Question

Quizplus · Accepted Answer

The deactivation of NK cells due to binding of NK receptors to MHC I proteins is called licensing. This occurs when the NK cell recognizes normal healthy cells, which express MHC I molecules on their surface. The recognition of MHC I by inhibitory NK receptors provides a signal to the NK cell that prevents it from killing the healthy cell. This is important to prevent NK cells from attacking and killing healthy cells in the body.
