C5a-C5aR1 axis mediates lung inflammation and fibrosis induced by single-walled carbon nanotubes via promoting neutrophils recruitment

Ecotoxicology and Environmental Safety
A mounting number of studies have been documenting strong pro-inflammatory and pro-fibrotic effects of carbon nanotube (CNT). However, the molecular mechanisms of single-walled CNT (SWCNT)-provoked lung injury remain to be elucidated.

Expression of C5a receptor in osteoblasts

The FASEB Journal, 2008
Anaphylatoxin C5a signaling plays an important role in inflammation‐associated bone diseases such as rheumatoid arthritis. However, expression and function of C5a receptor (C5aR) in the osteoblasts are largely unknown. The objective of this study is to determine C5aR expression and its function in the osteoblasts.

Distinct Gene Expression Profiles of Ara h 2‐Specific B Cells in Desensitization and Tolerance During Peanut Oral Immunotherapy

Allergy, EarlyView.
Gene expression of Ara h 2‐specific B cells over the course of the peanut OIT. Isotype of allergen‐specific B cells changes through OIT towards IgG4. Peanut OIT changes the gene expression of allergen‐specific memory B cells. OIT patients showed increased gene expression for regulatory B cells and immune regulation.

C5a Increases the Injury to Primary Neurons Elicited by Fibrillar Amyloid Beta

ASN Neuro, 2017
C5aR1, the proinflammatory receptor for C5a, is expressed in the central nervous system on microglia, endothelial cells, and neurons. Previous work demonstrated that the C5aR1 antagonist, PMX205, decreased amyloid pathology and suppressed cognitive ...

Nomenclature on Immune‐Mediated Drug Reactions: An EAACI Position Paper

Allergy, EarlyView.
ABSTRACT Over the past several decades, there have been significant advances in our understanding of both immunological and pharmacological mechanisms of adverse drug reactions (ADRs). Immune‐mediated drug reactions (IMDRs) represent a small proportion of ADRs and are caused by a pathological activation of the immune system or inflammatory pathways ...

Modulation of ligand selectivity by mutation of the first extracellular loop of the human C5a receptor

, 2001
The cyclic C5a receptor antagonist, phenylalanine [L-ornithine-proline-D-cyclohexylalanine-tryptophan-arginine] (F-[OPchaWR]), has similar to 1000-fold less affinity for the C5a receptor (C5aR) on murine polymorphonuclear leukocytes than on human ...

Complement receptor C3aR marks heterogeneous tumor‐associated macrophage states associated with improved survival in IDH‐wildtype glioblastoma

Brain Pathology, EarlyView.
C3aR expression in IDH‐wildtype glioblastoma is predominantly associated with the myeloid/macrophage compartment and heterogeneous macrophage states. C3aR‐high tumors are enriched among MGMT promoter‐methylated tumors and show improved overall survival, although the prognostic association requires independent validation.

Cloning and functional expression of the canine anaphylatoxin C5a receptor. Evidence for high interspecies variability.

, 1992
A cDNA clone, DTJP03, encoding an orphan receptor, was isolated from a canine thyroid library, and found to exhibit 68.6% amino-acid identity with the recently described human C5a receptor.

Expression of complement C5a receptor and the viability of 4T1 tumor cells following agonist–antagonist treatment

, 2016
Background: Complement system is theoretically believed to halt the progression of tumor by the activity of C5a/CD88. Protein C5a is a potent pro.inflammatory mediator that activates the complement system by binding to its receptor.
