Comparing 2 hypotheses side-by-side
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.
Small molecule activators of Miro1 GTPase activity increase mitochondrial motility and facilitate intercellular transfer through enhanced organelle mobilization, targeting fundamental transport machinery.
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
