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.
The Impact Of The Changes In Levels Of Adhesion Molecules NCAM2 And DsCAM On Synapse Formation And Function: Implications For Down Syndrome

Summary
Down syndrome (DS) results from triplication of chromosome 21 and leads to mental retardation, molecular mechanisms of which are not understood. We found that two proteins, NCAM2 and DSCAM, encoded at chromosome 21 are highly expressed in synapses. Synapses are specialized contacts between neurons which allow neurons to process information in the brain. In this project we will test a hypothesis that changes in NCAM2 and DSCAM expression result in synapse abnormalities observed in DS.
The primary aim of this grants to determine how HIV spreads through our immune system. The above knowledge will determine key Achille’s Heel moments in the HIV life cycle and thus lead to better therapeutic HIV treatments/prevention.
Specialised immune cells, called cytotoxic T cells, circulate through the body, and kill infected cells to protect us from disease. We discovered that a protein, DOCK8, is important for the regulation of T cell function. Importantly, humans with mutations in the DOCK8 gene suffer from a debilitating, and potentially lethal, immunodeficiency disease. This project will therefore elucidate the role of DOCK8 in immune cells, to better understand the consequences of DOCK8 deficiency for immunity.
The Role Of Co-signalling Receptors In Cytotoxic Lymphocyte Activity During Infection And Cancer

Summary
Cytotoxic lymphocytes (CLs) are immune cells that detect and kill cancer cells. CLs recognise ‘stress’ proteins on cancer cells through specialised receptors, and this provides the signal for them to kill. However, some cancer cells, such as leukemic cells, can interfere with this recognition to avoid killing by immune cells. This project will investigate the mechanism of recognition and killing of cancer cells by CLs, using both mouse models and cells from patients with acute myeloid leukemia.
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.

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.

Summary
Why do some people get allergies? Or serious infections? To investigate this we will study mice and humans with a mutation in the DOCK8 gene. People with mutations in the DOCK8 gene get Hyper-IgE Syndrome and develop severe viral infections of the skin as well as allergic disease. By investigating how DOCK8 works in the cells of the immune system, we hope to understand why these infections and allergies occur and find out why these problems can also happen in those without this specific genetic ....Why do some people get allergies?

Development Of Human Sensory Receptors Of The Inner Ear

Summary
Normal development of our special sense organs is crucial for sight, taste, hearing, and balance. The balance system mediates important postural and eye reflexes that are essential for movement and vision. Abnormal development of the balance system results in dizziness, vertigo, gait deficits, and impaired learning and reading ability in children. This study will investigate how the organs of balance mature and connect with nerve fibres of the inner ear during human development.
