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

Summary
Melanoma is a significant cause of cancer-related deaths in Australians. Death is usually due to metastasis of the cancer to the lungs and other organs. In this project, we will take advantage of unique mouse models to determine whether inhibition of the function of a novel protein can prevent melanoma growth and metastasis to different organs. The results of this study may lead to new therapeutic approaches to control malignant melanoma and other metastatic cancers.
Studies On The Role Of The P101 Component Of The Class 1B PI 3-Kinase In Cell Migration And Activation.

Summary
This research will determine the biological role of a protein of unknown function that is likely to participate in movement of white blood cells through the body. The outcome of this research will increase our basic knowledge of how the immune system functions and could lead to alternate therapeutic strategies for the control of autoimmune diseases.
The glomerulus is the filtering component of the kidney. In many diseases, it can be the target of an inappropriate inflammatory response. As part of this response, white blood cells accumulate in the glomerulus where they cause damage. In this project, we make use of special microscopes to examine the glomerulus during an inflammatory response, with the aim of understanding the actions of leukocytes present in glomeruli and how they cause inflammation and damage the glomerulus.
Chemokine Mediated Collaboration Between T Cells And Dendritic Cells During Inflammation

Summary
The immune system protects us from foreign pathogens by using multiple immune cell types. Immune cells need to migrate and interact with each other in order to function properly. When immune cells fail to migrate appropriately, autoimmune diseases or immunodeficiency may develop. By understanding the molecules regulating their migration, we can promote or inhibit immune cell function.
Polarity Regulation In T Cells: Mechanisms And Consequences.

Summary
Advances in our understanding of how the immune system works have led to many breakthroughs in healthcare, including organ transplantation, management of autoimmune diseases and immunodeficiencies such as AIDS. To improve these treatments, we need a better understanding of how the immune system is controlled. This proposal explores the mechanisms by which immune cell signalling is regulated by spatial compartmentalisation within the cell.
Prof Carbone’s laboratory specialises in the study of immunity at the body surfaces. These surfaces include skin and mucosal tissues such as respiratory and gastrointestinal tract, all of which are the common points of entry for a variety of infectious agents. He has found that there exist cells at these peripheral sites that are separate from the immune components that one finds in the blood and, more importantly, that provide a profound level of protection during new infection.

He has found that there exist cells at these peripheral sites that are separate from the immune components that one finds in the blood and, more importantly, that provide a profound level of protection during new infection. He now propose to determine how best to induce this type of peripheral immune protection and how one can exploit these mechanisms for the purpose of infection control.Read moreRead less

Summary
T lymphocytes play an important role in the control of infection, but can also contribute to diseases such as autoimmune disease and cancer. This research will identify the function of a new subtype of T lymphocyte and determine whether inhibiting its function prevents disease.
