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 ...
متن کاملThe differing roles of the classical and mannose-binding lectin complement pathways in the events following skeletal muscle ischemia-reperfusion.
Complement is an important mediator of the injuries observed after skeletal muscle ischemia and subsequent reperfusion. Although the classical pathway had been assumed to be the major pathway of activation leading to injury, the mannose-binding lectin (MBL) pathway might also play a contributing role. In this study, we found that MBL-deficient mice had significant protection after skeletal musc...
متن کاملSmall mannose-binding lectin-associated protein plays a regulatory role in the lectin complement pathway.
Mannose-binding lectin (MBL) and ficolins are pattern recognition proteins acting in innate immunity, and they trigger the activation of the lectin complement pathway through MBL-associated serine proteases (MASPs). Upon activation of the lectin pathway, MASP-2 cleaves C4 and C2. A truncated form of MASP-2, named small MBL-associated protein (sMAP), is also associated with MBL/ficolin-MASP comp...
متن کاملMice deficient in ficolin, a lectin complement pathway recognition molecule, are susceptible to Streptococcus pneumoniae infection.
Mannose-binding lectin (MBL) and ficolin are complexed with MBL-associated serine proteases, key enzymes of complement activation via the lectin pathway, and act as soluble pattern recognition molecules in the innate immune system. Although numerous reports have revealed the importance of MBL in infectious diseases and autoimmune disorders, the role of ficolin is still unclear. To define the sp...
متن کاملThe role of mannose-binding lectin-associated serine protease-3 in activation of the alternative complement pathway.
Mannose-binding lectin (MBL)-associated serine proteases (MASPs) are responsible for activation of the lectin complement pathway. Three types of MASPs (MASP-1, MASP-2, and MASP-3) are complexed with MBL and ficolins in serum. Although MASP-1 and MASP-2 are known to contribute to complement activation, the function of MASP-3 remains unclear. In this study, we investigated the mechanism of MASP-3...
