Dengue virus and the complement alternative pathway [PDF]

FEBS Letters, 2020
Dengue disease is an inflammatory‐driven pathology, and complement overactivation is linked to disease severity and vascular leakage. Additionally, dysregulation of complement alternative pathway (AP) components has been described, such as upregulation of complement factor D and downregulation of complement factor H (FH), which activate and inhibit the

Complement factor D is linked to platelet activation in human and rodent sepsis

Intensive Care Medicine Experimental, 2021
Background The complement factor D (CFD) exerts a regulatory role during infection. However, its physiological function in coagulopathy and its impact on the course of an infection remains unclear. Materials Wild-type and CFD-deficient mice (n = 91) were

The Sez6 Family Inhibits Complement by Facilitating Factor I Cleavage of C3b and Accelerating the Decay of C3 Convertases

Frontiers in Immunology, 2021
The Sez6 family consists of Sez6, Sez6L, and Sez6L2. Its members are expressed throughout the brain and have been shown to influence synapse numbers and dendritic morphology. They are also linked to various neurological and psychiatric disorders.

Complement Alternative and Mannose-Binding Lectin Pathway Activation Is Associated With COVID-19 Mortality

Frontiers in Immunology, 2021
BackgroundThe SARS-CoV-2 infection triggers excessive immune response resulting in increased levels of pro-inflammatory cytokines, endothelial injury, and intravascular coagulopathy.

The intersection of complemented submodules is not complemented [PDF]

J. Math. Anal. Appl. 522 (1) (2023) 127002, 2023
We show by (counter)example that the intersection of complemented submodules in a Hilbert $C^*$-module is not necessarily complemented, answering an open question from [MR].

The Complement System and ANCA Associated Vasculitis in the Era of Anti-Complement Drugs

Frontiers in Immunology, 2022
ANCA (anti-neutrophil cytoplasmic antibody)-associated vasculitis (AAV) is the condition in which ANCA, as an autoantibody, is associated with the pathogenesis of vasculitis in small blood vessels, mainly in the ear, nose, throat, kidney, lung, and ...

Diagnosis of complement alternative pathway disorders [PDF]

Kidney International, 2016
Kidney diseases resulting from abnormal control of the complement alternative pathway include atypical hemolytic uremic syndrome, C3 glomerulonephritis, and dense-deposit disease, as well as atypical postinfectious glomerulonephritis. Although clinically diverse, they all result from loss of surface or fluid-phase complement control, caused by acquired

Serological and genetic complement alterations in infection-induced and complement-mediated hemolytic uremic syndrome [PDF]

, 2016
Background: The role of complement in the atypical form of hemolytic uremic syndrome (aHUS) has been investigated extensively in recent years. As the HUS-associated bacteria Shiga-toxin-producing Escherichia coli (STEC) can evade the complement system ...

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.
