Turn up the lysosome

Lysosomes are digestive organelles of the endocytic and autophagic pathways. Increasing lysosome enzyme activities could help to clear pathological cellular waste. A recent study shows that lysosomal digestive functions can be promoted in isolated cells and mice by pharmacologically stimulating the autophagy- and lysosome-regulating transcription factors TFEB and ZKSCAN3 through previously unrecognized mTORC1-independent pathways acting via PKC.
