ABSTRACT:
The present invention relates to antibodies which bind to C5aR and which are useful in diagnostic and therapeutic methods. The antibodies of the present invention are reactive with an extracellular loop of C5aR other than the N-terminal domain and are capable of substantially reducing or inhibiting the binding of C5ato C5aR and functional consequences of neutrophil chemoattractant receptor activation.
