While TNT-mediated mitochondrial transfer is identified as neuroprotective, the mechanisms governing which neurons receive mitochondria and how transfer efficiency is regulated remain unknown. This knowledge gap limits understanding of how to enhance this endogenous rescue pathway therapeutically. Gap type: unexplained_observation Source paper: Astrocytic LCN2 drives neuronal dysfunction in epilepsy by suppressing tunnel nanotube-mediated mitochondrial transfer via NLRP3 inflammasome activation.
