The prevalence of type 2 diabetes in increasing worldwide, the International Diabetes Federation predicting 435 million will have diabetes in 2030. The major driver of the diabetes epidemic is obesity. There is strong evidence linking type 2 diabetes and obesity to an increased risk of cancer. However, the exact mechanism promoting cancer development in obese and diabetic individuals is not clear. This project will examine the effects of high insulin levels on cancer development and progression.
Inflammatory skin disorders, such as psoriasis and dermatitis, are responsible for a large burden of human disease and affect people across alldemographics. Knockout (KO) of TNF signalling members in mice is known to induce skin inflammation. This project proposes to use these genetic mouse models to investigate how and why disruption of particular TNF superfamily members leads to disease and potentially identify new targets for treatment.

Summary
A common genetic variant results in absence of the fast muscle fibre protein ?-actinin-3 in more than one billion humans worldwide. Loss of ?-actinin-3 influences elite athletic performance, muscle bulk and strength in the general population, and disease severity in muscle wasting conditions. The goal of this study is to understand how ?-actinin-3 regulates muscle mass so that individuals at increased risk of muscle wasting may be identified and treated accordingly.
The Mechanism And Application Of A Superagonistic Antibody For Human IL-21.

Summary
Monoclonal antibodies are widely used in diagnosis and therapy due to their outstanding specificity and safety. The monoclonal antibodies recognizing cytokines with enhancing functions are an emerging class of novel reagents in immunotherapy. This project is to investigate how a newly indentified monoclonal antibody enhances the activity of a cytokine and use this immunostimulatory function to design new strategies for better vaccination and treatment for cancer and infection.
Host Cell Signalling During HTLV-1 Infection: Novel Insights And Interventions

Summary
Human T-leukemia virus 1 (HTLV-1) establishes a life-long infection and causes cancer and immune dysfunction. This study aims to find a cure for HTLV-1 by inducing the specific death of infected cells using novel therapeutic drugs that target host cell death pathways. Dead infected cells are then naturally cleared from the system along with the viral infection. The impact of HTLV-1 infection on tuberculosis severity will also be examined.
Signal Integration During The Early B Cell/CD4+ T Cell Interactions In T-dependent Antibody Responses

Summary
Effective humoral immunity results from the complex interaction of B and T lymphocytes. STAT3, CD40L, SAP and ICOS are molecules that are involved in this interaction. Genetic mutations of these molecules result in well defined primary immunodeficiencies underscoring their importance. This study aims to characterise the integration of these early signals as well as other inputs that B cells receive and characterise the CD4+ cells that provide this help.

Summary
Pituitary tumours encompass a number of pathologies. Their cause is not clearly established. Pituitary adenomas are one of the most frequent intracranial tumours. The genetics of sporadic tumours is unknown. Craniopharyngiomas are rare brain tumours arising in the pituitary stalk area that can have profound effects, presenting in childhood or later. To date there is limited knowledge on the cell signaling pathways causing these tumors, which can help to understand cancer in general.
Suppression Of Immunity By The Malaria Parasite Antigen Plasmodium Falciparum Erythrocyte Membrane Protein-1 (PfEMP-1)

Summary
The malaria parasite P. falciparum infects red blood cells and makes the cells put on their surface a protein called PfEMP-1. The parasite can effectively “hide” by constantly changing this protein and making it unrecognizable by the immune system. PfEMP-1 can also suppress the immune system so that it can’t respond adequately to infection. Therefore, understanding PfEMP-1 function is important. I will investigate how PfEMP-1 can do this by looking at its cross talk with the immune system.
