Update information. Based on behavioral paradigms, olfactory memory impaiment was considered as the first congnitive decline symptom in 5xFAD mice at 4-month-old. Proteomes in olfactory memory associated brain region, piriform cortex, at different stages were analyzed. The results indiciated that proteins alterations at different stages are diverse, but the core regulatory network involved in AD pathogenesis is conservd. Microglia and astrocyte specific proteins are enriched in the networks and associated with glial cell activation in the initial cognitive impairment stage. It implied the mutual effect of the two glial cells plays an essential role in Aβ induced initial AD pathogenesis.
