The Alternative Complement Pathway Is Activated Without a Corresponding Terminal Pathway Activation in Patients With Heart Failure

Frontiers in Immunology, 2021
ObjectiveDysregulation of the complement system has been described in patients with heart failure (HF). However, data on the alternative pathway are scarce and it is unknown if levels of factor B (FB) and the C3 convertase C3bBbP are elevated in these ...

Complement Dysregulation in Obese Versus Nonobese Polycystic Ovary Syndrome Patients

Cells, 2023
Introduction: Upregulation of complement system factors are reported to be increased in polycystic ovary syndrome (PCOS) and may be due to obesity and insulin resistance rather than inherently due to PCOS.

Association of elevated levels of peripheral complement components with cortical thinning and impaired logical memory in drug-naïve patients with first-episode schizophrenia

Schizophrenia, 2023
Schizophrenia has been linked to polymorphism in genes encoding components of the complement system, and hyperactive complement activity has been linked to immune dysfunction in schizophrenia patients.

Characterization of the sheep Complement Factor B gene (CFB) [PDF]

Veterinary Immunology and Immunopathology, 2011
The Complement Factor B gene (CFB) of the alternative complement pathway has been identified in the sheep Major Histocompatibility Complex (MHC) and its genomic sequence determined. CFB is located approximately 600 bp upstream of the complement C2 gene, contains 18 exons, and manifests the domain signature characteristic of CFB protein. Thirteen single

The alternative pathway of complement activation may be involved in the renal damage of human anti-glomerular basement membrane disease. [PDF]

PLoS ONE, 2014
Linear deposition of IgG and complement 3 (C3) along glomerular basement membrane (GBM) is generally revealed in the kidneys of human anti-GBM disease. Our recent studies demonstrated the pathogenic role of complement activation in renal damage of this ...

The outer membrane protease PgtE of Salmonella enterica interferes with the alternative complement pathway by cleaving factors B and H

Frontiers in Microbiology, 2015
The virulence factor PgtE is an outer membrane protease (omptin) of the zoonotic pathogen Salmonella enterica that causes diseases ranging from gastroenteritis to severe enteric fever. It is surface exposed in bacteria that have a short-chain, i.e. rough
