Research Themes

Cellular and Molecular Neuroscience

Clinical and Veterinary Neuroscience

Interests

Prion diseases, or transmissible spongiform encephalopathies, are infectious, fatal,

neurodegenerative conditions of humans and animal species including scrapie in sheep, bovine spongiform encephalopathy in cattle and Creutzfeldt-Jakob disease in humans.

Our current research focus is:

(a) prion strain analysis at the molecular and biochemical level

(b) determination of the sensitivity of ovine PrP transgenic Drosophila to ovine prion infectivity

(c) the use of ovine PrP transgenic Drosophila to strain type ovine prions

(d) the reduction and replacement of mammals in bioassays

We are interested in prion disease pathogenesis, transmission and therapeutic strategy including defining the nature of the infectious agent, determining the molecular basis of prion strain diversity, and understanding the conversion of PrPC into PrPSc,

An exciting new area of our research is the generation of an invertebrate model of mammalian prion disease utilising Drosophila transgenic for ovine PrP.
