Role of T-Type Ca2+ Channels in Basal Insulin Release

Increases in plasma glucose concentration enhance the expression and activity of T-type Ca2+ channels in insulin-secreting pancreatic β-cells. The resulting elevation in T-type Ca2+ channel activity results in an elevation in the basal [Ca2+]i of β-cells.

Preface

It has been 30 years since the initial characterization of T-type channel current by Armstrong and Matteson (1985) and 15 years since the molecular cloning of the three subtypes of the T-type Ca2+ channel by Perez-Reyes et al., Cribbs et al., and Lee et al. (1998, 1999). In the last decade much has been learned regarding the biophysics, biochemistry, physiology, and pharmacology of these channels, with information being gleaned from a wide range of studies varying from structure– function relationships to therapeutic applications. In this book, recent advances in T-type Ca2+ channel research are rev
