Abstract

Mitochondria emerge as critical regulators of autophagy, a central homeostasis process and stress response, and induce or repress autophagy in a mitochondrial function and metabolism dependent manner. Our project analyses the role of mitochondria for autophagy regulation in a broad and unbiased approach by determining a mitochondria-centric genetic and metabolic interaction map of autophagy regulation. Additionally, we will dissect how mitochondria participate directly in the plastic and dynamic formation of autophagosomes.
