Obesity May Leave a Biological Memory in Immune Cells Long After Weight Loss

A 10-year study published in EMBO Reports suggests obesity can leave durable DNA methylation marks on helper T cells, potentially sustaining risk for obesity-related disease years after body weight improves.

Key Takeaways

Researchers say helper T cells can retain obesity-linked DNA methylation marks for five to 10 years after weight loss.
The study links that immune memory to possible ongoing obesity-related risk.

Scientists Crack the Skin's Hidden Immune Alarm System

A Chinese research team has uncovered the signaling pathway through which keratinocytes in the skin's outer layer detect local damage and broadcast systemic immune alerts — resolving a long-standing mystery about how local threats become body-wide responses.

Key Takeaways

Chinese researchers mapped the complete signaling pathway by which skin keratinocytes convert local damage into body-wide immune alerts via cytokine release
The pathway is implicated in psoriasis, eczema, and contact dermatitis — conditions caused by excessive or misdirected keratinocyte alarm activation
