As a first line of defense, they destroy invading pathogens, foreign bodies, and infected cells in early stages, thereby preventing them from spreading. NK cells can circulate within the bloodstream (circulatory) or reside in tissue and organs. Having too few NK cells can lead to immune system dysfunction and increase susceptibility to disease. https://medicalxpress.com/news/2025-12-anxiety-insomnia-natural-killer-cell.html Wed, 10 Dec 2025 00:00:01 EST news684496938 It starts with a sneeze.
