Human platelet spread on a fibrinogen surface and stained for S6K1 (green), Rac1 (blue), and actin (red). Immunofluorescence confocal microscopy reveals that S6K1 colocalizes with Rac1 and actin at the lamellipodial edge of spreading platelets. mTOR and its downstream effector S6K1 have long been known to orchestrate key cellular signaling systems. In this issue, Aslan et al show that platelet activation triggers S6K1 phosphorylation through mTOR in a signaling step before Rac1-mediated lamellipodial formation and demonstrate that mTOR and S6K1 have functional roles in platelet spreading, aggregation, and aggregate stability. See the article by Aslan et al on page 3129.
