Mannan-binding Lectin

Mannose-binding protein (MBP) or lectin (MBL) is a lectin that acts as an adsorbent in innate immunity and through the lectin-complement pathway. MBL consists of subunits with an oligomeric structure (400-700 kDa) containing three probably identical peptide chains of approximately 30 kDa.

Technology: Gel-filtration Chromatography

Journal: Marine Biotechnology

IF: 3.152

Published: 2013

Results: In this study, a mannan-specific lectin ((MBL-SN)) was isolated from the sea urchin plasma using a combination of gel filtration chromatography, affinity chromatography, and ion exchange chromatography. The physicochemical characterization showed that the molecular weight of the lectin was about 34 kDa, and it belonged to the C-type mannose-specific lectin. It had a common folding pattern compared to the existing three-dimensional structure of C-type mannose-specific lectins.

As Receptors for Receptor-Mediated Targeting

  • MBL is a circulating protein that functions as a soluble pattern-recognition molecule in innate immunity.
  • MBL spots high-mannose forms of glycans in foreign microorganisms or plant pests.
  • MBL distinguishes carbohydrate structures expressed on the surfaces of multiple bacteria; MBL triggers carbohydrate-mediated complement activation.
  • MBL has complement-dependent bactericidal action.

Healing Applications of MBL

  • MBL replacement strategy has been applied to treat radiation-induced chronic ulcers.
  • MBL is shown to have a major impact on the complement system in the remodeling process of bone healing and in the pathophysiology of diabetic nephropathy.
