Stress Accelerates Immune Aging by Altering the Microbiome

Chronic psychological stress suppresses activity in the prefrontal cortex and periaqueductal gray, triggering a downstream depletion of gut Lactobacillus reuteri and its anti-aging metabolite spermidine. This biochemical crash directly accelerates the aging of hematopoietic stem cells in the bone marrow, mapping a novel brain-gut-bone axis for stress-induced immune decay.

Gut Signals Swap Sugar Cravings for Protein Selection

How does the gastrointestinal tract track a lack of protein and command the brain to swap food preferences? A new study reveals a dual-track gut-brain signaling axis triggered by protein deficiency.

This shows a brain and people of different ages walking on a path toward it.
