Summary
Lymphatic vessels are essential to maintain fluid balance in most tissues of the human body. Further the lymphatic vasculature plays a central role during cancer and contributes to tumour metastasis. Despite this integral function in health and disease little is known about the molecular programs that coordinate gene expression to build a functional vasculature. This research project will address this gap in our knowledge and will open up new therapeutic avenues for lymphatic vascular disorders
Nfi Genes Regulate The Switch Between Neurogenesis And Gliogenesis During Cortical Development

Summary
Cells within the brain fall into two categories; neurons or glia. Importantly, both derive from a common progenitor population, the radial glia, during development. Early in development radial glia produce neurons, while later they generate glia. The genes which control the switch from neuron production to glia production remain poorly defined. I propose to investigate how this switch is controlled in radial glia, focussing on a family of proteins known to regulate gene transcription.
Understanding ILC1 Transcriptional Regulation And Function In Immune Protection

Summary
Natural killer cells are innate cells that provide first line defense against infection and cancer. The recent discovery of a novel innate cell population has modified our vision of the early events necessary for immune protection. Understanding the role of these cells is critical as they could represent viable therapeutic targets. We have developed unique mouse models to experimentally target this population to determine how they are generated and their role in combating infection and cancer.
Lymphangiogenesis From Development To Disease: Analysis Of SOX18 Function In The Control Of Lymphatic Remodeling

Summary
Cancers are lethal mainly because they spread (metastasise) to other parts of the body via blood vessels and lymphatic ducts. Pilot studies suggest that suppressing the function of a gene, SOX18, reduces tumour metastasis. We now propose to confirm these findings and study this effect in detail, with the ultimate aim of developing new therapies able to complement already existing anti-cancer treatments.

Summary
Being born too early is the major cause of perinatal morbidity and mortality and accounts for the majority of neonatal deaths. The aim of this project is to gain a better understanding of the mechanisms involved in premature birth with a view to future development of clinically useful interventions to reduce the high rates of mortality and long-term disability.
Follicular Helper T Cell Development And Function: From Mechanisms To Application

Summary
Antibodies are the basis of most successful vaccinations. Diminished antibody responses lead to immunodeficiency while excessive antibody responses contribute to autoimmune diseases. We are studying a newly identified specialised helper T cell subset, termed follicular helper T cells, which is essential to regulate the high-affinity and long-lived antibody responses. The knowledge should provide new strategies to design better vaccines, to control infections, or to treat autoimmune disorders.
Nuclear architecture is critical to the preservation of genome integrity. The aim of this research proposal is to delineate the role of chromatin organisation in transcription factor target search and damage site recruitment of DNA repair factor machinery. To achieve this I have developed fluorescence microscopy methods to monitor changes in chromatin structure with submicron resolution. Only with this technology can I determine how chromatin dynamics maintain genome integrity or induce disease.
Nerve cell survival is dependent on both growth-promoting factors and factors released by neurotransmission, which can promote recovery in neurodegenerative conditions by overriding cell death pathways. The molecule responsible for activating death pathways in the nervous system is called p75. This project will investigate how p75 results in cell death, how synaptic signals can prevent the activation of the p75 death pathway and whether blocking p75 function can limit neurodegeneration.
