What if mitochondria have a buddy to supply them with the right substrates at the right time? Tune in this thursday, and our speaker @nunoraimundo.bsky.social will tell you how mitochondria-lysosome crosstalk can be a tool when metabolism needs to be rewired. See you there?

New preprint from our lab! We uncover how a subset of mitophagy proteins BNIP3 and NIX are repressed and protected from turnover, we think so that they can perform a surveillance role to detect mitochondrial dysfunction under basal conditions. t.co/4XKkd4LsFi
