title: Cellular magnesium transport in the vertebrate intestine.
abstract: Magnesium (Mg) absorption across the intestinal epithelium is crucial for Mg homeostasis in all vertebrates. Besides paracellular transport, it involves a cell-mediated component, and this predicts the presence of specific Mg carriers at both the apical and basolateral pole of the epithelial cells. Although the mechanism of transmembrane Mg transport in enterocytes, as in most cell types, has remained an elusive topic for many years, recent studies have provided promising new insights. We here recapitulate the progress that has been made in this field, and advance evidence for membrane carriers that are involved in transcellular Mg transport in the intestine.
