Hypertension is linked to a shortened erythrocyte lifespan, with endothelial cells acting as non-professional phagocytes to clear senescent erythrocytes. However, whether increased erythrophagocytosis contributes to endothelial inflammation remains unclear. Frataxin (FXN) plays a crucial role in controlling iron balance and metabolism. This study investigated the role of FXN-mediated iron engulfment in regulating endothelial pro-inflammatory phenotype.
