Summary
Alzheimer’s disease (AD) is a complex disease where certain proteins congeal in the brain and metals accumulate. This project investigates the function of the proteins in microscopically transporting the metals. It will also look for tests that predict the onset of AD by measuring iron and iron related proteins by using special brain imaging (MRI), and measurements in spinal fluid. Finally, it will test drug candidates that target the metals, in animal models of AD, and in early clinical trials.
The blood system is made up of different types of blood cells (red cells, white cells, platelets etc). The correct number of each type of cell is controlled by chemical messengers called cytokines. Because overactive cytokine signalling can lead to inflammatory disease and leukemia it is tightly controlled by the other molecules in the body. This project aims to determine the exact mechanism whereby this is achieved with the aim of developing therapies to treat inflammatory disease and leukemia.
The Ghost In The Machine: Understanding How Haemostasis Is Regulated By Allosteric Disulphide Bonds

Summary
Genes encode proteins, which are the machinery of life. All life forms make proteins that contain bonds between pairs of cysteine amino acids called disulphide bonds. Prof Hogg has discovered a type of disulphide bond, the allosteric disulphide, which controls how proteins work by breaking or forming in a precise way. His research aim is to define how haemostasis is controlled by allosteric disulphides. Haemostasis gone wrong leads to heart attack and stroke.
Cellular Pathogenesis Of Neurodegenerative Disorders

Summary
Alzheimer's disease is the most common neurodegenerative disease of the ageing population and is associated with toxicity of the Abeta peptide. Prion diseases (eg CJD in humans) are infectious neurodegenerative disorders caused by misfolding of the prion protein. This proposal aims to bring together similar features of these diseases using novel cell and animal based studies to develop better diagnostics and greater understanding of the molecular basis of these disorders with a view to developin ....Alzheimer's disease is the most common neurodegenerative disease of the ageing population and is associated with toxicity of the Abeta peptide.

To Understand The Roles Of Plasminogen Activation In The Blood And The Brain

Funding Amount
$714,745.00
Summary
This research Fellowship will focus of the molecular and cellular biology of the plasminogen activating system, more commonly associated with the removal of blood clots. The research proposed will address a new paradigm for the removal of blood clots, and also a program to understand how the plasminogen activating system modulates the central nervous system and the immune response. This research will impact directly on ischaemic stroke, traumatic brain injury and multiple sclerosis.
Regulation And Mechanisms Of Cytotoxic Lymphocyte Function

Funding Amount

Summary
The immune system is the essential complex barrier that protects the organism for infections and some malignancies. Despite considerable efforts, the mechanism by which immune cells kill dangerous unwanted cells is poorly understood. This project will investigate the mechanism of action and the role in human pathologies of a key component of the immune system, a toxic protein perforin.
Mechanisms Of Gene Regulation - Structure, Function And Design

Summary
The human genome contains at least 20000 genes. The activity of these genes must be tightly controlled throughout an individual’s life and problems with the regulation of genes lie at the heart of many common and serious diseases, including most forms of cancer. My program of research is focused on understanding the mechanisms underlying gene regulation and on the design of new reagents that could be used to manipulate the activity of genes that behave aberrantly in disease states.
