Populærvitenskapelig sammendrag av avhandlingen/ Summary of the thesis

Autophagy is a cellular renovation process where our cells clean house to get rid of damaged or surplus components. Autophagy declines as we get old and when autophagy does not work properly, we risk developing diseases associated with ageing like Parkinson’s or Alzheimer’s disease and ALS. The delivery of cellular waste, which we call cargo, is mediated by proteins called autophagy receptors.

Our research group discovered the first autophagy receptor called p62. p62 exists in cells either as free floating filaments or as round, dense p62 bodies. p62 bodies act as a platform where p62 recruits selected cargos. p62 also orchestrates the construction of a membrane engulfing both p62 and the cargo.

In this study we used both human and mice cells that expressed different modified forms of p62 to study regulation and formation of p62 bodies. Microscopy and various biochemical methods were used to explore the role of three functional elements in p62 that determines the ability of p62 to form bodies and to get the waste degraded by autophagy.
