Membrane Transport

membrane transport logo

Several gatekeeping processes regulate what crosses the biological membranes that form the borders of cells and intracellular organelles. Dr. Heiny's lab examines the role of Na,K-ATPase isoforms in skeletal muscle and has developed new technologies to measure ion and nutrient transport across membranes. Before Dr. Worrell's current focus on educating tomorrow's researchers and clinicians, he researched membrane transport in the gut. Dr. Mackenzie's research focuses on the membrane transport of metals such as iron, cobalt, and zinc. Research in membrane transport physiology serves to provide targets for pharmacological interventions that improve human health.
