Discovery of the day
This study reveals that Myosin1D (Myo1D) and Myosin1C (Myo1C) direct clockwise and counterclockwise circumferential F-actin flows, respectively, in Drosophila macrophages, establishing a molecular basis for cellular chirality. The researchers demonstrated that Myo1D assembles F-actin into a circular arrangement with specific polarity and collaborates with Myosin2 to drive the directional rotation. This discovery advances the understanding of how cytoskeletal mechanisms orchestrate left–right asymmetric morphogenesis, a fundamental process that may inform your broader interests in how cellular and tissular disruptions, including those affecting fertility and aging, are programmed during development.
