Obesity may leave immune cells stuck in inflammatory mode after weight loss

A new EMBO Reports study suggests that obesity can leave a lasting epigenetic imprint on CD4 T cells, delaying the restoration of adaptive immune balance after weight loss. Using mouse models and human cohorts, researchers linked this immune “memory” to DNA methylation changes, saturated fatty acids, autophagy, and immune senescence.
