JCS snapshot: A ULK1–MTFR1L feedback loop links mitochondrial fission, mitophagy and apoptosis

Posted by , on 22 July 2026

In our latest JCS snapshot we hear from Riccardo Babic, Leon Lucya and Christoph Reiter, who, together with Claudine Kraft and team, identified a ULK1–MTFR1L feedback loop that links mitochondrial fission, mitophagy and apoptosis.

Pearling and directed trafficking as determinants of mitochondrial genome organization and network architecture

Posted by , on 21 July 2026

In this highlight, we hear from Juan C. Landoni, who discusses his recent work uncovering how mitochondria distribute their genome through pearling (Landoni et al. 2026, Science), and the key role of mitochondrial trafficking in maintaining new material dissemination and network architecture (Winter, Landoni et al. 2026, JCB).

Our featured image, acquired by Manomay Pawar, depicts MDA-MB-231 triple negative breast cancer cells treated with drug Bemcentinib (R428), a small molecule inhibitor of AXL (a receptor tyrosine kinase) and labelled with phalloidin (actin;green), anti-Paxillin antibody to mark focal adhesions (magenta) and DAPI (DNA;yellow). The white coloured puncta represent colocalisation of paxillin with the ends

Living Architectures

Posted by , on 30 June 2026

To mark the 40th anniversary of the Musée d’Orsay, the CytoMorpho laboratory was invited to create a performance based on a series of experiments conducted for the occasion. The images produced for this show were real. There were no digital simulations or generative artificial intelligence. They were series of true photographs taken with microscopes.
