The mannose-binding lectin: a prototypic pattern recognition molecule

Dietary sugars inhibit biologic functions of the pattern recognition molecule, mannose-binding lectin

Mannose-binding lectin (MBL), a mammalian lectin, is a pattern recognition molecule of the innate immune system and recognizes carbohydrates that are exposed on pathogens. In this study, we observed that fructose down regulates MBL-mediated innate immune mechanisms against both influenza A Virus (IAV) and Staphylococcus aureus. These mechanisms include the lectin complement pathway and coagulat...

Mannose-binding lectin: ancient molecule, interesting future.

Five hundred sixty-five million years ago, when the world was empty and barren because animal life had not colonized land yet, a common ancestor that we share with sea squirts (Ascidians) inhabited the seas. One of the genes that we still share with sea squirts today is a gene for mannose-binding lectin (MBL), signifying that this gene has existed for 1565 million years [1, 2] and, thus, has be...

P 144: Sunflower Mannose binding Lectin-Associated Serine Protease Inhibitor-1 (SFMI-1) and -2: Significant Inhibitors of Mannose binding Lectin Pathway which Helps in Multiple Sclerosis Treatment

One of the important parts of innate immunity is complement system that occurs in three different ways; the classic, the alternative and the lectin pathway. The four pattern recognition molecules that have been identified till now are Mannose binding lectin (MBL), a component of lectin pathway, and three ficolins (ficolin1,-2 and -3) which compound to the carbohydrates of the cell surface. MBL ...

Mannose-Binding Lectin-Deficient Mice

A keratin peptide inhibits mannose-binding lectin.

Complement plays a significant role in mediating endothelial injury following oxidative stress. We have previously demonstrated that the lectin complement pathway (LCP), which is initiated by deposition of the mannose-binding lectin (MBL), is largely responsible for activating complement on endothelial cells following periods of oxidative stress. Identifying functional inhibitors that block MBL...
