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?

JCS cover: Annulate lamellae (AL) at endoplasmic reticulum (ER)–mitochondria contact sites (ERMCSs). Super-resolution image of HeLa cells showing Nup358-positive structures (green) and mitochondria (magenta). In addition to its localization at nuclear pore complexes (prominently concentrated around the nucleus at the centre of the cell), Nup358 is present in cytoplasmic AL, specialised ER subdomains enriched with a subset of nucleoporins. A fraction of these AL structures is closely associated with mitochondria, indicating their localization at ER–mitochondria contact sites (ERMCSs). Images were acquired using a Nikon Eclipse Ti2 microscope equipped with the CREST Optics DeepSIM X-Light super-resolution imaging module. Picture credit: Gowhith Kuppili. See article by L.
