Natural Killer cells are lymphocytes (white blood cells specialised in immunity) that are cytotoxic, meaning that they produce toxins that affect other cells.
Perforins are pore-forming proteins released by natural killer (NK) cells to induce apoptosis in target cells. They create holes in the cell membrane, leading to osmotic lysis and cell death. This mechanism helps NK cells eliminate virus-infected or abnormal cells.
The strongest white blood cell in your body is considered to be the natural killer (NK) cell. NK cells are able to directly kill infected or cancerous cells without needing prior activation, making them a vital part of the immune system's first line of defense.
Natural killer (NK) cells are a type of white blood cell that can recognize and kill cancerous cells, as well as virus-infected cells. They work by releasing toxic substances that induce apoptosis (cell death) in the target cells. NK cells are a key part of the body's immune system for eliminating abnormal or diseased cells.
Natural killer (NK) cells have receptors that recognize "self" proteins on healthy cells, preventing them from attacking these cells. These receptors help distinguish healthy cells from abnormal or infected cells. Additionally, healthy cells release molecules that send inhibitory signals to NK cells, further preventing them from attacking self cells.
Perforin is produced by cytotoxic T cells (CD8+ T cells) and natural killer (NK) cells. It is used in these cells to induce cell apoptosis in target cells, such as infected or cancerous cells.
The latest review on NK cells highlights their role in immune response against cancer and infections. It discusses how NK cells recognize and kill abnormal cells, and the potential for using NK cell therapy in treating diseases. The review also emphasizes the importance of understanding NK cell biology for developing new treatments.

Natural killer (NK) cells are activated in the immune response through a process called "priming." This involves the recognition of infected or abnormal cells by NK cell receptors, which then trigger the release of cytotoxic molecules to destroy the target cells. Additionally, cytokines released by other immune cells can also stimulate NK cell activity.
Yes our immune system does fight it. These are the NK cells. NK cells naturally present Inhibitory R and NK R. Target cells do not present MHC but present the ligand for NKR. So although lignad on NK binds to NKR, there is no MHC to interact with inhibitory R. So NK cells do not receive inhibitory signal and attacks the cell (e.g. cancerous cell). But at times there may be cancer cells undetected, which is why our immune system can't 'sense' it.
