Pre-plaque glutamatergic hyperexcitability, mitochondrial dysfunction, and dendritic remodeling in the hippocampus of one-month-old 5xFAD mice
A pre-plaque window in 5xFAD mice marked by GluN2B-linked glutamatergic hyperexcitability, early mitochondrial disruption, and selective dendritic and transcriptional vulnerability is defined, suggesting that synaptic and metabolic dysfunctions arise before substantial plaque deposition and may represent tractable earl...
