Oligodendroglia-to-neuron material transfer lights up the mouse CNS.

Intercellular material transfer in the central nervous system (CNS) supports neuronal survival and activity. Mayrhofer et al. (2023. J. Exp. Med.https://doi.org/10.1084/jem.20221632) characterize extensive regionally coordinated transfer of oligodendroglial ribosomal and nuclear material toward neurons, linked to satellite oligodendrocyte-neuron pairs in the mouse CNS.
