Comparing 2 hypotheses side-by-side
Engineering synthetic organelle export machinery combining elements from bacterial secretion systems with mammalian mitochondrial targeting sequences creates enhanced mitochondrial transfer capabilities.
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.
