Autophgy is a lysosomal recycling pathway for cytoplasmic material and organelles, which maintains cellular homeostasis. Eskelinen group investigates membrane dynamics during autophagy in mammalian cells. In order to clarify the elusive process of autophagosome formation, they have used three-dimensional electron microscopy to demonstrate connections between nascent autophagosomes and other membrane-bound organelles. The group has also studied the roles of small GTPases in autophagy, and reported that RAB24 plays a role in autolysosomes, the last intermediate on the autophagy pathway.
