Viral Subversion of Autophagy
Based at Division of Virology, Addenbrooke’s Hospital
Supervised by Dr Rupert Beale (co-supervised by Dr Stephen Graham)
Autophagy is a process used by the cell to generate nutrients in times of starvation. Autophagosomes are generated by engulfment of cytoplasmic contents in a double-membrane vesicle which then fuses with a lysosome. This process has been adapted for cellular self-defence: invading microbes can be dragged into autophagosomes. While successful viruses must avoid autophagocytic destruction, they can also benefit from the increased resources autophagy provides. This project aims to elucidate the molecular mechanisms by which viruses such as HSV and influenza modulate autophagy by identifying and characterising viral proteins that bind to LC3, a key autophagy component.
