he shape of cells controls the speed and duration of signaling and can maintain short-term signaling memory in cellular subdomains, report Craske et al. on page 1147. In response to stimulation, signaling molecules move through cells to newly available binding sites at a rate consistent with random diffusion. In round cells, such diffusible signals reach different regions of the membrane at nea...

Shape is an indicator of cell health. But how is the information in shape decoded? We hypothesize that decoding occurs by modulation of signaling through changes in plasma membrane curvature. Using analytical approaches and numerical simulations, we studied how elongation of cell shape affects plasma membrane signaling. Mathematical analyses reveal transient accumulation of activated receptors ...

The shape of the human erythrocyte is normally maintamed in vivo as a biconcave disc for 120 days. In vitro. the cell shape can be altered readily by amphipathic cornpounds; however. given time and an energy source. the cells can recover the discoid morphology. An active shape control mechanism is postulated to regulate erythrocyte shape. The shape recovery process is a necessary element in rev...
