Summary
Mortality in breast cancer rises to 80% in cases where secondary tumors form in other organs. To improve outcome, a better understanding of the processes involved in cancer spread is needed. Normal cells contribute to the growth and spread of a tumour and are a target for therapy. When a protein called caveolin-1 is lost from normal cells in a tumour, the prognosis for the patient is much worse. The aim of this project is to understand how this protein can regulate the spread of breast cancer.
The Role Of A New Class Of Chromatin Organising Hub

Summary
Within the cell nucleus, specific proteins weave DNA into structured loops that are vital for normal cell function. By studying the molecules involved, we have uncovered a ‘dock’ that controls this DNA architecture. We will define the components and function of this ‘dock’, and the resulting rapid cell death that occurs if it is disrupted. We will explore this cell death pathway thoroughly because we think it may help us to develop new cancer therapies.
The Role Of IL-17 In Regulating Liver Macrophage Permissiveness For Leishmania Infection

Summary
Visceral Leishmaniasis is a disease of poverty in the developing world caused by Leishmania parasites, which live and replicate within host tissue macrophages. A cytokine produced by host cells, IL-17A impairs the ability of liver macrophages to control this infection, as mice that lack IL-17A have lower parasite burdens in the liver after experimental infection. We propose to investigate if IL-17A mediates this impaired control by tuning the permissiveness of host macrophages to infection.

Summary
Each year over 250 million people contract malaria and over 1 million die. The key to the malaria parasite’s success is the ability to live inside host cells, including hepatocytes and erythrocytes. Here, we aim to determine how the malaria parasite lives within hepatocytes, to engineer mutant parasites that can no longer do so and to assess whether mutant parasites confer protection against future malaria. Our program will use the most virulent human parasite P. falciparum and the rodent parasi ....Each year over 250 million people contract malaria and over 1 million die.

Immunodominance And Protective Immunity In The Context Of A Complex Host-pathogen System.

Summary
In experimental infection models with simple organisms, pathogen-specific immune responses recognize only a small fraction of potential epitopes encoded by the genome. This phenomenon is termed immunodominance. We propose the first comprehensive study of immunodominance in humans in response to a complex pathogen, the Plasmodium parasite that causes malaria. This will provide valuable new knowledge of host-pathogen immunity and facilitate rational vaccine design.
