In establishing the left-right axis of the body in Drosophila, a torsion-like deformation of the cell occurs (cell chirality). Two myosin Is, Myo1D and Myo1C, are thought to be involved in this process, producing right-handed and left-handed cell chirality, respectively. A paper published in the May issue of this journal (Utsunomiya et al. (2024) Genes Cells 29: 380-396, DOI: 10.1111/gtc.13110) reported that when these myosin Is were expressed in macrophages to observe their interactions with the membrane at the single-molecule level, Myo1D exhibited mobility consistent with free diffusion, whereas Myo1C showed notably lower mobility. This picture, depicting two vortices in a strait, aptly illustrates their differences. Compared to the fast currents that produce the right-handed vortex in the back, the currents of the left-handed vortex in the foreground are docile.

A puffed-up fugu is wrestling with a toad. The body of the fugu has numerous spots that look like insulin secretory granules and a nucleus-like pattern, just like the pancreatic β-cells. Perhaps triggered by the wrestling, the fugu's body releases insulin. Inspired by a review article in this journal (Izumi (2023). Multiple pathways and independent functional pools in insulin granule exocytosis. Genes Cells 28: 471-481, DOI: 10.1111/gtc.13029).
