Therapeutic and screening methods using C3a receptor and C3a

摘要

Human C3a Receptor polypeptides and DNA (RNA) encoding such C3a Receptor and a procedure for producing such polypeptides by recombinant techniques is disclosed. Also disclosed are methods for utilizing such C3a Receptor for the treatment of inflammatory and auto- immune disorders, among others. Antagonists against such C3a Receptor and their use as a therapeutic to treat inflammatory and auto-immune disorders, among others, are also disclosed. Also disclosed are diagnostic assays for detecting diseases related to mutations in the nucleic acid sequences and altered concentrations of the polypeptides. Also disclosed are diagnostic assays for detecting mutations in the polynucleotides encoding the C3a Receptor and for detecting altered levels of the polypeptide in a host.
