Scientific Focus

This group is devoted to investigating the molecular mechanisms contributing to the development and maintenance of pain to identify and validate molecular targets for novel analgesics. We are using a multidisciplinary approach spanning molecular and cell biology, pharmacology, neuroanatomy, rodent behaviour, and experimental pain in humans.

The main current projects are focussing on:

  • Tetrahydrobiopterin as intrinsic regulator of pain hypersensitivity and persistence
  • Function of micoglial cells and neuroimmune interactions in neuropathic pain
  • Role of Inhibitor kappa B kinase beta in primary afferent and dorsal horn neurons (IKKbeta, gamma and alpha) for the development of neuropathic pain
  • Synaptic vesicle proteins as regulators of pain-evoked glutamate release and glutamate mediated excitotoxicity
  • Regulation of neuronal and glial cell responses, neuronal cell death and nerve regeneration after axonal injury by granulins

Methods

  • Rodent models for peripheral nerve injury and neuropathic pain, inflammatory and bone cancer pain, analysis of mechanical, heat and cold hyperalgesia and allodynia
  • Immunohistochemistry and in situ hybridization, immune-based protein/peptide analysis
  • Spinal cord microdialysis in rats and mice, analytical methods for various drugs, lipid- and other mediators, glutamate
  • Primary neuronal and glial cell cultures
  • Experimental pain models in humans including inflammatory and muscle pain
