Natural Killer (NK) cells play a crucial role in the immune system’s defense against cancer.
They induce cancer cell death primarily through two mechanisms: apoptosis and necrosis.
Apoptosis is a programmed, non-infiammatory form of cell death, while necrosis is a more abrupt and inflammatory process.
In many cases, NK cells can trigger a combination of both, leading to mixed forms of cell death.
This dual capability allows NK cells to effectively target and destroy a wide range of tumor cells.
Their ability to act without prior sensitization makes them vital for early cancer surveillance and immunotherapeutic strategies.
