C5a enhances dysregulated inflammatory and angiogenic responses to malaria in vitro: potential implications for placental malaria. [PDF]

PLoS ONE, 2009
Placental malaria (PM) is a leading cause of maternal and infant mortality. Although the accumulation of parasitized erythrocytes (PEs) and monocytes within the placenta is thought to contribute to the pathophysiology of PM, the molecular mechanisms ...

A pro-inflammatory role of C5L2 in C5a-primed neutrophils for ANCA-induced activation. [PDF]

PLoS ONE, 2013
BACKGROUND:The complement system is crucial for the development of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). In particular, C5a and its receptor on neutrophils, CD88, play a central role.

Interleukin-33 Amplifies Human Mast Cell Activities Induced by Complement Anaphylatoxins

Frontiers in Immunology, 2021
Both, aberrant mast cell responses and complement activation contribute to allergic diseases. Since mast cells are highly responsive to C3a and C5a, while Interleukin-33 (IL-33) is a potent mast cell activator, we hypothesized that IL-33 critically ...

Complement anaphylatoxin C5a neuroprotects through regulation of glutamate receptor subunit 2 in vitro and in vivo

Journal of Neuroinflammation, 2008
Background The complement system is thought to be involved in the pathogenesis of numerous neurological diseases. We previously reported that pre-treatment of murine cortico-hippocampal neuronal cultures with the complement derived anaphylatoxin C5a ...

A peptide mimic of the chemotaxis inhibitory protein of Staphylococcus aureus: towards the development of novel anti-inflammatory compounds [PDF]

, 2010
Complement factor C5a is one of the most powerful pro-inflammatory agents involved in recruitment of leukocytes, activation of phagocytes and other inflammatory responses.

Ischemia and reperfusion injury in kidney transplantation : relevant mechanisms in injury and repair [PDF]

, 2020
Ischemia and reperfusion injury (IRI) is a complex pathophysiological phenomenon, inevitable in kidney transplantation and one of the most important mechanisms for non- or delayed function immediately after transplantation.

Prostate cancer C5a receptor expression and augmentation of cancer cell proliferation, invasion, and PD‐L1 expression by C5a

The Prostate, 2020
The treatment of castration‐resistant prostate cancer (CRPC) is a urological issue. Recent studies have revealed cancer promotion via the C5a–C5a receptor (C5aR) system.

HSP90-Mediates Liraglutide Preconditioning-Induced Cardioprotection by Inhibiting C5a and NF-κB

Journal of Investigative Surgery, 2022
Objective We previously showed that HSP90 is involved in postconditioning cardioprotection by inhibiting complement C5a. Here, we investigated whether HSP90-mediated C5a/NF-κB inhibition is responsible for the cardioprotection conferred by liraglutide ...

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

Pharmacological Stimulation of Phagocytosis Enhances Amyloid Plaque Clearance; Evidence from a Transgenic Mouse Model of ATTR Neuropathy

Frontiers in Molecular Neuroscience, 2017
Hereditary ATTR V30M amyloidosis is a lethal autosomal dominant sensorimotor and autonomic neuropathy caused by deposition of aberrant transthyretin (TTR).
