inducible nitric oxide synthase

Inducible nitric oxide synthase (iNOS) is an enzyme in the immune system that produces nitric oxide, a signaling molecule that helps the body fight infections and destroy harmful microbes. When the immune system detects an invader, iNOS is activated to generate nitric oxide, which can kill bacteria, viruses, and other pathogens. This process is a crucial part of the body's defense mechanism, especially during inflammation or infection. However, excessive or uncontrolled iNOS activity can also contribute to tissue damage and inflammation, making it an important focus in understanding immune responses and inflammatory diseases.
