Complement components are designated by numerals ( C1 - C9 ), by letter symbols (e.g., Complement factor I ( Factor I )), or by trivial names. 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. 2021-03-21 The lectin pathway or lectin complement pathway is a type of cascade reaction in the complement system, similar in structure to the classical complement pathway, in that, after activation, it proceeds through the action of C4 and C2 to produce activated complement proteins further down the cascade. The lectin complement pathway is an essential part of the complement system, which provides an effective defense against invading pathogens and apoptotic cells in an organism.

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 . Complement System · Classical Pathway.

( Alternative Complement Pathway) Inflammation – by attracting macrophages and Se hela listan på microbeonline.com 2012-07-05 · The lectin pathway drives complement deposition on S. pneumoniae Complement deficient sera were used to determine which components contribute to C3b opsonisation of S. pneumoniae. C3b deposition was assayed by ELISA using formalin-fixed bacteria and by FACS analysis using live bacteria. Activation of complement via the lectin pathway is initiated by several pattern-recognition molecules (PRM), complexed with mannose-binding lectin-associated serine proteases (MASP). These PRM are classified into two lectin families: collectins (mannose-binding lectin, MBL; collectin-10, CL-10 and collectin-11, CL-11) and ficolins (ficolin-1, ficolin-2, ficolin-3). Lectins, carbohydrate‐binding proteins, play an important role in innate immunity by recognizing a wide range of pathogens.

Similar to classical pathway, the lectin pathway is also a proteolytic cascade that elicits various effector functions including phagocytosis, cell lysis, inflammation, and guidance of the adaptative immune response. The lectin pathway of the complement is activated when MBL binds to hexoses with carbon 3 and 4 OH groups such as N -acetyl- d-glucosamine, glucose, fucose, and mannose. These sugars are expressed as repetitive O-polysaccharide structures on surfaces of bacteria, yeast, parasites, mycobacteria, and certain viruses. Mannose-binding lectin (MBL), also known as mannan-binding protein (MBP), is a protein that is involved in complement activation via the lectin pathway. The complement system provides immediate defense against infection and has proinflammatory effects.
