Frontiers in Immunology, 2016 The complement system plays an important role in the innate and acquired immune response against pathogens. It consists of more than 30 proteins found in soluble form or attached to cell membranes. Most complement proteins circulate in inactive forms and

Poultry Science, 1989 Complement activity in turkey serum was examined by using inhibitors or activators of mammalian complement. Hemolytic test systems using sheep red blood cells sensitized with specific antibody (SSRBC) and horse red blood cells (HRBC) were developed to measure residual complement activity of turkey sera treated with the various inhibitors or activators.

Deficient Classical Complement Pathway Activity in Newborn Sera [PDF]
Pediatric Research, 1983 Summary: The bactericidal activity of 20 maternal-neonatal paired sera was assessed employing a clinical type la, group B streptococcal isolate, strain 515, known to be opsonized by the classical complement pathway in a non-antibody dependent fashion.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Facioscapulohumeral muscular dystrophy type 1 (FSHD1) is a progressive neuromuscular disorder with no approved treatments. Identifying reliable biomarkers is critical to monitor disease severity, activity, and progression. Interleukin‐6 (IL‐6) has been proposed as a candidate biomarker, but longitudinal validation is limited ...

Interaction of purified lipoteichoic acid with the classical complement pathway [PDF]
Infection and Immunity, 1986 Glycerophosphate-containing lipoteichoic acids (LTAs) interact with the first component of the classical complement pathway (C1). This resulted in the activation of the classical complement pathway in serum, shown by the consumption of C1, C2, and C4. The dose-dependent interaction of LTAs with purified C1 and C1q was dependent on the negative charges ...

Decreased Serum 5‐HT: Clinical Correlates and Regulatory Role in NMJ of MG
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Although 5‐Hydroxytryptamine (5‐HT) indirectly stimulates muscle contraction and participates in regulating Acetylcholine receptor (AChR) cluster homeostasis in cellular, animal, and clinical studies, evidence regarding its potential to modulate muscle contraction in myasthenia gravis (MG) remains limited.

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.

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.

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.

A Spatially Resolved View on the Aging Substantia nigra: An Exploratory Proteomic Study
Advanced Biology, EarlyView.Although aging is the most important risk factor for several neurodegenerative diseases, the molecular effects of physiological aging are still understudied. By applying spatially‐resolved proteomic analyses of the human substantia nigra pars compacta, alterations in vesicular trafficking and mitochondrial proteins are observed, as well as reduced ...
