Natural killer cells: in health and disease once the target is recognized by nk cells nk cells recognize tumor cells as targets. But there is growing interest in cells considered part of the innate immune system, particularly natural killer (nk) cells nk cells have the potential to destroy virus-infected cells by several mechanisms, including the identification of generic signs of cellular distress or infection, or via antibody-mediated recruitment to a target cell (known as.
They are known as “natural killer cells” or nk cells nk cells bind themselves to the diseased or infected target cells and release a potent cytotoxic chemical called tumour necrosis factor (tnf) that kills these cells nk cells form a normal part of our blood and play an important role in our bodies’ defence mechanism. Natural killer cells by: natural killer (nk) cells target and kill nk cells are like other types of t-cells which recognise and kill virus-infected cells.
