MetabolomicsFaecal microbiota transplant from aged donor mice affects spatial learning and memory via modulating hippocampal synaptic plasticity- and neurotransmission-related proteins in young recipients

BACKGROUND: The gut-brain axis and the intestinal microbiota are emerging as key players in health and disease. Shifts in intestinal microbiota composition affect a variety of systems, however, evidence of their direct impact on cognitive functions is still lacking. We tested whe...

MetabolomicsHuman umbilical cord-derived mesenchymal stem cells ameliorate perioperative neurocognitive disorder by inhibiting inflammatory responses and activating BDNF/TrkB/CREB signaling pathway in aged mice

BACKGROUND: Perioperative neurocognitive disorder (PND) is a key complication affecting older individuals after anesthesia and surgery. Failure to translate multiple pharmacological therapies for PND from preclinical studies to clinical settings has necessitated the exploration o...

MetabolomicsCD22 Blockade Alleviates Anesthesia Surgery-Mediated Cognitive Impairment in Aged Mice

Postoperative cognitive dysfunction (POCD) is a common complication characterized by cognitive decline following surgery, with neuroinflammation serving as a critical pathogenic mechanism. Emerging evidence indicates that CD22, an inhibitory receptor primarily expressed on B cells and microglia, ...

MetabolomicsWalnut protein hydrolysate alleviates neuroinflammation and memory impairment in naturally aged mice via a gut microbiota-metabolite-neuroinflammation axis
This study investigated age-associated alterations in the serum metabolome and the metabolic effects of walnut protein hydrolysate (WPH) supplementation in naturally aged mice. Male C57BL/6J mice at different ages (2-month, 10-month and 18-month) were used to characterize metabolic changes associate...

MetabolomicsVitamin D deficiency disrupts a host–microbiota bile acid axis in aged mice to drive Faecalibaculum rodentium expansion and intestinal epithelial barrier dysfunction
This study investigated how vitamin D deficiency alters the fecal metabolome and bile acid metabolism in mice and evaluated the contribution of Faecalibaculum rodentium bile salt hydrolase activity to intestinal epithelial barrier dysfunction. Two complementary mouse experiments were included. In th...

MetabolomicsPhotosynthetic bioenergetic-redox restoration rejuvenates the aged muscle regenerative niche

Aging impairs muscle regeneration, but the key constraint remains unclear. Aged injured muscle fails to restore mitochondrial respiration, membrane potential, ATP/NADPH balance and redox control, forming a bioenergetic-redox bottleneck. To target this, we engineered CM-NTU-Ce, a C2C12 membrane-co...
