HMOs support microbiota and immune development, but their effect on the preterm brain remains unstudied. Here, we examined the therapeutic potential of HMOs and short-chain galacto- and long-chain fructo-oligosaccharides (scGOS\/lcFOS) in a preclinical model for encephalopathy of prematurity. Pregnant Wistar rats were injected with 10 \u03bcg\/kg lipopolysaccharides at embryonic day 20, and pups were exposed to hypoxia (8% O<sub>2<\/sub>, 140 min) at postnatal day (P)4 (fetal inflammation and postnatal hypoxia; FIPH). From P1, FIPH-pups of both sexes were treated intragastrically with HMOs, scGOS\/lcFOS (9:1), or water. Transcriptomic analysis of CD11b\/c + microglia was performed at P6, while immunohistochemical, microbial and short-chain fatty acid (SCFA) analyses were performed at P20. Decreased cortical myelin in FIPH animals was rescued exclusively by HMOs. Furthermore, both HMOs and scGOS\/lcFOS treatments normalized reduced parvalbumin+ interneuron numbers in the hippocampus, potentially through promoting beneficial bacteria, including Lactobacillus and Bifidobacterium, and cecal acetic acid content. Interestingly, treatment with HMOs more effectively restored FIPH-induced upregulation of microglial genes associated with immune activation and normalized persistent activated microglial morphology in FIPH-males. HMOs supplementation holds promise to improve neurodevelopmental outcomes following preterm birth.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Neuropharmacology. 2025 Sep 15;276:110507.<\/p>\n","protected":false},"featured_media":0,"template":"","class_list":["post-8727","publication","type-publication","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.2 -
