Summary
Innate lymphoid cells (ILCs) are specialized cells that defend the body against invading microorganisms at the body’s surfaces, mediate pathogen clearance and tissue repair but may also drive inflammatory conditions such as allergic asthma and inflammatory bowel disease. We will investigate the molecular switches that regulate this novel cell type and potentially uncover novel molecules or pathways for therapeutic targets.

Summary
The immune system can discriminate between invading microorganisms and the body's own tissues. Dendritic cells are specialised to alert the immune system in the case of infection. In this project we aim to understand how dendritic cells are generated and how they function to control the immune response. We will achieve this aim by using state of the art genomic technologies to describe the genetic programme of dendritic cells.

In this project we aim to understand how dendritic cells are generated and how they function to control the immune response. We will achieve this aim by using state of the art genomic technologies to describe the genetic programme of dendritic cells.

Summary
Cancer-induced immune suppression is a major obstacle to the effective treatment of many cancers. We have shown that the cytokine IL-23, plays an important role in cancer initiation, growth and development. My project aims to characterize the cells that produce IL-23 in the cancer microenvironment and define how it suppresses cells of the immune system. A greater understanding of this cytokine’s mechanism of action will enable the rational improvement of treatments for patients with cancer
Understanding The Role Of Innate Immune Cells In Regulating Gut-associated Lymphoid Tissues At Steady-state And In Disease

Summary
The intestine is the largest surface area forming a protective barrier between the external environment and the body. It represents the first line of defence against invading pathogens. The immune system of the intestine is critical to protect this tissue -any breakdown leads to profound and progressive inflammatory disease of the gut such as chronic inflammatory bowel disease. Our work will determine the critical the mechanisms that protect the gut opening the door to targeted intestinal immuno ....The intestine is the largest surface area forming a protective barrier between the external environment and the body.

Natural Treg are dependent on the transcription factor FOXP3, but the mechanism of action of FOXP3 is only now becoming defined for human Treg. Tregs are critical for a balanced, responsive immune system, and deviation from this balance results in autoimmune diseases or persistence of cancers. In order to intervene to treat these disease it is essential to first know what makes a normal Treg function, and to then compare this with the disease so that faulty genes can be targeted for intervention ....Natural Treg are dependent on the transcription factor FOXP3, but the mechanism of action of FOXP3 is only now becoming defined for human Treg.

Uncovering The Epigenetic Landscape That Regulates Human Transcriptional Memory

Funding Amount

Summary
The ‘T cells’ in our bodies develop a memory of previous infections so that we do not become ill from them again. However, we do not fully understand how this memory works and it fails as we get old. We will use cutting-edge techniques to examine the detailed molecular wiring that ‘remembers’ viruses and see how it changes over time. This is hoped to facilitate the design of new age-specific vaccines and drugs and promote a more personalised approach to preventing and treating immune diseases.
The Immune Modulatory Function Of Chondroitin Sulphate A In Placental Malaria: Protecting The Fetus, Promoting The Parasite?

Funding Amount

Summary
Pregnant women and their babies are susceptible to placental malaria infection. Malaria parasites infect the placenta by binding to chondroitin sulfate A (CSA). CSA levels increase in normal pregnancy. Studies suggest that CSA can suppress immune cell function. This study will look at the immune modulating function of CSA during pregnancy and placental malaria. CSA may act as camouflage, hiding the malaria parasite from immune cells. This may be a novel immune evasion pathway.
Extracellular Cues Compete With TCR Signalling To Alter Lymphocyte Polarity, Fate And Function.

Funding Amount
$509,954.00
Summary
Following an infection, our immune system generates a large and diverse repertoire of cells required to mount and regulate an appropriate immune response. The signals that control the different types of immune cells that develop, and how bacteria and viruses influence immune cell development, are not fully understood. This project will investigate the regulation of immune cell development, and how competing signals from infectious agents influence this process.
Understanding The Mechanisms Of Respiratory Viral Infection- And COPD-induced Predisposition To Secondary Bacterial Pneumonia
Funder

Funding Amount
$593,888.00
Summary
Bacterial pneumonia is a major health problem particularly for children and the elderly. Bacteria are resistant to antibiotics and new treatments are urgently required. Viral infection and emphysema lead to increased risk of pneumonia. We will investigate the mechanisms of how viral infections and emphysema lead to pneumonia. We will then use new treatments to stop these mechanisms from occurring to prevent and treat pneumonia. This project may produce new treatments and cures for pneumonia.
Dissecting In Vivo Cellular Responses To Interferons In Pathogen-infected Hosts

Summary
Tuberculosis (TB) is caused by virulent bacterium Mycobacterium tuberculosis and is a leading cause of death worldwide. Mechanisms underlying host resistance to the pathogen are poorly understood. Using a novel reporter mouse, the function of interferons in Mtb infection will be defined in vivo by tracking the cytokine-responsive cells. This will increase our understanding of the effects of these important cytokines in vivo, and could provide new candidate biomarkers for TB diagnosis.
