Classical complement pathway factor alterations in narcolepsy
Acta Neuropsychiatrica, 2022AbstractObjective:Narcolepsy is a chronic sleep disorder long hypothesised to be an autoimmune disease. Complement-mediated immune mechanisms have not been investigated in detail in narcolepsy. Our aim was to establish the significance of classical pathway activation in narcolepsy.Methods:Sera of 42 narcolepsy patients and 26 healthy controls were ...

Classical pathway complement activity in schizophrenia
Neuroscience Letters, 2005There is considerable evidence to suggest a role for complement in the pathogenesis of schizophrenia, but the data related to the classical pathway complement activity in patients with schizophrenia are conflicting. In the present study, the total hemolytic activity of the complement and the activities of individual complement components, C1, C2, C3 ...

Effect of Concanavalin A on the Classical Complement Pathway
The Journal of Immunology, 1977Abstract Lysis of sheep erythrocytes (E) sensitized with anti-Forssman antiserum (EA) is inhibited by the action of concanavalin A (Con A) on whole guinea pig complement (GPC). The degree of inhibition observed for a given quantity of GPC was dependent on the Con A concentration.

Control of the classical and the MBL pathway of complement activation
Molecular Immunology, 2000The activation of complement via the mannan-binding lectin (MBL) pathway is initiated by the MBL complex consisting of the carbohydrate binding molecule, MBL, two associated serine proteases, MASP-1 and MASP-2, and a third protein, MAp19. In the present report we used an assay of complement activation specifically reflecting the physiological activity ...

Interaction of fucoidan with the proteins of the complement classical pathway
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2003Fucoidan inhibits complement by mechanisms that so far remain to be unraveled, and the objective of this work was to delineate the mode of inhibition by this sulfated polysaccharide. For that purpose, low molecular weight fractions of algal (Ascophyllum nodosum) fucoidan containing the disaccharide unit [-->3)-alpha-L-Fuc(2SO3(-))-(1-->4)-alpha-L-Fuc(2,

A novel ELISA for the evaluation of the classical pathway of complement
Journal of Immunological Methods, 1998Assessment of the overall function of the classical pathway of complement is traditionally performed by the hemolytic titration assay CH50. In the present study, we established a novel method for the quantitation of complement activity by measuring the deposition of C1q, C4, C3 and C9 on solid-phase IgM by an enzyme-linked immunosorbent assay (ELISA ...

Activation of the classical complement pathway by BioRex-70
Immunology Letters, 1987The cation exchange resin BioRex-70 was able to activate the classical complement pathway in human serum at 37 degrees C over the resin concentration range 0-5% (v/v). Using zymosan-treated human serum, it was found that the activation proceeded as far as complement protein C3.
