📚 Hypothesis 1 Step 1/7
GluN2B-Mediated Thalamocortical Control of Glymphatic Tau Clearance

## Mechanistic Overview GluN2B-Mediated Thalamocortical Control of Glymphatic Tau Clearance rests on the claim that modulating GRIN2B can redirect glymphatic protein clearance through effects on thalamocortical oscillatory dynamics. GluN2B subunits (encoded by GRIN2B) form extrasynaptic NMDA recep...

📚 Hypothesis 2 Step 2/7
Closed-loop optogenetic targeting PV interneurons to restore theta-gamma coupling and prevent amyloid-induced synaptic dysfunction in AD

## Mechanistic Overview The therapeutic strategy centers on parvalbumin-positive (PV) fast-spiking interneurons within hippocampal CA1 stratum pyramidale and their critical role in maintaining oscillatory network dynamics. PV interneurons express exceptionally high densities of voltage-gated sodium...

📚 Hypothesis 3 Step 3/7
TREM2 Agonism to Redirect Microglia from Synaptic Pruning to OPTN-Deficient Neuron Protection

## Mechanistic Overview TREM2 Agonism to Redirect Microglia from Synaptic Pruning to OPTN-Deficient Neuron Protection starts from the claim that modulating TREM2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic O...

🗣️ Debate (resolved) Step 4/7
The debate framework mentioned multiple microglial subtypes but no analysis was provided on the molecular triggers, temporal dynamics, or reversibility of these state transitions. Understanding these mechanisms is critical for timing therapeutic interventions.

Consensus: TREM2 signaling enables protective microglial responses to amyloid pathology based on human genetics showing loss-of-function variants increase AD risk (OR ~2-4); Microglial state transitions are ther | Dissent: Whether TREM2→TYROBP→APOE axis represents a pathogenic driver of irreversible inflammation (Theorist

🗣️ Debate (in-progress) Step 5/7
Will single-cell and spatial atlases redefine disease by cell-state rather than organ or gene — making cell type the fundamental unit of medicine?
