Ion Channels

Ion Channels are proteins that regulate the electrical activity of cells. They are essential for electrical signal transduction, including cardiac contraction and neurotransmission.  Defects in ion channel function result in paroxysmal diseases like cardiac arrhythmias, epilepsy, and neuropathic pain.  Because of this, ion channels are very important drug targets.  At Michigan Pharmacology our research ranges from understanding the fundamental mechanisms of ion channel function to their disregulation in human disease.
