Differential Contribution of L-, N-, and P/Q-type Calcium Channels to [Ca2+]i C...

Abstract We investigated the contribution of L-, N- and P/Q-type Ca2+ channels to the [Ca2+]i changes, evoked by kainate, in the cell bodies of hippocampal neurons, using a pharmacological approach and Ca2+ imaging. Selective Ca2+ channel blockers, namely nitrendipine, ?-Conotoxin GVIA (?-GVIA) and ?-Agatoxin IVA (?-AgaIVA) were used. The [Ca2+]i changes evoked by kainate presented a high variability, and were ...
