Abstract
1. Taurine has recently been known to protect against ischemia and heart failure. Taurine possesses plenty of actions on the ion channels and transports, but is very non-specific. 2. Taurine may directly and indirectly help to regulate the [Ca]i level by modulating the activity of the voltage-dependent Ca2+ channels (also dependent on [Ca]i/[Ca]o), by regulation of Na+ channels, and secondly via Na-Ca exchange and Na(+)-taurine cotransport. 3. Taurine can prevent the Ca2+ ([Ca]o or [Ca]i)-induced cardiac functions. 4. Therefore, it seems possible that taurine could exert the potent cardioprotective actions even under the condition of low [Ca]i levels as well as under the Ca2+ overload condition. 5. The electrophysiological actions of taurine on cardiomyocytes, smooth muscle cells, and neurons from recent studies are summarized.
