Transporting cells of ion-secreting epithelia are characterized by similar morphological patterns that include rich supplies of mitochondria, exotic patterns of surface amplification, and basolateral, plasma-membrane location of Na-K-ATPase, even though the direction of sodium transport across these epithelia is toward the apical side. Several new models for NaCl secretion propose that sodium, extruded into the intercellular space by Na-K-ATPase, reaches the apical side via the zonulae… CONTINUE READING
