Abstract | SCOPE: METHODS AND RESULTS: Immunofluorescence staining and western blotting show that KD alleviates blood-brain barrier injury induced by hypoglycemia by increasing Podxl and zonula occludens-1 (ZO-1) levels. KD-fed mice show reduced brain edema by decreasing aquaporin-4 (AQP4) content and maintaining its polarized expression. 16S rRNA gene amplicon sequencing results show that KD reduces the Chao 1 index of gut microbiota α-diversity, and significant separation is detected in the β-diversity analysis between the control and KD-fed mice. KD increases the relative abundance of Firmicutes and Proteobacteria and decreases that of Bacteroidetes. Hypoglycemia can reduce SOD and GSH-PX levels while increasing TNF-α, IL-1β, and IL-6 mRNA levels in the brain tissues of mice. KD alleviates hypoglycemia-induced neuroinflammation by inhibiting microglia activation and TLR4/p38MAPK/NF-κB signaling pathway. Importantly, antibiotic cocktail depletion of the gut microbiota weakens anti-inflammatory and antioxidation responses in KD-fed mice. CONCLUSION:
