Peptide Inhibitor of Complement C1 (PIC1) Rapidly Inhibits Complement Activation after Intravascular Injection in Rats. [PDF]

PLoS ONE, 2015
The complement system has been increasingly recognized to play a pivotal role in a variety of inflammatory and autoimmune diseases. Consequently, therapeutic modulators of the classical, lectin and alternative pathways of the complement system are ...

Different Complement Activation Pathways Underly Cognitive Impairment and Type 2 Diabetes Mellitus Combined With Cognitive Impairment

Frontiers in Aging Neuroscience, 2022
BackgroundThe immune response and the complement system are associated with cognitive impairment and diabetes mellitus, respectively. Activation of the complement system in these diseases occurs mainly through either the classical pathway or the ...

Human pentraxin 3 binds to the complement regulator c4b-binding protein. [PDF]

PLoS ONE, 2011
The long pentraxin 3 (PTX3) is a soluble recognition molecule with multiple functions including innate immune defense against certain microbes and the clearance of apoptotic cells.

A Systematic Investigation on Complement Pathway Activation in Diabetic Retinopathy

Frontiers in Immunology, 2020
The complement system plays a crucial role in retinal homeostasis. While the proteomic analysis of ocular tissues in diabetic retinopathy (DR) has shown the deposition of complement proteins, their exact role in the pathogenesis of DR is yet unclear.

Classical and alternate complement factor overexpression in non-obese weight matched women with polycystic ovary syndrome does not correlate with vitamin D

Frontiers in Endocrinology, 2022
IntroductionWomen with polycystic ovary syndrome (PCOS) exhibit complement factor expression changes that may be obesity-driven rather than an intrinsic facet of PCOS; furthermore, complement changes have been associated with vitamin D deficiency, a ...

Characterization of the Classical Complement Pathway of Rainbow Trout [PDF]

Journal of the Faculty of Agriculture, Kyushu University, 1988
Characteristics of the classical complement pathway (CCP) of rainbow trout Salmo gairdneti was examined using sheep red blood cells sensitized with porgy Pagrms major antibody which is compatible with rainbow trout complement. The rainbow trout CCP showed the highest activity when the reaction was performed at 20-25°C and around pH 7.5, and the ...

Activation of the classical pathway of complement by rheumatoid factors [PDF]

Arthritis & Rheumatism, 1982
AbstractA simple, sensitive solid‐phase radioimmunoassay to quantitate the activation of the classical pathway of complement by rheumatoid factor (RF) is described. RF (purified, in serum or synovial fluid) was bound to reduced and alkylated IgG adsorbed to polyvinyl chloride microtiter plates and reacted with diluted normal human serum (complement ...

DYSFUNCTION OF COMPLEMENT SYSTEM IN FAMILIAL MEDITERRANEAN FEVER

Медицинская иммунология, 2014
. During attacks of familial mediterranean fever (FMF), multiple systemic events are triggered, most of which promote autoinflammatory reactions. A molecular pattern of immune abnormalities in FMF is yet unclear.

Measuring Total Classical Pathway and Activities of Individual Components of the Mouse Complement Pathway

Bio-Protocol, 2021
The complement system is a central component of innate immunity, responsible for recognition and killing of bacteria by tagging invaders through opsonisation, thereby promoting phagocytosis, and by direct lysis.

Activation of the classical complement pathway by mannose-binding protein in association with a novel C1s-like serine protease

Journal of Experimental Medicine, 1992
Serum mannose-binding protein (MBP) is a C-type lectin that binds to terminal mannose and N-acetylglucosamine moieties present on surfaces of certain pathogens and activates the classical complement pathway.
