We aim to contribute to the molecular understanding of autophagy in health and disease. Autophagy is an evolutionarily conserved lysosomal degradation pathway that secures cellular homeostasis and that also contributes to a variety of age-related human diseases. Earlier we identified the human WIPI genes, that function as essential phospholipid effectors during the process of autophagy. Our recent findings revealed that human WIPI proteins act as scaffolds interconnecting energy- and nutrient-dependent signal control of autophagy.
Our current aims are to identify signaling networks that regulate WIPI proteins, and to identify synthetic and natural compounds that can modulate autophagy in pathophysiological circumstances such as cancer.
