Comparing 2 hypotheses side-by-side
Light-activated ion channels in astrocytes trigger calcium influx that stimulates tunneling nanotube formation and mitochondrial export on demand, providing temporal and spatial control.
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.
