Effects of a new C5a receptor antagonist on C5a‐ and endotoxin‐ induced neutropenia in the rat [PDF]
A new C5a receptor antagonist, the cyclic peptide Phe‐[Orn‐Pro‐D‐cyclohexylalanine‐Trp‐Arg], (F‐[OPdChaWR]), was tested for its ability to antagonize the neutropenic effects of both C5a and endotoxin in rats. Human recombinant C5a (2 μg kg−1 i.v.) caused rapid neutropenia, characterized by an 83% decrease in circulating polymorphonuclear leukocytes ...

Cloning of the Human C5a Anaphylatoxin Receptor, and More [PDF]
The initial observation in 1973 that the complement C5 activation product, C5a, has the ability to stimulate human neutrophils led to the concept of a specific C5a receptor (1). In the mid-1986, a groundbreaking paper published in Nature announced the cloning of the beta-adrenergic receptor, and for the first time established seven transmembrane (7TM ...

New developments in C5a receptor signaling
Complement activation usually results in the formation of complement fragment 5a (C5a) that interacts with its two receptors, C5aR and C5L2. These receptors belong to the rhodopsin family of G protein-coupled seven transmembrane-containing receptors. C5aR and C5L2 are expressed on/in a wide variety of cells and tissues.

Expression of C5a receptor in osteoblasts
Anaphylatoxin C5a signaling plays an important role in inflammation‐associated bone diseases such as rheumatoid arthritis. However, expression and function of C5a receptor (C5aR) in the osteoblasts are largely unknown. The objective of this study is to determine C5aR expression and its function in the osteoblasts.

New aspects of the C5a receptor
The process of apoptotic cell death for maintenance of cell homeostasis is now believed to be flexible. To examine the mechanism for this flexibility, the process of programmed cell death is sometimes divided into three phases: initiation, effector and execution.
