Stability of the central nervous system and degenerative diseases of the retina (retinitis pigmentosa) and brain (dementia)

Lab head: Jonathan Stone
Location: Anderson Stuart N654

Our work analyses the cell biology of brain and retina, with an emphasis on the stability of the tissue, which breaks down in age-related diseases such as dementia, macular degneration and retinitis pigmentosa. Scientific work in rodent models is being expanded into clinical trials, which test neuroprotective agents - which increase stability

Research approach equipment: Our major techniques analyse the neuropathology of brain or retina, in models of dementia and retinal degeneration. This approach is complemented with functional tests, of the electroretinogram and of behaviour.
