We recently reported that not only lymphoid cells, but cells of neuronal origin may harbor C5a receptors (C5aR) as suggested by results of RT-PCR testing and that an apoptotic pathway is associated with the C5aR. To determine whether C5aR is expressed as an integral membrane protein, we generated mono- and polyclonal anti-CSaR antibodies. Flow cytometry showed a low-level expression of C5aR in TGW neuroblastoma cells. Epitope mapping suggested that a conformation change in C5aR occurs when exposed to C5a. Although an aphysiologically high concentration of C5a is necessary for inducing a transient increase in the intracellular Ca2+ level, TGW cells do employ the signal transduction pathway associated with C5aR, suggesting that these cells may serve as putative model for C5aR-expressing neurons.
