  • Title: Review of some actions of taurine on ion channels of cardiac muscle cells and others.
    Author: Satoh H, Sperelakis N.
    Journal: Gen Pharmacol; 1998 Apr; 30(4):451-63. PubMed ID: 9522160.
    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.
