Gut dysbiosis in Alzheimer's disease reduces butyrate-producing bacteria (Faecalibacterium prausnitzii, Roseburia intestinalis), causing systemic butyrate deficiency. Butyrate normally acts as an endogenous histone deacetylase (HDAC) inhibitor; decreased butyrate allows HDAC2 to suppress histone acetylation at promoters of anti-inflammatory genes in microglia, impairing their ability to phagocytose and clear amyloid-beta plaques. This HDAC2-mediated epigenetic silencing reduces expression of gen
Time-restricted feeding combined with circadian-synchronized probiotic delivery can restore disrupted sleep-wake cycles in AD patients by modulating gut microbiome circadian rhythms, which in turn regulate melatonin production and glymphatic clearance during sleep.
