Complement-Activating Capacity of Autoantibodies Correlates With Disease Activity in Bullous Pemphigoid Patients

open access: yesFrontiers in Immunology, 2018
Background: Bullous pemphigoid is a subepidermal blistering skin disease, associated with autoantibodies to hemidesmosomal proteins, complement activation at the dermal-epidermal junction, and dermal granulocyte infiltration.

Complement Activation Contributes to Severe Acute Respiratory Syndrome Coronavirus Pathogenesis

open access: yesmBio, 2018
The complement system is a critical part of host defense to many bacterial, viral, and fungal infections. It works alongside pattern recognition receptors to stimulate host defense systems in advance of activation of the adaptive immune response. In this

Early complementopathy predicts the outcomes of patients with trauma

open access: yesTrauma Surgery & Acute Care Open, 2019
Background Complementopathy (rapid complement activation and consumption after trauma) has been reported in trauma patients, but the underlying mechanism of these phenomena and their clinical significance remain unclear. This study aimed to determine the

Platelet Mediated Complement Activation [PDF]

open access: yes, 2008
The complement system comprises a series of proteases and inhibitors that are activated in cascade-like fashion during host defense (Makrides 1998). A growing body of evidence supports the hypothesis that immune mechanisms, including complement activation, are involved in inflammatory conditions associated with vascular injury (Acostan et al.

Plasma samples from mouse strains and humans demonstrate different in vitro susceptibilities to complement activation

open access: yesPrecision Nanomedicine, 2018
Complement activation can be evaluated in vitro using plasma or serum from animals and human donors, and in vivo using animal models. Despite many years of research, there is no harmonized approach for the selection of matrix and animal models. Herein,

Modern view on the complement system role in membranous nephropathy

open access: yesТерапевтический архив, 2022
Membranous nephropathy (MN), an immune-mediated glomerular disease, is the most common cause of adult nephrotic syndrome. In MN, proteinuria is developed by podocyte damage due to the complement system activation in response to the subepithelial ...

Pseudo-Anaphylaxis to Polyethylene Glycol (PEG)-Coated Liposomes: Roles of Anti-PEG IgM and Complement Activation in a Porcine Model of Human Infusion Reactions.

open access: yesACS Nano, 2019
Polyethylene glycol (PEG)-coated nanopharmaceuticals can cause mild-to-severe hypersensitivity reactions (HSRs) which can occasionally be life threatening or even lethal. The phenomenon represents an unsolved immune barrier to the use of these drugs, yet

Complement Activation and Inhibition in Wound Healing

open access: yesClinical and Developmental Immunology, 2012
Complement activation is needed to restore tissue injury; however, inappropriate activation of complement, as seen in chronic wounds can cause cell death and enhance inflammation, thus contributing to further injury and impaired wound healing. Therefore,

Activation of human complement system by dextran-coated iron oxide nanoparticles is not affected by dextran/Fe ratio, hydroxyl modifications and crosslinking

open access: yesFrontiers in Immunology, 2016
While having tremendous potential as therapeutic and imaging tools, the clinical use of engineered nanoparticles has been associated with serious safety concerns. Activation of the complement cascade and release of proinflammatory factors C3a and C5a may

Nanoporesize affects complement activation

open access: yesJournal of Biomedical Materials Research Part A, 2008
AbstractIn the present study, we have shown the vast importance of biomaterial nanotexture when evaluating inflammatory response. For the first time in an in vitro whole blood system, we have proven that a small increase in nanoporesize, specifically 180 nm (from 20 to 200 nm), has a huge effect on the complement system.
