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.

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.

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.

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.

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.

Serum complement factor C5a in IgG4-related disease [PDF]

Annals of the Rheumatic Diseases, 2019
We read with great interest the correspondence by Umehara et al 1 which discussed the difficulties in the diagnosis of IgG4-related disease (IgG4-RD). They mention that increased IgG4 concentration is not a specific marker for IgG4-RD. Therefore, the markers for the diagnosis and the disease activity of IgG4-RD are demanded. Approximately a quarter of
