The complement system is activated cascadically via three distinct major routes: classical pathway (CP), alternative pathway (AP) or lectin pathway (LP). The unique factors associated with the latter are collectins (mannose-binding lectin, collectin-10, collectin-11), ficolins (ficolin-1, ficolin-2, ficolin-3) and proteins of the mannose-binding lectin-associated serine protease (MASP) family 2019-03-01 · Lectin Complement Pathway in Emphysema.

(2)2 University of Colorado Aurora, Colorado. (3)3 Medical University of South Carolina Charleston, South Carolina. 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 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).

We conducted a systematic assessment of the role of complement activation and effector pathways in sarcomas. C3−/−, MBL1 Objective. The pathogenesis of systemic lupus erythematosus (SLE) involves complement activation. Activation of complement through the classical pathway (CP) is well established. However, complement activation through pattern recognition not only happens through the CP, but also through the lectin pathway (LP).
