Expression of the anaphylatoxin C5a receptor in non-myeloid cells

Molecular Immunology, 1999
C5, a 74 amino acid peptide cleaved from the complement protein C5, represents the most potent anaphylatoxin and possesses inflammatory as well as immunomodulatory activities. In the past, expression of the receptor for the anaphylatoxin C5a (C5aR) has been thought to be restricted to cells of myeloid origin.

The chemotactic receptor for human C5a anaphylatoxin

Nature, 1991
Host defence and inflammatory responses are controlled and amplified by receptor-mediated events often initiated by a chemotactic factor that directs the approach of phagocytic cells. Complement receptors CR1 and CR3 are responsible for the phagocytic and adhesive properties of neutrophils, whereas the C5a receptor mediates the pro-inflammatory and ...

Distribution of Rat C5a Anaphylatoxin Receptor

Microbiology and Immunology, 2002
AbstractThe anaphylatoxin, complement 5a (C5a), plays a key role in mediating various inflammatory reactions following complement activation. Several investigators have reported that C5a receptor (C5aR) is expressed in non‐myeloid cells under certain conditions or in different cell lines.

Modeling Molecular Mechanisms of Binding of the Anaphylatoxin C5a to the C5a Receptor

Biochemistry, 2008
This study presents the 3D model of the complex between the anaphylatoxin C5a and its specific receptor, C5aR. This is the first 3D model of a G-protein-coupled receptor (GPCR) complex with a peptide ligand deduced by a molecular modeling procedure analyzing various conformational possibilities of the extracellular loops and the N-terminal segment of ...

C5L2: a controversial receptor of complement anaphylatoxin, C5a

The FASEB Journal, 2012
C5a is the paramount proinflammatory mediator of the complement cascade, and has been previously thought to act only through a single, G‐protein‐coupled, C5a receptor (C5aR; also termed CD88). In 2000, a second C5a receptor, C5L2 (previously known as GPR77), was discovered; yet, despite 12 yr of intensive research, its biological ...
