Abnormal Natural Killer Cell Physiology C4023012

Published: July 22, 2026Updated: August 20, 2026

Abnormal natural killer cell physiology refers to dysfunction in how these immune cells work, rather than just their appearance. This can weaken the body's ability to fight viruses and abnormal cells. Treatment involves addressing the underlying condition affecting NK cell function.
