The potential of human milk oligosaccharides in ameliorating traumatic brain injury-induced cognitive impairment in mice.
📄 Abstract
To investigate the ameliorative effect and underlying mechanisms of human milk oligosaccharides (HMOs) on cognitive impairment induced by traumatic brain injury (TBI) in mice. Forty-eight C57BL/6 mice were randomly divided into the sham-operated group, TBI group, and TBI+HMOs group. The TBI model was established via controlled cortical impact (CCI). Mice in the TBI+HMOs group received daily HMOs administration by gavage, while other groups were given normal saline. Relevant indicators were detected using behavioral tests, pathological staining, Western blot, and other methods. HMOs significantly improved cognitive function in TBI mice, inhibited hippocampal oxidative stress and the expression of proinflammatory cytokines (IL-1β, IL-6, TNF-α), alleviated intestinal barrier injury, and regulated the expression of synaptophysin, BDNF, and pro-BDNF. HMOs exert neuroprotective effects by targeting central inflammation, oxidative stress, synaptic function, and intestinal barrier integrity, providing a novel natural therapeutic candidate for TBI treatment.
