A mitochondria-lipid droplet stress pathway drives metabolic flexibility and cell survival

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.
