Weak response of porcine C5a receptor towards human C5a in miniature pig endothelial cells and PMNs

, 2007
BACKGROUND: The anaphylatoxin C5a is a potent inflammatory molecule generated during complement activation. Although some reports have implicated C5a in xenograft rejection, to date, the molecular compatibility between human C5a and porcine C5a receptor (

Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

Arthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

Processing of C5a by human polymorphonuclear leukocytes

, 1998
Uptake of human C5a by neutrophils was monitored in vitro using both 125I-labeled and unlabeled C5a. The ligand was internalized by the cells in a dose-dependent manner and maximal binding/uptake was observed after 5 min of incubation.

Complement activation linked to type II interferon signaling in Still disease

Arthritis &Rheumatology, Accepted Article.
Objective Still disease (SD) is an autoinflammatory syndrome characterized by innate immune dysregulation. While complement can drive inflammation, its involvement in SD remains to be defined. Thus, we aimed to assess complement activation in SD. Methods Complement was assessed using transcriptomic, proteomic, and in vitro approaches. RNA sequencing of

C5a stimulation induces caspase-1 activation and mature IL-1β production in human peripheral blood mononuclear cells

Immunological Medicine
The complement component C5a contributes to the recruitment of immune cells to inflamed tissues and local inflammation. The proinflammatory cytokine interleukin (IL)-1β is also related to inflammatory disorders through inflammasome activation.

Modulation of C5a–C5aR1 signaling alters the dynamics of AD progression

Journal of Neuroinflammation, 2022
Background The complement system is part of the innate immune system that clears pathogens and cellular debris. In the healthy brain, complement influences neurodevelopment and neurogenesis, synaptic pruning, clearance of neuronal blebs, recruitment of ...

Analysis of the Interaction of Human C5a and C5a des Arg with Human Monocytes and Neutrophils: Flow Cytometric and Chemotaxis Studies [PDF]

, 1989
C5a and C5a des Arg are potent complement-derived mediators that bind receptors on peripheral blood leukocytes and tissue-specific cellular elements to elicit and amplify inflammatory and immunomodulatory reactions.

Navigating adverse immunostimulation: A practical guide for clinical researchers

British Journal of Clinical Pharmacology, EarlyView.
Problem Setting As drug development moves towards more complex products, early clinical development programmes are increasingly hampered by unwanted and/or unexpected activation of the immune system (adverse immune stimulation, AIS). Solution At the Centre for Human Drug Research, we have introduced standardized procedures to make AIS manageable, while

The relationship of anti-phospholipase A2 receptor antibody and C5a complement with disease activity and short-term outcome in idiopathic membranous nephropathy

Journal of the Formosan Medical Association, 2019
Background: The binding of anti-phospholipase A2 receptor (anti-PLA2R) antibody to podocyte and complement activation is the mechanisms of idiopathic membranous nephropathy (IMN).
