Stress, gut microbes and immune aging: a concise research news feature unpacking new study approaches and potential therapeutic implications.
Key Takeaways
- Chronic stress suppressed medial prefrontal cortex and periaqueductal gray activity in mice
- Stressed mice lost gut Lactobacillus reuteri and showed lowered spermidine levels
- Spermidine depletion accelerated hematopoietic stem cell aging and reduced lymphocyte production
