However, complement activation through pattern recognition not only happens through the CP, but also through the lectin pathway (LP). We investigated the hypothesis that the LP is activated in SLE and involved in the 2002-05-01 · The lectin-complement pathway--its role in innate immunity and evolution. Fujita T , Matsushita M , Endo Y Immunol Rev , 198:185-202, 01 Apr 2004 Mannose-binding lectin (MBL), a serum lectin specific for mannose or N-acetylglucosamine (GlcNAc), which contains both a collagen-like domain and a carbohydrate-recognition domain (CRD), plays a role in innate immunity by acting as an opsonin and activating complement in association with MBL-associated serine protease (MASP) via the lectin pathway. Endogenous animal lectins, a class of proteins, may perceive non-self glycans found on microorganisms. Serum mannose-binding lectin (sMBL), as a part of the innate immune framework, recognizes a wide range of microbial microorganisms and activates complement cascade via an antibody-independent pathway. MBL binding activates complement.
Activation of complement unfolds along three different complement activation pathways depending on the nature of the pathogen: the classical pathway, the lectin pathway, and the alternative pathway. lectin (LP, activated on recognition of carbohydrate pat-terns), alternative (constitutively active and working as an amplifying loop of complement) and extrinsic (activated by tissue factor, and thrombin) pathways, all generat-ing cleaved active fragments by cascade-like proteolytic reactions. 6,8 2. Complement Lectin Pathway (CLP) Activation. The lectin pathway is initiated when MBL (mannan-binding lectin) or ficolins (L-H-M) bind to patterns of carbohydrates [1–3] or acetyl groups on the surface of protozoan, virus, fungi, or bacteria .

The lectin complement pathway is initiated by microorganism-bound MBL as it associates with two human MBL-associated serine proteases (MASP-1 and -2) that cleave and activate C4 and C2. MASP-1 and MASP-2 are similar to C1r and C1s, respectively, and MBL is similar to C1q. The lectin pathway activates C3 convertase by using a Lectin. Lectin is a special protein that binds to specific carbohydrates. When macrophages ingest viruses, bacteria and other foreign material they release the cytokines. These cytokines stimulate liver cells to secrete mannose-binding protein (MBP), a lectin for mannose. Of the five different lectin pathway recognition molecules in human serum, only L-ficolin and collectin 11 activate complement on pneumococci.
This pathway involves complement components C1, C2 and C4. · Alternative Pathway · Mannose-binding Lectin Pathway. Dec 24, 2002 and the mannose-binding lectin (MBL) pathways (2). There is strong evidence that the complement system is important for innate immunity to

The lectin-complement pathway--its role in innate immunity and evolution Innate immunity was formerly thought to be a non-specific immune response characterized by phagocytosis. However, innate immunity has considerable specificity and is capable of discriminating between pathogens and self.

Complement Pathway, Mannose-Binding Lectin Komplementaktivering, mannosbindande lektin Svensk definition. Komplementaktivering utlöst av samverkan mellan mikrobiella polysackarider och mannosbindande lektin i serum, vilket leder till aktivering av mannosbindande proteinassocierade serinproteaser (MASP). The three pathways, designated classical, lectin and alternative pathway, converge at a central component into a final common pathway. That is activation of C3 leading to formation of C3a and C3b. This cleavage activates the terminal complement pathway leading to eventually the formation of the terminal C5b-9 complement complex (TCC). Click the image above or here to open this pathway in the Pathway Browser Activation of the lectin pathway (LP) is initiated by Mannose-binding lectin (MBL), the hetero-complex CL-LK formed from COLEC11 (Collectin liver 1, CL-L1) and COLEC10 (Collectin … Here we investigated the role of a central humoral component of innate immunity, the lectin pathway of complement, in recognition of mitochondria in vitro and in vivo.
