Mannose-binding lectin (MBL)

Mannose-binding lectin (MBL) is a protein in the blood that plays a key role in the immune system. It detects certain sugar patterns on the surface of many bacteria, viruses, and fungi. Upon recognizing these patterns, MBL activates a series of immune responses that help the body identify and destroy these pathogens. It acts as part of the innate immune system, providing early defense before other immune cells are mobilized. Variations in MBL levels or function can influence susceptibility to infections, making it an important component of immune health.
