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.

Summary
The aim of this proposal is to investigate immune cells called T follicular helper cells using a novel microscopy-based method that we have developed. This method lets us ‘tag’ these cells in a way that enables us to distinguish them from all other cells and follow them as they migrate to different immunological compartments during the response. T follicular helper cells are important for protective immune responses against pathogens and a better understanding of this T cell subset will aid vacc ....The aim of this proposal is to investigate immune cells called T follicular helper cells using a novel microscopy-based method that we have developed.

Summary
Protection from infections relies on different types of immune cells. While some of these cells are found in the blood, others reside in peripheral tissues such as the skin. We will analyse the function of these peripheral immune cells to understand how they work to fight off infections. We will also investigate how so-called memory cells that permanently reside in peripheral tissues can protect from re-infection with similar bacteria or viruses.
The Generation Of HSV-1 Specific Effector And Memory CD4+ T Cell Responses.

Summary
This proposal aims to determine the mechanisms underpinning the generation of helper T cell responses following HSV-1 infection. It will determine the factors that allow T cells to access sites of viral replication and the mechanisms by which they provide protection from skin infections.
Epigenetic Regulation Of CD8+ T Cell Function And Memory.

Summary
Upon virus infection, a subset of white blood cells, called killer T cells, are recruited to fight the infection. This proposal aims to examine molecular changes that occur within killer T cells and impart their specific function. We also aim to understand how killer T cells are _programmed� as they establish immunological memory. This proposal will provide insights important for the design and improvement of vaccine strategies to fight pathogens such as influenza, HIV and even tumors.
Role Of Dendritic Cell Subsets In The Generation Of CD4 T Cell Memory

Summary
This project studies the mechanisms responsible for establishing immunologic memory that is generated by vaccination and determines its efficacy. We aim to identify and study previously unacknowledged factors that critically affect the efficacy of vaccination. The results will be significant for both preventative and therapeutic vaccination (cancer, autoimmunity) and will help us to design new vaccines to improve immune function in infection, autoimmunity and cancer.
We have identified a population of immune cells called ‘resident memory T cells’ that reside in tissues of the body. These resident memory T cells play an important role in controlling infections, but it is also apparent that they can lead to aberrant immune reactions, causing autoimmune diseases. This project aims to further our understanding of these immune cells, including how they can be identified and generated, and how they can be controlled to prevent disease.

Summary
Recovery from infection, or vaccination, results in the establishment of protective immunity that persists for the life of an individual. Unfortunately, our understanding of how protective immunity is established and maintained after infection or vaccination is lacking. This proposal will determine whether specific enzymes involved in rewriting the genetic blueprint are key for establishing and maintaining this protective capacity. Understanding these mechanisms has implications for vaccination ....Recovery from infection, or vaccination, results in the establishment of protective immunity that persists for the life of an individual.

Subset Determination Of Tissue-Resident T Cell Memory

Summary
Immunity relies on white blood cells called T cells that circulate around the body and which are also found permanently lodged at body surfaces. It is non-circulating T cells that are the most important in protecting against infection. In this application we propose to show that only a subset of T cells can form the resident population and to identify the molecules that determine T cell residency. This information can then be used for the efficient construction of disease preventing vaccines.
