Ion transport is the movement of ions across cell membranes or through channels within cells, tissues, or organs. This is a critical process in maintaining proper physiological functions such as nerve conduction, muscle contraction, and the regulation of pH and cell volume. Research in this area aims to understand the mechanisms, regulation, and implications of ion transport in various biological systems. This includes studying ion channels, pumps, and transporters, as well as their roles in health and disease conditions such as hypertension, cystic fibrosis, and neurological disorders. Approaches may include molecular biology, electrophysiology, imaging techniques, and computational modeling.
