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.
## Mechanistic Overview Astroglial Gap Junction Coordination via Connexin-43 Phosphorylation Modulation starts from the claim that modulating GJA1 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## **Molecular Mechanism and Rationale** The connexin-43 (Cx43) protein, encoded by the GJA1 gene, forms the structural basis of gap junctions between astrocytes in the central nervous system, creating a highly interconnected glial
