This research looks at the molecular pharmacology of G protein-coupled receptors (GPCRs), including those that have neuropeptide ligands. A major focus is the calcitonin gene-related peptide (CGRP) receptors, which are highly significant in the treatment of migraine.

CGRP is abundant in sensory neurons and may play a broader role in pain signalling, beyond migraine.

Projects

  • CGRP and related receptors – pharmacology and cellular signalling profiles in model cell systems, such as characterising new drugs as well as endogenous ligands.
  • Ability of peptides to activate and inhibit pain in animal models.
  • Determining where the peptides and receptors are expressed in pain-relevant locations in animal models and human tissues.
  • Collaborative human clinical studies on migraine provocation
  • Collaborative studies to develop novel animal models of receptor expression and behaviour
