WebMannan-binding lectin (MBL) is an oligomeric lectin (based on a homotrimeric structural unit) which recognizes neutral sugars (mannose and N -acetylglucosamine) on microbial surface and is involved in innate immunity against infection. Serum purified MBL is a mixture of oligomers with two major forms: MBL-I and MBL-II. WebThe envelope glycoproteins of HCV are heavily glycosylated with a high proportion of high-mannose glycans (HMGs), which serve as a shield against neutralizing antibodies and assist in the interaction with cell-entry receptors. However, there is no approved therapeutic targeting this potentially druggable biomarker. Methods:

MBL belongs to the class of collectins in the C-type lectin superfamily, whose function appears to be pattern recognition in the first line of defense in the pre-immune host. MBL recognizes carbohydrate patterns found on the surface of a large number of pathogenic micro-organisms, including bacteria, viruses, protozoa and fungi. Binding of MBL to a micro-organism results in activation of the lectin pathway of the complement system.
