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 ...

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

Abstract White adipose tissue (WAT) is a reservoir for various pathogens and their products, such as lipopolysaccharides. Therefore, it must be equipped with a defense mechanism connected with the activation of innate immunity. This explains the phenomenon that adipocytes express components of the classical and alternative complement pathways, which ...

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

Preeclampsia fetuses show an altered profile of endothelial damage and complement biomarkers, like increased adhesion molecules, prothrombotic state, oxidative stress, and reduced complement membrane attack complex deposition on endothelial cells. Abstract Introduction Our objective was to evaluate the endothelial function profile and complement system

Exploring urine:serum fractional excretion ratios as potential biomarkers for lupus nephritis
ObjectivesThe goal of this exploratory study is to determine if urine:serum fractional excretion ratios can outperform the corresponding urinary biomarker proteins in identifying active renal disease in systemic lupus erythematosus (SLE).MethodsThirty ...

Immune thrombocytopenia (ITP) is an autoimmune disorder marked by reduced platelet levels and heightened susceptibility to bleeding resulting from augmented autologous platelet destruction and diminished thrombopoiesis. It is found that the lectin pathway of the complement system, resistin, MIF, and AA metabolism may serve as promising targets for ...
