Molecular interplay between ion channels and the regulation of apoptosis.

Apoptosis is the programmed and deliberate destruction of specific cells. This process occurs during normal development and maintains cellular homeostasis. Disruption or malfunction of apoptosis is implicated in diseases like cancer, AIDS as well as neurodegenerative disorders. The movement of monovalent ions appears to set the stage for the induction of the self-destruction machinery by creating an intracellular environment that favors activation and coordinated execution of the apoptotic program. Understanding the components and steps involved in this intricate process can further our insight to diseases and reveal new approaches for therapeutic treatment.
