The invention describes novel PAR polypeptides and uses thereof. It relates in particular to PAR polypeptides lacking their functional endogenous activating peptide and capable of interacting constitutively with a ligand for a wild-type PAR. The invention also lies in methods of screening for active compounds, using modified PAR polypeptides, and also in the therapeutic use of identified compounds, in particular for the treatment of inflammation, of allergies, of diseases affecting the CNS, of neurodegeneration, or of psychiatric or cardiovascular diseases, and also in methods and compositions which can be used for this purpose. Other subjects of the invention include nucleic acids encoding a modified PAR, vectors and recombinant host cells and transgenic animals containing them, and also their uses in the context of a therapeutic, diagnostic or screening approach, for example. |
