Function of NK cells

Function of NK cells that are especially important for immunity

Immunity is the system built into our bodies to maintain physical health by rapidly detecting, blocking, and attacking any bacteria or viruses that try to cause us harm. NK (natural killer) cells are a component of the immune system that combats such intruders on the front-line. Compared to other immune cells, NK cells act more quickly and aggressively, and tend to attack and destroy virus-infected cells and other abnormal cells.

NK cells are part of the innate immune system that follows the defense mechanisms of the skin and mucosa. When viruses infiltrate the first line of defense and infect host cells, NK cells attack and neutralize them the moment they are detected, rapidly and relentlessly. So, NK cells can be thought of as front-line assault troops. In other words, if the activity level of the NK cells in your body is high (i.e., high NK activity), you are well prepared to prevent various types of diseases, infections or otherwise, from harming you. Thus, NK cells are perhaps the most important component of one’s immunity. NK cells are at the forefront of the host defense mechanism to fight off infections and other foreign agents. They are the main strength of the human body.
