Increasing populations are found to bear mild hepatic iron overload (HIO) due to unhealthy lifestyles, metabolic diseases, etc., whether this mild but chronic HIO induces hepatic inflammation is unknown. In the present study, mice receiving a 12-months 0.3% dextran-iron diet show mild HIO with no detectable oxidative damages in the liver but have infiltrated macrophages and increased IL-6, TNFα, AST and ALT since 6-months. The HNF4α/miR-122/CCL2 pathway, identified by our previous studies to induce macrophages infiltration, is initiated by chronic mild HIO...
