Summary
The immune system protects us against infectious disease by killing invading microbes or pathogens. Macrophages are white blood cells that are important for the recognition and destruction of pathogens. This project aims to investigate the role of certain genes, which are turned on in macrophages when they sense invading pathogens, in protecting us against infectious diseases such as tuberculosis and gastroenteritis.
Enhancing Host Defence Against Intracellular Pathogens By Preventing INOS Interaction With A Negative Regulator, SSB-2

Summary
Secretion of nitric oxide (NO) gas by immune cells is a critical defence mechanism for the killing of intracellular pathogens. Production of NO within cells is regulated by the enzyme iNOS. We propose that preventing iNOS from interacting with its natural inhibitor protein (SSB-2) would allow enhanced and prolonged iNOS expression leading to increased NO and increased killing of pathogens such as the mycobacterium tuberculosis and the Leishmania parasite.
