Journal of Physiology, 596(16), 3675-3693. https://doi.org/10.1113/JP275067

Abnormalities of neurovascular interactions within the central nervous system of diabetic patients is associated with the onset of many neurological disease states. However, to date, the link between the neurovascular network within the spinal cord a...

Chronic pain can develop in response to conditions such as inflammatory arthritis. The central mechanisms underlying the development and maintenance of chronic pain in humans are not well elucidated although there is evidence for a role of microglia...

Alternative RNA splicing: contribution to pain and potential therapeutic strategy (2016)
Journal Article
Donaldson, L. F., & Beazley-Long, N. (in press). Alternative RNA splicing: contribution to pain and potential therapeutic strategy. Drug Discovery Today, https://doi.org/10.1016/j.drudis.2016.06.017

Since the sequencing of metazoan genomes began, it has become clear that the number of expressed proteins far exceeds the number of genes. It is now estimated that greater up to 98% of human genes give rise to multiple proteins through alternative pr...

Diabetic peripheral neuropathy affects up to half of diabetic patients. This neuronal damage leads to sensory disturbances, including allodynia and hyperalgesia. Many growth factors have been suggested as useful treatments for prevention of neurodege...
