The role of C5a receptors in autoimmunity

open access: yesImmunobiology, 2023
The complement system is an essential component of the innate immune response and plays a vital role in host defense and inflammation. Dysregulation of the complement system, particularly involving the anaphylatoxin C5a and its receptors (C5aR1 and C5aR2), has been linked to several autoimmune diseases, indicating the potential for targeted therapies ...

Regulation of cAMP responses by the G12/13 pathway converges on adenylyl cyclase VII [PDF]

open access: yes, 2008
Regulation of intracellular cyclic adenosine 3’, 5’-monophosphate (cAMP) by multiple pathways enables differential function of this ubiquitous second messenger in a context dependent manner.

Increased C5a receptor expression in sepsis [PDF]

open access: yesJournal of Clinical Investigation, 2002
Excessive production of the complement activation product C5a appears to be harmful during the development of sepsis in rodents. Little is known about the role of the C5a receptor (C5aR) and its presence in different organs during sepsis. Using the cecal ligation/puncture (CLP) model in mice, we show here that C5aR immunoreactivity was strikingly ...

Netrin-1 Reduces Monocyte and Macrophage Chemotaxis towards the Complement Component C5a.

open access: yesPLoS ONE, 2016
Netrin-1, acting at its cognate receptor UNC5b, has been previously demonstrated to inhibit CC chemokine-induced immune cell migration. In line with this, we found that netrin-1 was able to inhibit CCL2-induced migration of bone marrow derived ...

NOD2-mediated suppression of CD55 on neutrophils enhances C5a generation during polymicrobial sepsis. [PDF]

open access: yesPLoS Pathogens, 2013
Nucleotide-binding oligomerization domain (NOD) 2 is a cytosolic protein that plays a defensive role in bacterial infection by sensing peptidoglycans. C5a, which has harmful effects in sepsis, interacts with innate proteins.

Evaluation of the Safety and Efficacy of Avacopan, a C5a Receptor Inhibitor, in Patients With Antineutrophil Cytoplasmic Antibody–Associated Vasculitis Treated Concomitantly With Rituximab or Cyclophosphamide/Azathioprine: Protocol for a Randomized, Double-Blind, Active-Controlled, Phase 3 Trial

open access: yesJMIR Research Protocols, 2019
Background Antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis is a serious, often life-threatening disease. In new-onset disease or a relapse, the standard treatment is immunosuppressive therapy with glucocorticoids; these therapies are ...

Pro-inflammatory regulatory mechanism of C5a/C5aR pathway in GCRV-infected grass carp (Ctenopharyngodon idella)

open access: yesAquaculture Reports, 2023
Death of grass carp (Ctenopharyngodon idella) caused by grass carp reovirus (GCRV) infection severely restricts the development of the grass carp industry.

Antimicrobial peptides and complement in neonatal hypoxia-ischemia induced brain damage [PDF]

open access: yes, 2015
Hypoxic-ischemic encephalopathy (HIE) is a clinical condition in the neonate, resulting from oxygen deprivation around the time of birth. HIE affects 1-5/1000 live births worldwide and is associated with the development of neurological deficits ...

The role of the host—Neutrophil biology

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Systemic inhibition of the membrane attack complex impedes neuroinflammation in chronic relapsing experimental autoimmune encephalomyelitis

open access: yesActa Neuropathologica Communications, 2018
The complement system is a key driver of neuroinflammation. Activation of complement by all pathways, results in the formation of the anaphylatoxin C5a and the membrane attack complex (MAC).
