Description
The abstract mentions that PV and SST interneurons differentially modulate neuronal activity and are implicated in AD, but doesn’t explain their distinct roles. This mechanistic gap limits targeted therapeutic approaches for restoring circuit balance.
Gap type: unexplained_observation Source paper: Regional interneuron transcriptional changes reveal pathologic markers of disease progression in a mouse model of Alzheimer’s disease. (None, None, PMID:37961679)
