Sublytic Terminal Complement Components Induce Eryptosis in Autoimmune Haemolytic Anaemia Related to IgM Autoantibodies [PDF]

open access: yes, 2019
BACKGROUND/AIMS: Eryptosis, the suicidal death of red blood cells (RBCs), is characterized by phosphatidylserine (PS) exposure at the cell surface. It can be catalysed by a variety of abnormal conditions and diseases.

The contribution of the alternative pathway in complement activation on cell surfaces depends on the strength of classical pathway initiation

open access: yesClinical & Translational Immunology, 2023
Objectives The complement system is an important component of innate immunity. The alternative pathway (AP) amplification loop is considered an essential feed forward mechanism for complement activation.

Complement C3 serum levels in anorexia nervosa: a potential biomarker for the severity of disease? [PDF]

open access: yes, 2011
BackgroundAnorexia nervosa carries the highest mortality rate of any psychiatric disorder. Even the most critically ill anorexic patients may present with normal 'standard' laboratory values, underscoring the need for a new sensitive biomarker.

Alternative Pathway Dysregulation and the Conundrum of Complement Activation by IgG4 Immune Complexes in Membranous Nephropathy [PDF]

open access: yes, 2016
Membranous nephropathy (MN), a major cause of nephrotic syndrome, is a non-inflammatory immune kidney disease mediated by IgG antibodies that form glomerular subepithelial immune complexes.

Systemic complement activation in age-related macular degeneration. [PDF]

open access: yesPLoS ONE, 2008
Dysregulation of the alternative pathway (AP) of complement cascade has been implicated in the pathogenesis of age-related macular degeneration (AMD), the leading cause of blindness in the elderly. To further test the hypothesis that defective control of

Profiling Complement System Components in Primary CNS Vasculitis

open access: yesCells, 2021
Complement activation has been implicated in the pathogenesis of many vasculitic syndromes such as anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides.

Beyond Binding: The Outcomes of Antibody-Dependent Complement Activation in Human Malaria

open access: yesFrontiers in Immunology, 2021
Antibody immunity against malaria is effective but non-sterile. In addition to antibody-mediated inhibition, neutralisation or opsonisation of malaria parasites, antibody-mediated complement activation is also important in defense against infection ...

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

open access: yes, 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.

Acidosis activates complement system in vitro

open access: yesMediators of Inflammation, 1998
We investigated the in vitro effect of different form s of acidosis (pH 7.0) on the formation of anaphylatoxins C3a and C5a. Metabolic acidosis due to addition of hydrochloric acid (10 μ mol/ml blood) or lactic acid (5.5 μ mol/ml) to heparin blood (N=12)

Essential Role of Complement in Pregnancy: From Implantation to Parturition and Beyond

open access: yesFrontiers in Immunology, 2020
The complement cascade was identified over 100 years ago, yet investigation of its role in pregnancy remains an area of intense research. Complement inhibitors at the maternal-fetal interface prevent inappropriate complement activation to protect the ...
