Comparing 2 hypotheses side-by-side
Genetically modified microglia overexpressing mitochondrial export machinery package healthy mitochondria into extracellular vesicles with neuron-specific targeting ligands.
## Mechanistic Overview TREM2-Dependent Astrocyte-Microglia Cross-talk in Neurodegeneration starts from the claim that modulating TREM2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## **Molecular Mechanism and Rationale** The TREM2 (Triggering Receptor Expressed on Myeloid cells 2) signaling cascade represents a critical node in neuroinflammation regulation, with its dysfunction fundamentally altering astrocyte-microgli
