Molecular And Functional Characterisation Of Cell Surface Microdomains

Funding Amount
$4,803,731.00
Summary
This research program aims to gain a detailed understanding of the organisation of the cell surface at the molecular level. The cell surface is organised into domains with distinct functions. Visualisation of these domains, identifying their important components, and understanding how they form and function will have huge importance for therapeutic strategies aimed at combating the changes associated with cell transformation in cancer and in other human diseases such as muscular dystrophy.
This program brings together a team of researchers from The Walter and Eliza Hall Institute of Medical Research to study how the body regulates antibody production to fight disease. Antibodies are made by B-cells and are essential for a functional immune system. B cells circulate in the body, searching for signs of infection. When they encounter an invader, they mature, with the help of other immune cells, into antibody-producing cells. A small proportion of the cells are set aside as _memory� c ....This program brings together a team of researchers from The Walter and Eliza Hall Institute of Medical Research to study how the body regulates antibody production to fight disease. Antibodies are made by B-cells and are essential for a functional immune system. B cells circulate in the body, searching for signs of infection. When they encounter an invader, they mature, with the help of other immune cells, into antibody-producing cells. A small proportion of the cells are set aside as _memory� cells that can rapidly become antibodyproducing cells should the same infection occur again in the future. This is the basis of vaccination. This program aims to understand how a B cell changes into an antibody-producing cell, by studying the genes that are known to be required for the cells to form, or to do their work. We will study animals whose immune systems are under- or over-active, to find out what part of the antibody-producing process is faulty. Using this information, we hope eventually to be able to study diseases of antibody producing cells in humans (as occur in allergy, asthma, rheumatoid arthritis and leukaemia), to be able to identify the precise cause of the problem, and to suggest a therapy. This information may also be used to improve the outcome of vaccination where an enhanced antibody response is desired.Read moreRead less
Understanding G Protein-Coupled Receptors (GPCRs): Accelerating Discovery From Concept To Clinic.

Summary
G Protein-Coupled Receptors (GPCRs) form the largest family of receptors (and thus drug targets) in living organisms. Currently, the major reason that new drugs fail to reach the clinic is lack of appropriate drug effect (approx. 30%). Thus, we need a better understanding of how GPCRs work and how this relates to disease. Our Program addresses this knowledge gap, using GPCR models that are relevant to treatment of metabolic, cardiovascular and central nervous system disease.
Molecular Regulation Of Blood Cell Production And Function

Summary
The blood-forming system is an intricately controlled balance of cell proliferation, maturation and functional activity that is essential for oxygen transport throughout the body, blood clotting, and effective immune responses. Defining the genes and molecules that orchestrate blood cell production and function is crucial, not only for understanding the role of blood in health, but for establishing the bases of blood cell disorders such as autoimmunity and leukaemia, and for devising new clinica ....The blood-forming system is an intricately controlled balance of cell proliferation, maturation and functional activity that is essential for oxygen transport throughout the body, blood clotting, and effective immune responses. Defining the genes and molecules that orchestrate blood cell production and function is crucial, not only for understanding the role of blood in health, but for establishing the bases of blood cell disorders such as autoimmunity and leukaemia, and for devising new clinical strategies for fighting these lethal diseases. This program is conducted by a large, established team of investigators that have made world-class contributions to understanding blood cell formation and function for more than 30 years. Their work established the modern era of molecular haematology via discovery and analysis of blood cell hormones (colony-stimulating factors or CSFs), their receptors and intracellular mediators, which resulted in development of treatments for millions of cancer patients. The program is a multidisciplinary, team approach to fundamental biological questions with a focus on potential clinical and commercial outcomes involving collaborations with clinical medicine and the pharmaceutical industry. Research will focus on meshing novel genetic approaches in mice with translation studies in humans to identify new validated targets for therapeutic intervention in blood cell diseases, as well as building on the team s expertise in cytokine action with emphasis on the actions of the suppressor of cytokine signalling (SOCS) molecules, a key family of proteins that controls cytokine actions.Read moreRead less
