Cytoskeletal protrusions are emerging as key elements in the development of cellular networks through which material is readily exchanged. In parallel studies, Ortin-Martinez et al (2021) and Kalargyrou et al (2021) report for the first time a direct transfer of cytoplasmic and membrane-bound material between photoreceptors through nanotube-like connections, providing further evidence toward the existence of nanotube-mediated material transfer in vivo within the central nervous system.

眼对眼：光感受器采用类似纳米管的连接进行材料传输

细胞骨架突起正在成为细胞网络发展的关键要素，通过它可以很容易地交换材料。在平行研究中，Ortin-Martinez等人(2021) 和 Kalargyrou等人(2021) 首次报告了细胞质和膜结合物质通过纳米管状连接在光感受器之间的直接转移，为纳米管的存在提供了进一步的证据-介导的体内中枢神经系统内的物质转移。
