Endothelin-1 and the Heart

  • Winifred G. Nayler

Abstract

The previous chapter (Chapter 13) described the effect of endothelin-1 on the coronary circulation, where the polypeptide evokes a small but transient dilator response followed by a dose-dependent, sustained and potent constriction. The constrictor response was described as being receptor mediated, and involving
  1. (i)

    an enhanced influx of Ca2+ ions through the Ca2+-selective channels, and

     
  2. (ii)

    a phosphoinositol-mediated mobilization of intracellular Ca2+.
