Hyperfunctional complement C3 promotes C5-dependent atypical hemolytic uremic syndrome in mice [PDF]

, 2019
Atypical hemolytic uremic syndrome (aHUS) is frequently associated in humans with loss-of-function mutations in complement-regulating proteins or gain-of-function mutations in complement-activating proteins.

Insights Into Enhanced Complement Activation by Structures of Properdin and Its Complex With the C-Terminal Domain of C3b

Frontiers in Immunology, 2019
Properdin enhances complement-mediated opsonization of targeted cells and particles for immune clearance. Properdin occurs as dimers, trimers and tetramers in human plasma, which recognize C3b-deposited surfaces, promote formation, and prolong the ...

Variability and action mechanism of a family of anticomplement proteins in Ixodes ricinus. [PDF]

PLoS ONE, 2008
BACKGROUND: Ticks are blood feeding arachnids that characteristically take a long blood meal. They must therefore counteract host defence mechanisms such as hemostasis, inflammation and the immune response.

The tumour microenvironment links complement system dysregulation and hypoxic signalling. [PDF]

, 2018
The complement system is an innate immune pathway typically thought of as part of the first line of defence against "non-self" species. In the context of cancer, complement has been described to have an active role in facilitating cancer-associated ...

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 ...

Complement Initiation Varies by Sex in Intestinal Ischemia Reperfusion Injury

Frontiers in Immunology, 2021
Intestinal ischemia reperfusion (IR)-induced tissue injury represents an acute inflammatory response with significant morbidity and mortality. The mechanism of IR-induced injury is not fully elucidated, but recent studies suggest a critical role for ...

Modulation of porcine intestinal epitheliocytes immunetranscriptome response by Lactobacillus jensenii TL2937 [PDF]

, 2016
In order to evaluate probiotic strains applicable for the beneficial immunomodulation of the porcine gut (immunobiotics), we previously developed a porcine intestinal epitheliocyte cell line (PIE cells).

Urinary Properdin and sC5b-9 Are Independently Associated With Increased Risk for Graft Failure in Renal Transplant Recipients

Frontiers in Immunology, 2019
The pathophysiology of late kidney-allograft failure remains complex and poorly understood. Activation of filtered or locally produced complement may contribute to the progression of renal failure through tubular C5b-9 formation.

FHR-1 binds to C-reactive protein and enhances rather than inhibits complement activation [PDF]

, 2017
Factor H (FH)-related protein 1 (FHR-1) is one of the five human factor H-related proteins, which share sequence and structural homology with the alternative pathway complement inhibitor FH.

Human Properdin Modulates Macrophage: Mycobacterium bovis BCG Interaction via Thrombospondin Repeats 4 and 5

Frontiers in Immunology, 2018
Mycobacterium tuberculosis can proficiently enter macrophages and diminish complement activation on its cell surface. Within macrophages, the mycobacterium can suppress macrophage apoptosis and survive within the intracellular environment. Previously, we
