Summary
I am a research scientist interested in the immune system. Specifically, I intend to investigate immunological memory, which is the basis of vaccination. This refers to the ability of certain immune cells such as T and B cells to ‘remember’ a pathogen, so that a rapid and enhanced response can be generated upon re-infection with the same pathogen. This can be investigated by experimental techniques such as flow cytometry, histology and confocal microscopy on cells from infected mouse tissue.
The Mechanisms Of SIV Entry Of Follicular Helper T Cells

Summary
Follicular helper T (Tfh) cells are a type of immune cells essential in antibody production. Preliminary data shows that SIV infects macaque Tfh cells. In this project, we will investigate the mechanisms by which SIV enters into Tfh cells, and test the susceptibility of human Tfh cells to HIV-1 infection ex vivo. This project will enable understanding of the fate of Tfh in HIV infection and its role in HIV host defense and it may facilitate the design of vaccine against HIV.
The Adaptive Immune Response To Epstein-Barr Virus.

Summary
Epstein-Barr virus (EBV), the causative agent of glandular fever, is carried by a large proportion of adults worldwide. EBV is known to cause many cancers including Burkitt's lymphoma and has been linked to autoimmune diseases such as multiple sclerosis. The aim of this project is to find new fragments of EBV that the body's immune system can recognise and use to protect itself against the virus. Once found these pieces will form parts of the puzzle that will one day combine as a vaccine against ....Epstein-Barr virus (EBV), the causative agent of glandular fever, is carried by a large proportion of adults worldwide.

Analysis Of Proinsulin-epitope Specific CD4+ T Cells In Blood Of People With Type 1 Diabetes

Summary
Type 1 diabetes (T1D) is an incurable autoimmune disease characterised by T-cell mediated destruction of insulin-secreting cells of the pancreas. Development of preventative therapies is hampered by paucity of knowledge regarding the targets of the autoimmune T-cell response. We have recently identified epitopes ‘seen’ by islet-infiltrating T-cells, located in proinsulin. Our aim is to examine proinsulin-specific T-cell responses in the peripheral blood of people with and without T1D.
The Role Of Signal Transducer And Activator Of Transcription- (STAT) Related Proteins In Dendritic Cells During Chronic Active Infections

Summary
Chronic infections produced by pathogens such as HIV, overwhelm our immune system leading to an exhausted state where cells responsible for the clearance of invading microorganisms are unable to respond effectively. We have recently identified a highly promising therapeutic target that enhances immune effector function. We seek to understand the underlying mechanism, and to explore its therapeutic potential for use as a common platform to treat diverse infections.
Dengue Host-cell Signalling Interactions: Novel Insights And Interventions

Summary
Dengue is a virus transmitted by mosquitoes that occurs in many tropical and subtropical regions. Approximately 40% of the world's population is at risk of this infection. Sometimes it can be mild but it can lead to severe illness and death especially with second infections. The body produces a response that over-reacts to the virus in these severe infections. The project aims to understand why the body does this and what parts of the immune system are affected using a model in mice.
Mechanisms Of T Cell Mediated Injury In Renal Vasculitis

Summary
Anti-MPO glomerulonephritis (GN) is an aggressive disease causing severe and permanent injury to kidneys. This disease is thought to be due to an immune-mediated response to a protein (MPO) in neutrophils (a type of white blood cell). There is some evidence that other immune cells, CD4+ T cells, may be important in this disease. Experiments using models of anti-MPO GN will aim to define the role and mechanisms by which CD4+ T cells cause inflammation in the kidney.
Investigating The Role Of Mucosal Associated Invariant T (MAIT) Cells In Mycobacterium Tuberculosis

Summary
Tuberculosis (TB) is a deadly infectious disease that kills 2 million people per year worldwide. If we are to eliminate this disease, we urgently need a new TB vaccine. I plan to look at what role a newly discovered type of T cell might play in TB infection and to see whether these cells can be manipulated by vaccination. This work will help us to understand more about the body’s first response to TB infection and how we can use this response in the design of new TB vaccines.
Antigen-specific Regulatory T Cells And HLA Associations In Autoimmune Renal Disease

Summary
Glomerulonephritis (GN), a common cause of kidney failure, usually results from an immune system attack on the kidneys. Current treatments suppress the whole immune system, making patients vulnerable to infection. We aim to harness the body’s protective immune cells (Tregs) as a potential GN treatment. Using mice genetically programmed to mimic a human GN, we will test if specifically targeted Tregs protect mice from disease. We will also test how they affect blood samples from humans with GN.
Determining The Mechanisms Of Tolerance After Autologous Stem Cell Transplantation For Multiple Sclerosis – The Role Of CD39+ T Regulatory Cells

Funding Amount

Summary
Autologous haematopoietic stem cell transplant offers relief for patients with aggressive forms of autoimmune diseases such as multiple sclerosis. Here, we aim to understand how this therapy relieves symptoms in multiple sclerosis patients by studying the biology of CD39+ T regulatory cells. Understanding these immune-suppressing cells can lead to the development of new transplant procedures without chemotherapy and ultimately improve transplant outcomes for autoimmune disease patients.
