Antibody-independent complement activation by myelin via the classical complement pathway [PDF]

Molecular Immunology, 1982
Murine or rabbit whole brain homogenates were shown to activate human complement via the classical pathway by an antibody-independent reaction. This activity required Ca++ ions. Anticomplementary activity in fractionated murine brain was found to reside in the myelin fraction and in purified myelin.

The Functional Amyloid Curli Protects Escherichia coli against Complement-Mediated Bactericidal Activity

Biomolecules, 2018
Escherichia coli strains may be beneficial or pathogenic. Many E. coli strains that cause human disease, especially those responsible for bacteremia and sepsis, express virulence factors that impart resistance to the complement system.

Classical complement pathway activation in membranoproliferative glomerulonephritis

Kidney International, 1976
Levels of components of the classical and alternative complement pathways and the activity of the C3 nephritic factor (C3NeF) were measured in serum specimens from patients with type I (subendothelial deposits) and type II (intramembranous dense deposits) membranoproliferative glomerulonephritis (MPGN) and the results compared with the levels in normal

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 ...

MafB is a critical regulator of complement component C1q [PDF]

, 2017
The transcription factor MafB is expressed by monocytes and macrophages. Efferocytosis (apoptotic cell uptake) by macrophages is important for inhibiting the development of autoimmune diseases, and is greatly reduced in Mafb-deficient macrophages.

Blood platelets activate the classical pathway of human complement [PDF]

Journal of Thrombosis and Haemostasis, 2006
Activation of the complement system plays a key role in inflammation associated with vascular injury. Recently, platelet P-selectin was shown to activate C3 via the alternative pathway of human complement. As platelets also posses binding sites for C1q, the recognition unit of the classical complement pathway, the present study examined classical ...

CLONING OF THE 1.4-kb mRNA SPECIES OF HUMAN COMPLEMENT FACTOR H REVEALS A NOVEL MEMBER OF THE SHORT CONSENSUS REPEAT FAMILY RELATED TO THE CARBOXY TERMINAL OF THE CLASSICAL 150-kDa MOLECULE [PDF]

, 1991
Three factor H mRNA species of 4.3 kb, 1.8 kb, and 1.4 kb are constitutively expressed in human liver. Having previously characterized full-length cDNA clones derived from the 4.3-kb and 1.8-kb factor mRNA, we report here the isolation and eucaryotic ...

Evasion of Classical Complement Pathway Activation on Plasmodium falciparum-Infected Erythrocytes Opsonized by PfEMP1-Specific IgG

Frontiers in Immunology, 2019
Members of the PfEMP1 protein family are expressed on the surface of P. falciparum-infected erythrocytes (IEs), where they contribute to the pathogenesis of malaria and are important targets of acquired immunity.

C1q-targeted inhibition of the classical complement pathway prevents injury in a novel mouse model of acute motor axonal neuropathy [PDF]

, 2016
Introduction Guillain-Barré syndrome (GBS) is an autoimmune disease that results in acute paralysis through inflammatory attack on peripheral nerves, and currently has limited, non-specific treatment options.

Differential Gene Expression in Liver, Gill, and Olfactory Rosettes of Coho Salmon (Oncorhynchus kisutch) After Acclimation to Salinity. [PDF]

, 2015
Most Pacific salmonids undergo smoltification and transition from freshwater to saltwater, making various adjustments in metabolism, catabolism, osmotic, and ion regulation. The molecular mechanisms underlying this transition are largely unknown.
