Summary
In Alzheimer’s disease, connections between neurons (synapses) are progressively damaged. The BACE inhibitor class of drugs entering Phase III clinical trials may slow the pace of neurodegeneration in patients with dementia. However, these drugs may simultaneously have negative effects on synapse function, learning and memory. This study will assess the effect of BACE inhibition on synapse properties and cognition and identify the contribution of key proteins affected by this treatment.
A Potential Analgesic Target In A Novel Clinically-relevant Neuropathic Pain Pathway.

Summary
Persistent pain arising from tissue damage, to nerves, muscles or joints for example, is devastating for patients and a huge social and economic burden. This work will investigate one of the pathways that goes awry after sensory nerves are damaged. These experiments will also test whether a drug being developed to treat Alzheimer's disease is effective at blocking the persistent nerve hypersensitivity that sometimes develops after injury.
Repurposing An Alzheimer’s Trial Drug To Block Relapse In Cocaine Addiction Models

Summary
Repeated exposure to drugs of abuse, such as cocaine, alters the reward circuitry of the brain. Enduring changes in the connections between neurons underlie addiction-related behavioural patterns, drug craving and the propensity for relapse after drug withdrawal. The pre-clinical research in this proposal aims to test whether blocking the function of a particular brain protein in mice can prevent relapse in two different paradigms that model cocaine addiction in humans.
Neuron To Glia Signalling: Learning How Synaptic Signalling Can Promote CNS Remyelination

Summary
An immature cell type in the brain, known as the oligodendrocytes progenitor cell (OPC), receives direct electrical communication from neurons. This communication regulates the behavior of the OPC, affecting its ability to divide and generate new brain cells. This project will identify the signaling molecules that guide the OPC to for this specialized contact with the nerve cell. Understanding this communication has important implications for the treatment of Multiple Sclerosis.
Investigating Secondary Effects Of BACE1 Inhibition, A Promising Therapy For Alzheimer's Disease

Summary
Synapses transfer information between neurons in the brain. In Alzheimer’s disease (AD), synapse loss results in dementia therefore it is imperative that any potential therapeutic drugs do not inadvertently cause further synapse loss. Drugs aimed at blocking production of toxic protein fragments in AD might have adverse secondary effects on synapse development and function. This research will determine whether this is the case and inform new therapeutic approaches aimed at minimizing side effect ....Synapses transfer information between neurons in the brain.
