OxTalks will soon be transitioning to Oxford Events (full details are available on the Staff Gateway). A two-week publishing freeze is expected in early Hilary to allow all events to be migrated to the new platform. During this period, you will not be able to submit or edit events on OxTalks. The exact freeze dates will be confirmed as soon as possible.
If you have any questions, please contact halo@digital.ox.ac.uk
Mitochondria undergo stress induced hyperfusion to adapt their metabolic function and safeguard cellular survival during starvation.
The mechanisms that regulate the underlying cell-biological program are however largely unknown.
In this talk I am going to discuss how lipid transfer at contact sites between mitochondria and lipid droplets controls metabolic remodelling and promotes cell survival.
Specifically I will explain how the lipid transfer protein mitoguardin 2 couples these fundamental aspects of cell physiology.
