Membrane assembly of aquaporin-4 autoantibodies regulates classical complement activation in neuromyelitis optica.

Journal of Clinical Investigation, 2019
Neuromyelitis optica (NMO) is an autoimmune CNS disorder mediated by pathogenic aquaporin-4 (AQP4) water channel autoantibodies (AQP4-IgG). Although AQP4-IgG-driven complement-dependent cytotoxicity (CDC) is critical for the formation of NMO lesions, the

Legionella pneumophila lipopolysaccharide activates the classical complement pathway [PDF]

Infection and Immunity, 1992
Legionella pneumophila is a gram-negative bacterium capable of entering and growing in alveolar macrophages and monocytes. Complement and complement receptors are important in the uptake of L. pneumophila by human mononuclear phagocytes. The surface molecules of L. pneumophila that activate the complement system are unknown.

Efgartigimod Combined With Steroid Treatment for HAM/TSP: A Case Report

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT HTLV‐1‐associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a progressive neurological disorder with limited treatment options. We report a 54‐year‐old female with decade‐long, progressive HAM/TSP, previously refractory to rituximab, who experienced worsening spastic paraparesis and neurogenic bladder dysfunction.

Cholesterol Crystals Activate the Lectin Complement Pathway via Ficolin-2 and Mannose-Binding Lectin: Implications for the Progression of Atherosclerosis. [PDF]

, 2016
Cholesterol crystals (CC) play an essential role in the formation of atherosclerotic plaques. CC activate the classical and the alternative complement pathways, but the role of the lectin pathway is unknown.

Preanalytical classical and alternative complement pathway activity loss

Biochemia medica, 2019
Introduction: Complement functional analyses provide insight into the integrity of the entire complement reaction cascade. These tests are suitable for investigating suspected complement deficiencies. Falsely reduced test outcomes may result from preanalytical instabilities of individual complement components.

Stability of C3 Convertase in the Rat Classical Complement Pathway [PDF]

Microbiology and Immunology, 1997
AbstractIt has been reported that rat serum complement causes efficient hemolysis of antibody‐sensitized sheep erythrocytes (EA) at 20 C but not at 37 C. In connection with this, we demonstrated that C3 convertase of rat complement was significantly unstable at 37 C using purified components of rat complement.

Association of Elevated Serum S100A8/A9 Levels and Cognitive Impairment in Patients With Systemic Lupus Erythematosus

Arthritis Care &Research, EarlyView.
Objective Cognitive impairment (CI) is common in patients with systemic lupus erythematosus (SLE). Despite its prevalence, the immune mechanisms are not well understood. We previously reported elevated serum levels of S100A8/A9 and matrix metalloproteinase 9 (MMP‐9) in patients with SLE and CI.

Activation of the classical complement pathway by mannose-binding protein in association with a novel C1s-like serine protease

Journal of Experimental Medicine, 1992
Serum mannose-binding protein (MBP) is a C-type lectin that binds to terminal mannose and N-acetylglucosamine moieties present on surfaces of certain pathogens and activates the classical complement pathway.

LOXHD1 and RHOB Expression by Monocytes Predicts Progressive Systemic Sclerosis associated Interstitial Lung Disease

Arthritis Care &Research, Accepted Article.
Objective A leading cause of death among scleroderma (SSc) patients, interstitial lung disease (ILD) remains challenging to prognosticate. The discovery of biomarkers that accurately determine which patients would benefit from close monitoring and aggressive therapy would be an essential clinical tool.

Non-invasive monitoring of renal transplant recipients: Urinary excretion of soluble adhesion molecules and of the complement-split product C4d [PDF]

, 2003
Background: The number of inducible adhesion molecules known to be involved in cell-mediated allograft rejection is still increasing. In addition, recent data describe complement activation during acute humoral allograft rejection.
