Human macrophage ferroportin biology and the basis for the ferroportin disease
Manuela Sabelli, Giuliana Montosi, Cinzia Garuti, Angela Caleffi, Stefania Oliveto, Stefano Biffo, Antonello Pietrangelo – 27 December 2016 – Ferroportin (FPN1) is the sole iron exporter in mammals, but its cell‐specific function and regulation are still elusive. This study examined FPN1 expression in human macrophages, the cells that are primarily responsible on a daily basis for plasma iron turnover and are central in the pathogenesis of ferroportin disease (FD), the disease attributed to lack‐of‐function FPN1 mutations.
