \"natural killers\" because they destroy cells that lack MHC class 1 \"self\" markers without the need for activation. This role is critical since dangerous cells lacking MHC I markers cannot be identified and killed by other immune cells, such as T lymphocyte cells.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eKiller Cell Function\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe function of the NK cells includes; cytolytic granule-mediated cell apoptosis, antibody-dependent cell-mediated cytotoxicity (ADCC), Cytokine-induced NK, and Cytotoxic T lymphocyte (CTL) activation, tumour cell surveillance and clearance of senescent cells.\u003cbr data-mce-fragment=\"1\"\u003eThe ability of T and B cells to produce memory cells after a primary infection, as well as the subsequent rapid immune activation and response to subsequent infections by the same antigen, is critical to the adaptive immune response. For a long time, NK cells were thought to be part of the innate immune system. However, new evidence indicates that NK cells may exhibit many characteristics that are normally associated with adaptive immune cells, e.g., T cell responses.\u003c\/p\u003e","products":[{"product_id":"kir2dl1-human","title":"KIR2DL1 Human","description":"\u003cp\u003eKiller Cell Immunoglobulin-Like Receptor, 2 Domains Long Cytoplasmic Tail 1
