The role of immuno-exosomes in innate immunity. This project aims to determine the role of exosomes (EV) in innate immunity. Exosomes are extracellular vesicles secreted by mammalian cells that have an important biological function in intercellular communication by transferring biologically active proteins, lipids, and RNAs to neighbouring or distant cells. Following exposure to a foreign organism, cells dynamically change the protein composition of the EV they secrete. While this data supports ....The role of immuno-exosomes in innate immunity. This project aims to determine the role of exosomes (EV) in innate immunity. Exosomes are extracellular vesicles secreted by mammalian cells that have an important biological function in intercellular communication by transferring biologically active proteins, lipids, and RNAs to neighbouring or distant cells. Following exposure to a foreign organism, cells dynamically change the protein composition of the EV they secrete. While this data supports a role for EV as key players in innate immunity, a full understanding of the biological relevance of these vesicles and how they serve as a cellular defence mechanism is lacking. This project will provide significant benefits such as addressing key questions in EV biology and providing new fundamental insights into a novel and poorly understood component of the innate immune response.Read moreRead less

Summary
Argonaute proteins and the mammalian antiviral response. Awarded the Nobel Prize for Medicine in 2006, RNA interference (RNAi) is a natural process that plants use to attack viruses. Humans possess all of the tools for RNAi, but whether it is used for antiviral defense is unknown. This project aims to uncover this immune process which will open new avenues to treat virus infections, from influenza to HIV.
The role of the innate immune response in the asymptomatic nature of viral infections in bats. Bats are natural reservoirs to a variety of viruses, including many that are lethal in humans and other mammals. This project will generate fundamental information on the mechanisms involved in the asymptomatic nature of viral infections in bats and contribute towards the development of new antiviral strategies for other susceptible species.
