NK (Natural Killer) Cell

If you can imagine "Death" as an immune cell, it would probably be NK (Natural Killer) cells. Belonging to the T lymphocyte family, these cells are so-called because they are killers adept at eliminating cancerous or virus-infected cells, which they recognize thanks to specific flags on their surfaces.

NEWS FLASH: NK cells will give the "traitor" cells a kiss of death, which will trigger the cycle of their death. This kiss is manifested by direct contact between the two cells.

Naturally, all that's left to do is get to it!
