Mannose-binding Lectin (MBL)

Target
MBL
Molecular classification
Collectin, C-type Lectin, Pattern Recognition Receptor
01

Overview

Mannose-binding lectin (MBL) is a soluble pattern recognition molecule and a key component of the innate immune system. As a collectin, it recognizes carbohydrate patterns on pathogens, activates the lectin pathway of complement, and enhances phagocytosis. MBL deficiency is common and associated with increased infection risk. Genetic variations influence serum levels and function.
