Mannose-binding lectin MBL is an innate immune system pattern recognition protein that kills a wide range of pathogenic microbes through complement activation. Mannose-binding deficiency is common and we suggest that testing for it should be included in the evaluation of children with increased susceptibility to infection.

Mannose-binding lectin MBL is a pattern recognition molecule of the innate immune system. Structurally MBL comprises a cysteine-rich domain at the N-terminus followed by a collagen-like domain a neck region and a carbohydrate recognition domain CRD at the C-terminus Figure 2 Molecules having the collagen-like domain and CRD form the collectin family which includes conglutinin lung surfactant proteins SP-A and SP-D and collectin kidney 1 CL.
