Summary
Inflammation of the central nervous system can have deleterious consequences. How the inflammatory cascade operates within the CNS is poorly understood. We have recently discovered a novel subset of immune cells, the perivascular macrophage, which regulates the recruitment of inflammatory cells. Aim of this proposal is to dissect the role of these cells during brain infections and autoimmune inflammation.
Mechanisms Of Alpha-hemolysin Induced Immunoevasion By Staphylococcus Aureus

Summary
S. aureus infections represent a serious global health problem. Currently, no vaccination is available demanding a better understanding of the immune response against this bacterium. We will test the hypothesis that S. aureus alpha-hemolysin represses the migration of innate immune cells to sites of cutaneous infection resulting in diminished immunity. Unraveling the mechanism behind this phenomenon will pave the way to better prophylactic and therapeutic measures against S. aureus infections.
Neutrophil Regulation Of Early Adaptive Immune Responses

Summary
The aim of this project is to utilise novel mouse models and imaging techniques to unravel the role of an immune cell called neutrophil in controlling immune responses. We show that as the first cell to leave the site of bacterial infection neutrophils can orchestrate subsequent activation of other immune cells. We plan to investigate the mechanisms and consequences of this process with a view to uncover new neutrophil-based therapeutic strategies that would improve the management of inflammator ....The aim of this project is to utilise novel mouse models and imaging techniques to unravel the role of an immune cell called neutrophil in controlling immune responses.

The Unique Nature Of Gamma Delta T Cell Recognition Resolved Through Interaction With H2-Q10

Summary
The liver is important for both digestion and immunity. Given these opposing functions, the liver must exert control points that prevent the immune system from recognising food products. We have now identified a new molecular target that controls the development of immune cells in the liver.
Immune Regulation Of Colitis And Associated Cancer

Summary
Inflammatory bowel disease is a debilitating condition that can significantly increase the likelihood of developing colon cancer. There are many different cellular pathways that lead to this inflammation, but we have uncovered a key signal that can prevent it from occurring. Specifically, we have identified how this signal increases a new type of suppressive cell that fights inflammation in the colon and can also stop this leading cancer.
Initial Interactions Of Herpes Simplex Virus With Innate Immune Cells In Human Skin

Funding Amount
$522,589.00
Summary
Herpes simplex viruses 1 and 2 cause widespread and occasionally serious diseases including genital herpes, neonatal death and encephalitis. Current vaccine candidates are at best partially effective. This grant will examine the way that the virus enters, initially spreads within the skin and interacts with immune cells to help determine which cells should be stimulated by vaccines.
