The Embodied Trauma: How Childhood Adversity Rewires Brain-Immune Communication

A new study provides the first direct evidence that childhood maltreatment remodels the real-time communication loops connecting the immune system and the brain's fear learning circuits. The findings highlight how the timing and type of adversity (abuse vs neglect) fundamentally alter neuro-immune pathways through specific cytokine-mediated mechanisms that persist into adulthood.
