The innate immune system recognizes danger …
WebMar 3, 2011 · The lectin pathway (LP) is initiated by carbohydrate pattern recognition receptors such as mannose-binding lectin (MBL) and the ficolins (F) which are in a complex with enzymes known as MBL-associated serine proteases (MASPs). MASP-2 activates the complement system by cleaving both C4 and C2 to form the C4bC2a C3 …
WebThe complement system has about 40 proteins organized in seven functional components . The complement system acts as a sentinel that rapidly and with high specificity detects, traces, targets and eradicates pathogens.
