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).

Innate immune response to intramammary infection with Serratia marcescens and Streptococcus uberis [PDF]

, 2004
Streptococcus uberis and Serratia marcescens are Gram-positive and Gram-negative bacteria, respectively, that induce clinical mastitis. Once initial host barrier systems have been breached by these pathogens, the innate immune system provides the next ...

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 ...

Different concentrations of C5a affect human dental pulp mesenchymal stem cells differentiation

BMC Oral Health, 2021
Background During the process of deep decay, when decay approaches the pulp, an immune response is triggered inside the pulp, which activates the complement cascade.

Complement C5a receptors C5L2 and C5aR in renal fibrosis [PDF]

American Journal of Physiology-Renal Physiology, 2018
Complement factor C5a has two known receptors, C5aR, which mediates proinflammatory effects, and C5L2, a potential C5a decoy receptor. We previously identified C5a/C5aR signaling as a potent profibrotic pathway in the kidney. Here we tested for the first time the role of C5L2 in renal fibrosis.

Complement factor C5a induces atherosclerotic plaque disruptions [PDF]

Journal of Cellular and Molecular Medicine, 2014
AbstractComplement factor C5a and its receptor C5aR are expressed in vulnerable atherosclerotic plaques; however, a causal relation between C5a and plaque rupture has not been established yet. Accelerated atherosclerosis was induced by placing vein grafts in male apoE−/− mice.

The complement anaphylatoxin C5a induces apoptosis in adrenomedullary cells during experimental sepsis. [PDF]

PLoS ONE, 2008
Sepsis remains a poorly understood, enigmatic disease. One of the cascades crucially involved in its pathogenesis is the complement system. Especially the anaphylatoxin C5a has been shown to have numerous harmful effects during sepsis.

C5a-C5aR1 Axis Activation Drives Envenomation Immunopathology by the Snake Naja annulifera

Frontiers in Immunology, 2021
Systemic complement activation drives a plethora of pathological conditions, but its role in snake envenoming remains obscure. Here, we explored complement’s contribution to the physiopathogenesis of Naja annulifera envenomation.

Complement C5a-Induced Changes in Neutrophil Morphology During Inflammation. [PDF]

Scand J Immunol, 2017
AbstractThe complement and neutrophil defence systems, as major components of innate immunity, are activated during inflammation and infection. For neutrophil migration to the inflamed region, we hypothesized that the complement activation product C5a induces significant changes in cellular morphology before chemotaxis. Exposure of human neutrophils to

Regulatory effects of C5a on IL-17A, IL-17F, and IL-23

Frontiers in Immunology, 2013
The complement anaphylatoxin, C5a, through binding to its receptors (C5aR or C5L2), has important biological properties for recruitment and activation of phagocytes.
