Astrocytic Mitochondrial Transfer + Metabolic Copacking

Overview
This combination pairs astrocyte-mediated mitochondrial transfer enhancement with metabolic copacking strategies to deliver multi-component metabolic support to neurons[@astrocytemediated2019][@mitochondrial2020]. This addresses the fundamental energy crisis in neurodegenerative diseases by both increasing the supply (mitochondrial transfer) and improving the packaging/utilization of metabolic substrates.
Rationale
In Alzheimer's disease, neuronal hypometabolism precedes clinical symptoms by decades[@neuronal2018]. In Parkinson's disease, complex I deficiency drives alpha-synuclein aggregation[@complex2017]. This combination attacks both the symptom (energy failure) and the cause (impaired mitochondrial quality control).

Mitochondrial Transfer Enhancement
Astrocytes transfer healthy mitochondria to stressed neurons via tunneling nanotubes. Enhance this natural process with:
CX43 (Connexin-43) gap junction agonists: Promote gap junction formation for intercellular mitochondrial transfer
CD38 inhibitors: Boost NAD+ for improved mitochondrial dynamics
