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,

An immunofluorescence assay for complement activation by the classical pathway
Journal of Immunological Methods, 1981The functional integrity of classical complement pathway components was determined by an immunofluorescence (IFL) assay based on the capacity of cytoskeletal intermediate filaments (IMF) to bind C1q and to activate the complement pathway. The assay uses IMF-rich capillary endothelium of human term placentae as complement-activating substrate.

In this chapter, I introduce a number of important aspects of intracellular signaling pathways related to the protection and degeneration in cells, especially neurons, under physiological and pathological conditions. Extracellular stimuli activate intracellular signaling pathways by receptor- and/or channel-mediated manner or simple diffusion across ...

Targetable molecular pathways in classical Hodgkin's lymphoma
Expert Opinion on Investigational Drugs, 2011most patients with classical Hodgkin's lymphoma (cHL) are cured by stage-adapted multimodal regimens. However, some will suffer from refractory disease or experience a relapse. Furthermore, late toxicity due to aggressive chemotherapy and/or radiotherapy has become an increasing problem in long-term survivors.

Introduction While it might appear that the nineteenth-century physics presented in this chapter has no place in a topic as quantum mechanically oriented as atomic physics, this is simply not the case. The purpose of this first chapter is to try to convince the readers that the material learned in their early years of studying physics is not disjoint

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 ...

Classical pathway complement activation in Kawasaki syndrome
Journal of Allergy and Clinical Immunology, 1994In this study the complement breakdown products C3d, C4d, Bb and membrane attack complex were measured in plasma of patients with Kawasaki syndrome. The results suggested strong activation of the classical activation pathway. However, there was no significant decrease in hemolytic titer or in the concentrations of the intact proteins C3, C4, and B. The

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.

Classical pathway deficiencies – A short analytical review
Molecular Immunology, 2015Deficiencies in the classical pathway of complement activation have some common features but show also great differences. Deficiencies of each of the components (C1q, C1s, C1r, C4 and C2) imply increased susceptibility to bacterial infections. They are also associated with increased risk to develop systemic lupus erythematosus where deficiency of C1q ...

Activation of the Classic and Alternate Complement Pathways by Endotoxin
The Journal of Immunology, 1974Abstract The ability of bacterial endotoxin (LPS) to activate the complement system was studied in guinea pig serum (GPS). In serum chelated with ethyleneglycol tetraacetic acid (EGTA) 10 mM, which permits alternate complement pathway activation but inhibits classic complement pathway activation, lysis of LPS-coated sheep erythrocytes (E-
