Study Reveals How Chronic Stress Accelerates Immune Aging Through Gut Microbiome Disruption
By
Neuroscience News
Summary
Researchers have demonstrated a definitive brain-gut-bone marrow axis in mice showing that chronic psychological stress suppresses key brain regions, disrupts the gut microbiome, and causes a severe drop in spermidine — an essential microbial compound. This spermidine depletion travels to the bone marrow and accelerates aging-like defects in hematopoietic stem cells, which are responsible for producing all blood and immune cells. The study provides a mechanistic link between stress, microbiome changes, and immune aging.

· 3 pulledChronic psychological stress suppresses key executive and emotional regions of the brain, disrupting the delicate ecosystem of the gut microbiome.
This intestinal crash causes a severe drop in an essential microbial compound called spermidine, which travels to the bone marrow and accelerates aging-like defects in hematopoietic stem cells.
The data reveals a definitive brain-gut-bone marrow axis in mice that explains this destructive link.
