We evaluated changes in the complement system resulting from anti-vascular endothelial growth factor (VEGF) in eyes with age-related choroidal neovascularization (CNV) including neovascular age-related macular degeneration, pachychoroid neovasculopathy ...

Drusen complement components C3a and C5a promote choroidal neovascularization [PDF]
Age-related macular degeneration (AMD) is the leading cause of irreversible blindness in industrialized nations, affecting 30–50 million people worldwide. The earliest clinical hallmark of AMD is the presence of drusen, extracellular deposits that accumulate beneath the retinal pigmented epithelium.

Nociceptive sensitization by complement C5a and C3a in mouse [PDF]
Activation of the complement system by injury increases inflammation by producing complement fragments C5a and C3a which are able to recruit and activate immune cells. Complement activation may contribute to pain after inflammation and injury. In this study, we examined whether C5a and C3a elicit nociception when injected into mouse hind paws in vivo ...

Europium-Labeled Synthetic C3a Protein as a Novel Fluorescent Probe for Human Complement C3a Receptor [PDF]
Measuring ligand affinity for a G protein-coupled receptor is often a crucial step in drug discovery. It has been traditionally determined by binding putative new ligands in competition with native ligand labeled with a radioisotope of finite lifetime.

Complement protein C3a enhances adaptive immune responses towards FVIII products
The most serious complication in the treatment of hemophilia A (HA) is the development of factor (F)VIII inhibitors or antidrug antibodies (ADA) occurring in 25-35% of patients with severe HA. The immunological mechanisms underlying the development of ADA against FVIII products have not been completely understood yet.

Complement C3a Regulates Late Asthmatic Response and Airway Hyperresponsiveness in Mice [PDF]
Abstract Allergic asthma is a chronic inflammatory disorder of the airways characterized by biphasic airway obstruction and airway hyperresponsiveness. In this study, we attempted to elucidate the contribution of the complement C3a to these asthmatic symptoms. BALB/c mice sensitized by i.p.

Reduced order modeling and analysis of the human complement system. [PDF]
Complement is an important pathway in innate immunity, inflammation, and many disease processes. However, despite its importance, there are few validated mathematical models of complement activation.

Complement C3 and Activated Fragment C3a Are Involved in Complement Activation and Anti-Bacterial Immunity [PDF]
In the complement system, C3 is a central component in complement activation, immune defense and immune regulation. In all pathways of complement activation, the pivotal step is conversion of the component C3 to C3b and C3a, which is responsible to eliminate the pathogen and opsonization.

Role of Complement Activation in Obliterative Bronchiolitis Post Lung Transplantation [PDF]
Obliterative bronchiolitis (OB) post lung transplantation involves IL-17 regulated autoimmunity to type V collagen and alloimmunity, which could be enhanced by complement activation.

Complement Split Products C3a and C4a in Chronic Lyme Disease [PDF]
AbstractComplement split products C3a and C4a are reportedly elevated in patients with acute Lyme disease. We have now examined these immunologic markers in patients with chronic Lyme disease compared to appropriate disease controls. The study population consisted of 29 healthy controls, 445 patients with chronic Lyme disease, 11 patients with systemic
