Ion Channels and Membrane Signaling Research Group

Closeup of membraneMembrane ion channels mediate neuronal action potentials and synaptic transmission and excitation-contraction coupling in muscle. Membrane transporters control ion flux and salt homeostasis in all cells. These proteins localize to plasma and intracellular organelle membranes, transducing environmental stimuli into intracellular signaling cascades, to regulate neuronal, cardiac, skeletal muscle, and neuroendocrine physiology. Faculty in the Department of Physiology are internationally recognized for their research into the fundamental molecular, biophysical, structural, and physiological aspects of membrane and intracellular signaling, underlying human health and disease. Labs within the department use a range of techniques from single molecule, electrophysiological, imaging, molecular, and transgenics to probe physiology and pathophysiology from stem cells, to organoids, to integrative animal models and gene therapy.
