Autophagy is important for pancreatic β-cell function, however, the role of mitophagy and mechanism for mitophagy in β-cells are unclear. Here the authors report that in stressed β-cells, lysosomal Ca2+ release promotes mitophagy via activation of the transcription factor EB (TFEB) and loss of β-cell TFEB aggravates glucose intolerance during high-fat diet.
