Potential Mechanisms Underlying TGF-β-mediated Complement Activation in Lung Fibrosis [PDF]

, 2017
While our previous studies suggest that limiting bleomycin-induced complement activation suppresses TGF-β signaling, the specific hierarchical interactions between TGF-β and complement in lung fibrosis are unclear.

Complement activation and increased anaphylatoxin receptor expression are associated with cortical grey matter lesions and the compartmentalised inflammatory response of multiple sclerosis

Frontiers in Cellular Neuroscience, 2023
BackgroundThe extent of cortical pathology is an important determinant of multiple sclerosis (MS) severity. Cortical demyelination and neurodegeneration are related to inflammation of the overlying leptomeninges, a more inflammatory CSF milieu and with ...

Discovery of functionally selective C5aR2 ligands: novel modulators of C5a signalling. [PDF]

, 2016
The complement cascade is comprised of a highly sophisticated network of innate immune proteins that are activated in response to invading pathogens or tissue injury. The complement activation peptide, C5a, binds two seven transmembrane receptors, namely

Molecular Cloning and Characterization of the Human Anaphylatoxin C3a Receptor

Journal of Biological Chemistry, 1996
In a human neutrophil cDNA library, an orphan G-protein-coupled receptor, HNFAG09, with 37% nucleotide identity to the C5a receptor (C5a-R, CD88) was identified. A novel feature of this gene, unlike C5a-R and other G-protein-coupled receptors, is the presence of an extraordinarily large predicted extracellular loop comprised of in excess of 160 amino ...

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

Renal C3 complement component: feed forward to diabetic kidney disease [PDF]

, 2015
BACKGROUND: Diabetic nephropathy is the main cause of end-stage renal disease and has reached epidemic proportions. METHODS: Comprehensive genomic profiling (RNAseq) was employed in the ZS (F1 hybrids of Zucker and spontaneously hypertensive heart ...

Adverse immunostimulation in early phase clinical trials: Key findings and recommendations based on the investigator's clinical experience

British Journal of Clinical Pharmacology, EarlyView.
Problem setting The emergence of therapeutic proteins has coincided with an increase of acute adverse immunostimulation (AIS). AIS has occured in clinical trials despite compliance with regulatory guidelines on preclinical evaluation and its incidence is anticipated to increase even further.

Follicular fluid C3a-peptide promotes oocyte maturation through F-actin aggregation

BMC Biology, 2023
Background Immature cumulus-oocyte complexes are retrieved to obtain mature oocytes by in vitro maturation (IVM), a laboratory tool in reproductive medicine to obtain mature oocytes. Unfortunately, the efficiency of IVM is not satisfactory. To circumvent

Human monocyte‐derived dendritic cells are chemoattracted to C3a after up‐regulation of the C3a receptor with interferons

Immunology, 2004
SummaryThe anaphylatoxin C3a is an important inflammatory mediator in the innate and adaptive immune systems. Recent reports in various animal models have fostered the role of C3a in mediating allergic reactions such as pulmonary allergies. However, data in humans are limited and the cellular targets for C3a are not fully understood.

Inflammatory kidney injury in trichloroethylene hypersensitivity syndrome mice: Possible role of C3a receptor in the accumulation of Th17 phenotype.

Ecotoxicology and Environmental Safety, 2019
Trichloroethylene (TCE) is a common organic solvent which can cause TCE hypersensitivity syndrome (THS) in exposure workers. THS is an adverse skin disorder with severe inflammatory kidney damage.
