Nramp1 phagocyte intracellular metal withdrawal defense

Natural resistance-associated macrophage proteins (Nramp) are multispecific symporters facilitating proton-dependent import of divalent metals. Nramp1 restricts microbial access to essential micro-nutrients such as iron and manganese within professional phagosomes. Increased understanding of Nramp1 roles in human phagocytes will be useful for future therapeutic approaches against selected infectious and immune diseases.
