1Do astrocytes exist in discrete A1/A2 subtypes or along a continuous activation…
The skeptic challenged the fundamental A1/A2 binary model underlying multiple hypotheses, but this wasn't resolved. The answer critically determines whether sub…

2Is the metabolic shift from ketogenesis to glycolysis in astrocytes adaptive or…
The skeptic raised strong counter-evidence that lactate is neuroprotective, directly challenging the assumption that astrocyte glycolysis is harmful. This funda…

3What is the mechanistic coupling between astrocyte xCT cystine transport and GL…
The theorist proposed xCT-GLT1 coupling as a therapeutic target, but the skeptic noted this interaction lacks experimental validation. Understanding whether cys…

4What is the detailed molecular mechanism by which Mfsd2a transports lysophospha…
The abstract mentions a 'proposed transport mechanism' but indicates the mechanistic details remain unclear. Understanding the precise molecular mechanism is cr…

5What are the mechanistic pathways linking astrocyte xCT upregulation to GLT1 gl…
The hypotheses proposed xCT-GLT1 coupling in astrocytes but the debate identified this as poorly characterized. Understanding whether cystine/glutamate antiport…

6Can astrocyte-specific PFKFB3 inhibition selectively block complement productio…
The metabolic checkpoint hypothesis assumes glycolytic inhibition will preferentially target pathological complement production over essential astrocyte functio…

7What is the causal relationship between AQP4 mislocalization and tau strain-spe…
The debate presented correlative evidence but the Skeptic emphasized lack of causation data. Whether AQP4 disruption drives strain-specific spreading or results…

8What are the tissue-specific and disease-context variations in astrocyte reacti…
Multiple hypotheses assumed uniform mechanisms across the brain, but the skeptic noted that metabolic requirements and reactivity patterns vary dramatically bet…

9Do tunneling nanotubes exist and function for mitochondrial transfer in vivo un…
TNTs are central to multiple hypotheses but remain controversial due to culture artifacts and lack of in vivo validation. Advanced imaging in living brain tissu…

11Can astrocyte-microglial SPM transfer occur via gap junctions or exosomes in ne…
The astrocyte-microglial shuttle hypothesis assumes intercellular SPM transfer mechanisms that remain unproven. The debate identified this as a novel concept bu…

12Can complement-independent pruning pathways compensate for C1q inhibition?
The debate identified this as a potential mechanism that could undermine C1q-targeted therapies, but no data was provided on which alternative pathways exist or…
