mannan-binding lectin (MBL), a circulating plasma, acute phase protein of hepatic origins that plays an important role in the innate immune response to infection, because it binds to carbohydrates on bacteria, and subsequently activates the complement pathway. circulating plasma, acute phase protein of hepatic origins that plays an important role in the innate immune response to infection, because it binds to carbohydrates on bacteria, and subsequently activates the complement pathway.
LOS sialylation appears to be an important determinant of MBL binding to N. meningitidis and can modulate complement-dependent killing of the bacterium. These findings could explain the observed susceptibility to meningococcal disease of individuals genetically deficient in MBL
