Summary
T cell activation is often inefficient following infection or vaccination, resulting in poor control of pathogens. In this grant, we propose to investigate the cellular basis for sub-optimal CD4+ T cell activation following infection. Specifically, we will study the roles of antigen presenting cells in CD4+ T cell activation in an experimental model of visceral leishmaniasis caused by the human protozoan parasite Leishmania donovani.

Summary
Neisseria meningitidis causes meningococcal disease. It lives on the surface of the nasopharynx and in certain circumstances, can invade into the bloodstream causing sepsis. This is a complicated process, which involves many proteins produced by the bacteria. Many of these proteins contain a special covalent bond, the disulphide bond, which allows them to function properly. We are investigating how these disulphide bonds are put into proteins.
The development of better ways to prevent and treat influenza infection will be a major step forward in lessening the impact of the virus in communities worldwide. We have assembled a research team of seven groups who will determine the ways in which the effects of influenza can be mitigated through an understanding of the factors which lead to severe disease, and how these can be lessened by novel vaccination and treatment strategies.
