Comparing 2 hypotheses side-by-side
## Mechanistic Overview The hypothesis proposes that selective pharmacological modulation of pannexin-1 (Panx1) hemichannels could enable controlled intercellular transfer of mitochondria or mitochondrial components through gap junction-like conduits, thereby supporting metabolic cooperation between neurons and astrocytes in the neurodegenerative microenvironment. Under physiological conditions, Panx1 forms hexameric hemichannels at the plasma membrane that can open in response to elevated intr
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.
