True or false Natural killer cells kill cancer cells?
True, NK cells are there to protect the body from any type of abnormal growth in all tissues including cancer cells.
If cancer cells are foreign and harmful to our body how come our immune system doesn't fight it?
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.
Cancer cells and virus-infected body cells can be killed before activation of adaptive immunity by?
Cancer cells and virus infected body cells can be killed before activation of adaptive immunity by natural killer cells. These may be noted as NK cells in literature.
