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.
Cigaratte Smoke Exposure Suppresses Alveolar Macrophage Responses To Lipopolysaccharide By Modifying The TLR4 Pathway

Summary
Long term cigarette smoke exposure is a major risk factor for cancer, heart disease and emphysema. A less known fact about smoke exposure is that it also leaves people susceptible to respiratory infections by i) physically damaging the lung lining and ii) suppressing cells responsible for coordinating the lungs defence system. This project will identify how smoke exposure blocks the early response to infection by the immune system and discovery novel ways of restoring normal lung defences.
Phagocytic Clearance And Immune Activation In Malaria

Summary
Macrophage white blood cells clear malaria infected cells by eating them, by three routes- by recognising ANTIBODIES or COMPLEMENT on the cell surface, or by the cell BINDING directly to the macrophage. Each has different results, such as amounts of cytokines produced. Cytokines clear malaria; in excess they can cause fatal immune pathology. We will investigate how variations in amount of antibody and complement and route of uptake of malaria infected cells might determine malaria outcome.
Studies On The Role Of The P101 Component Of The Class 1B PI 3-Kinase In Cell Migration And Activation.

Funding Amount
$457,267.00
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.
