Comparing 2 hypotheses side-by-side
Inhibition of alternative mitophagy pathways (BNIP3/NIX) in healthy donor cells prevents degradation of transferable mitochondria while maintaining quality control in recipient neurons.
Pharmacological enhancement of connexin-43 expression in astrocytes increases tunneling nanotube formation and mitochondrial transfer to damaged neurons, leveraging natural mitochondrial donation capacity for neuroprotection.
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
