Question

Quizplus · Accepted Answer

Licensing of NK cells is a process that ensures NK cells can distinguish between healthy host cells and abnormal cells (such as infected or cancerous cells). This is achieved by interactions between inhibitory receptors on NK cells and MHC class I molecules on healthy cells. When an NK cell encounters a cell lacking these molecules (indicating potential abnormality), it is more likely to activate and attack. This process effectively "tests" NK cells to prevent them from targeting healthy host cells, aligning with option E.
