Identification and characterization of two mannan-binding lectin associated proteins in lectin complement pathway of grass carp

The lectin pathway of complement activation is an important component of the innate immune response, which must be tightly controlled to maintain immune homeostasis. However, its control mechanisms have not been investigated in detail in bony fish. In this study, we identified and characterized two novel, phylogenetically conserved mannan-binding lectin (MBL)-associated proteins (MAps) of grass carp (Ctenopharyngodon idella), CiMAp27 and...
