cDNA Cloning and Characterization of Rat C5a Anaphylatoxin Receptor [PDF]

Microbiology and Immunology, 1997
AbstractActivation of the complement cascade plays an esssential role in the early stages of inflammation. C5a and its receptor are particularly active in anaphylaxis. To determine the pathological roles played by C5a and C5a receptor (C5aR) in rats, we cloned C5aR cDNA and analyzed distribution of its mRNA in various organs including lung from an LPS ...

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 ...

Cytokine and Complement Response in the Glaucomatous βB1-CTGF Mouse Model

Frontiers in Cellular Neuroscience, 2021
Glaucoma is a complex neurodegenerative disease leading to a loss of retinal ganglion cells (RGCs) and optic nerve axons. An activation of the complement system seems to contribute to cell loss in this disease.

Cloning and characterization of the guinea pig C5a anaphylatoxin receptor: interspecies diversity among the C5a receptors [PDF]

International Immunology, 1998
The anaphylatoxin C5a receptor (C5aR, CD88 in man) plays a prominent role in mediating inflammatory and host defense processes. Direct evidence of C5aR involvement in host defense mechanisms was demonstrated recently using C5aR knockout mice. Mice deficient in C5aR were unable to clear intrapulmonary-instilled bacteria. The guinea pig system is perhaps

Complement C5a Induces Pro-inflammatory Microvesicle Shedding in Severely Injured Patients

Frontiers in Immunology, 2020
Initially underestimated as platelet dust, extracellular vesicles are continuously gaining interest in the field of inflammation. Various studies addressing inflammatory diseases have shown that microvesicles (MVs) originating from different cell types ...

Sphingosine kinase 1 mediation of expression of the anaphylatoxin receptor C5L2 dampens the inflammatory response to endotoxin.

PLoS ONE, 2012
The complement anaphylatoxin C5a has a pathogenetic role in endotoxin-induced lung inflammatory injury by regulating phagocytic cell migration and activation.

Characterization of a Receptor for C5a Anaphylatoxin on Human Eosinophils

Journal of Biological Chemistry, 1989
The complement anaphylatoxin peptide C5a is well known to activate human polymorphonuclear leukocytes through receptor-mediated processes. C5a has also been reported to activate eosinophils for both chemotaxis and hexose uptake. We characterized the receptor molecule for human C5a on human eosinophils and compared it with the receptor on human ...

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

Acta 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).

Treatment of Rare Inflammatory Kidney Diseases: Drugs Targeting the Terminal Complement Pathway

Frontiers in Immunology, 2020
The complement system comprises the frontline of the innate immune system. Triggered by pathogenic surface patterns in different pathways, the cascade concludes with the formation of a membrane attack complex (MAC; complement components C5b to C9) and ...

Bacterial polyphosphates induce CXCL4 and synergize with complement anaphylatoxin C5a in lung injury

Frontiers in Immunology, 2022
Polyphosphates are linear polymers of inorganic phosphates that exist in all living cells and serve pleiotropic functions. Bacteria produce long-chain polyphosphates, which can interfere with host defense to infection.
