Intercellular nanotubes (NTs) have been visualized in situ and in vivo throughout the nervous system, enabling direct, targeted transfer of cargo between selected cells.
- Why it matters: Existing models of neural communication emphasize synapses and extracellular signaling, leaving a structurally distinct, physically connected pathway insufficiently defined and validated in living tissue.
- What they did: The work synthesizes evidence that NTs form diverse connections—between neurons, microglia, astrocytes, pericytes, satellite glia, and peripheral sensory neurons—and can exchange mitochondria, proteins/aggregates, and calcium.
- The result: NT networks are dynamic and stress-responsive, supporting roles in homeostatic rescue, pathological propagation of toxic proteins in neurodegeneration, and non-synaptic calcium signaling, while motivating standardized definitions, rigorous quantification, and molecular manipulation tools.
