SCREENING ASSAYS, MODULATORS AND MODULATION OF ACTIVATION OF RECEPTOR FOR ADVANCED GLYCATION END-PRODUCTS (RAGE)

摘要

A method of screening candidate agents for their ability to modulate RAGE activity where such RAGE activity is induced by an active co-located GPCR, the method comprising the steps of: contacting a RAGE polypeptide with a GPCR polypeptide in the presence of a candidate agent where the GPCR polypeptide is constitutively active and/or is activated by addition of an agonist, partial agonist or allosteric modulator of that GPCR; and detecting whether the candidate agent is a modulator of RAGE ligand-independent activation of RAGE by activated co-located GPCR by detecting an effect indicative of modulation of RAGE activation by the presence of the candidate agent and/or by detecting RAGE-dependent signalling that is modulated by the presence of the candidate agent.
