Understanding pain pathways
Our facilities & services
The Vetter group uses whole cell patch-clamp electrophysiology, automated electrophysiology, high-content and high-throughput imaging of dissociated sensory neurons as well as transiently or stably transfected mammalian cell lines to assess pharmacological effects on a range of ligand- and voltage-gated ion channels as well as G protein-coupled receptors. Her group routinely perform high-content screening and pharmacological characterisation of compounds from a range of sources and have established a state-of-the-art behavioural facility and single fiber extracellular recording setup at the University of Queensland for translational to preclinical models.
Research projects
To investigate the neuropharmacology of pain we use a range of techniques including: in vivo pain pathway characterisation, high-content imaging of cultured sensory neurons, high-throughput screening using calcium and membrane potential assays, and traditional pharmacological assays. While all pain has similar symptoms, it is becoming clear that the underlying mechanisms behind pain can vary.
By uncovering these new pain pathways, as well as identifying novel targets on peripheral sensory neurons, we aim to develop more effective pain therapies that treat the underlying cause of the pain, not just the symptoms.

Partnerships and collaborations
A/Prof Vetter works in collaboration with other leading Australian and international researchers and welcomes new collaborations. Together with leading peptide chemists, molecular biologists, electrophysiologists, clinicians, NMR and structural biology experts, the Vetter group seeks to unravel the molecular and structural basis of nociception.
Our past and present collaborators span a network of world-class researchers with complementary skill sets that further strengthen our capacity to conduct the highest quality research and produce outstanding research outcomes. Our collaborators are the best in the world in their respective fields, including mathematics, biophysics, membrane interactions, structure determination, modelling, transcriptomics, ion channel pharmacology, chemistry, pain management and ex vivo sensory recordings.
