Abstract

Stressed cells can exchange mitochondria through intercellular tunneling nanotubes. In this issue of the JCB, Glover et al. (https://doi.org/10.1083/jcb.202511211) describe two functionally different tunnels: one for exporting dysfunctional mitochondria and another for retrieving respiration-active healthy mitochondria.
