Summary
This research will begin to determine the significance of changes in the amount of recently-discovered proteins on the surface of cells called T lymphocytes. These cells control immune responses and move throughout the body to do this. Sometimes, they are activated inappropriately and cause diseases like asthma, arthritis and multiple sclerosis and other times they need assistance for activation (vaccination). It is therfore important to understand how the movement of these cells through the bod ....This research will begin to determine the significance of changes in the amount of recently-discovered proteins on the surface of cells called T lymphocytes. These cells control immune responses and move throughout the body to do this. Sometimes, they are activated inappropriately and cause diseases like asthma, arthritis and multiple sclerosis and other times they need assistance for activation (vaccination). It is therfore important to understand how the movement of these cells through the body is controlled. A better understanding of this process shuld allow us to design better ways to control it, thereby controlling the negative aspects of T lymphocyte activation.Read moreRead less
Targeting Neurovascular Communication As A Novel Way Of Reducing Vision Loss In Diabetes

Summary
Diabetes is a leading cause of blindness. Here, we evaluate whether diabetes causes changes in the way neurons signal to blood vessels, and whether blocking some of the signals from neurons reduces blood vessel abormalities. Overall, this information is critical to our understanding of the early changes that occur during diabetes and whether novel treatments used early in diabetes can prevent long term changes and vision loss.
Understanding The Mechanism And Significance Of CXCL16-mediated Protection Of Tumour Cells From CTL-induced Apoptosis.

Summary
This research will begin to determine the significance of changes in the amount of a recently-discovered protein on the surface of tumour cells. We have shown that an increase in expression of this protein protects tumour cells from destruction by our immune system's killer T cells. The outcome of this research could lead to a better understanding of how the immune system recognises and kills tumour cells, and ultimately, alternate vaccine strategies for tumours.
Studies On The Role Of The MIP-3beta/SLC System In The Priming Phase Of The Cytotoxic T Lymphocyte Response.

Summary
Generation of cytotoxic T cells (CTLs) is important for defence against viruses and cancer cells. However, when activated inappropriately, CTLs can contribute to diseases such as diabetes as well as transplant rejection. We intend to study the role of several recently-discovered proteins in this process. The outcome of this work may lead to the development of molecules that control CTL generation more specifically than existing therapeutics. Such inhibitors would potentially be useful in the tre ....Generation of cytotoxic T cells (CTLs) is important for defence against viruses and cancer cells.

Rapid HIV-1 Tropism Testing Using Novel, Soluble Mimics Of The HIV-1 Coreceptors CCR5 And CXCR4

Summary
This proposal seeks to develop an inexpensive assay to determine whether HIV patients will benefit from treatment with new drugs referred to as CCR5 antagonists. These are effective against HIV strains that use the CCR5 coreceptor, therefore a patient�s HIV coreceptor usage must be assessed before commencing therapy. Current assays are complicated, slow and expensive. Using novel, soluble mimics of the coreceptors we will develop an ELISA based test that can be operated using standard equipment.
