Human L-Ficolin (Ficolin-2) and Its Clinical Significance
Human L-ficolin (P35, ficolin-2) is synthesised in the liver and secreted into the bloodstream where it is one of the major pattern recognition molecules of plasma/serum. Like other ficolins, it consists of a collagen-like tail region linked to a fibrinogen-related globular head; a basic triplet subunit arises via a collagen-like triple helix, and this then forms higher multimers (typically a 1...
متن کاملEvaluation of Ficolin-3 (FCN3) 1637delC (rs28357092) Frameshift Mutation in Iranian Type 2 Diabetic Subjects
Background and Aims: Ficolins are proteins that bind to carbohydrates, act as opsonins and play an important role in innate immunity. Polymorphism in ficolin-3 gene (FCN3) can lead to complement deficiency and increase the risk of some disorders such as diabetes. The aim of this study was to investigate the frequency of FCN3+1637delC as a single nucleotide polymorphism in this gene in healthy a...
متن کاملL-ficolin and H-ficolin in patients with Familial Mediterranean fever
In the present study we performed comparative determination of the blood levels of L-ficolin and H-ficolin, opsonins and the initial components of the complement lectin pathway, in patients with Familial Mediterranean fever (FMF) in attack and attack-free periods and healthy subjects. In addition, in all study subjects serum levels of IL-1b and and total leukocyte count (TLC) were determined. F...
متن کاملFunctional Analysis of Ficolin-3 Mediated Complement Activation
The recognition molecules of the lectin complement pathway are mannose-binding lectin and Ficolin -1, -2 and -3. Recently deficiency of Ficolin-3 was found to be associated with life threatening infections. Thus, we aimed to develop a functional method based on the ELISA platform for evaluating Ficolin-3 mediated complement activation that could be applicable for research and clinical use. Bovi...
متن کاملHistidine-regulated activity of M-ficolin.
Human M-ficolin is a pathogen-associated molecular recognition molecule in the innate immune system, and it binds to some sugars, such as GlcNAc (N-acetylglucosamine), on pathogen surfaces. From previous structural and functional studies of the FD1 (M-ficolin fibrinogen-like domain), we proposed that the ligand-binding region of FD1 exists in a conformational equilibrium between active and non-...
