Nanotubes control blood distribution in the eye to help us see

Good blood redistribution in the eye is crucial for full functionality of the retina in adults. Now, researchers from the University of Montreal Hospital Research Centre (CRCHUM; Montreal, Canada) have discovered a new mechanism responsible for this redistribution using nanotubes. "For the first time, we have identified a communication structure between cells that is required to coordinate blood supply in the living retina," stated Adriana Di Polo, a neuroscience professor at Université de Montréal (Canada) and supervisor of the study. "We already knew that activated retinal areas receive more blood than non-activated ones," she explained, "but until now no one...
