What is NK Cells ?
NK cells are type of lymphoid cell essential for innate immune system that provide rapid responses to virus infected cells and tumour formation in the absence of prior activation.
Cancers and viral infections developed evasion to avoid T cell recognition but NK cells are able to kill affected cells by distinguishing them from the normal cells. Hence, increasing the number of NK cells may enhance its function and treat diseases like cancer more effectively.
NK cells will not cause side effects as they do not attach healthy cells and will only target infected cells and mutated cells through identifying the lost of MHC I.
