Summary
The immune system consists of two arms - innate and adaptive. Current vaccine strategies rely mainly on adaptive features of the immune system to mediate immunity against pathogens. Many pathogens have evolved sophisticated strategies to manipulate the adaptive immune system to render it ineffective. This project will investigate microbial detection by the innate immune system, and aims to discover novel, more effective strategies to mediate immunity against intracellular pathogens.
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.
