Studying trisomic cell lines derived from RPE1 and HCT116 cells, Krivega et al find that autophagy is induced independently of mTORC1 in these cells. Rather, they observe that nuclear accumulation of TFEB and IRF3 and activation of the inflammatory response and autophagy in trisomic cells is dependent on the cGAS-STING pathway.
