Assay Method Information

Assay Name:  Inhibitors of T-Type Calcium Channels (SynthLib1)
Description:  Assay Provider: Xinmin Xie Assay Provider Affiliation: Bioscience Division, SRI International, Menlo Park, CA Grant Title: HTS Assay for Cav3 T-Type Channels using FLIPR Grant Number: NS050771-01 T-type Ca2+ channels are also called low voltage-activated channels because they open at voltages near the resting membrane potential of most cells. In many types of neurons, Ca2+ influx through T-type channels triggers low-threshold spikes, which in turn trigger a burst of action potentials mediated by Na+ channels (1). Burst firing is thought to play an important role in the synchronized activity of the thalamus observed in absence epilepsy, and also in a wider range of neurological disorders characterized by thalamocortical dysrhythmia (2). Prominent T-currents are also observed in dorsal root ganglion neurons, with subsets of nociceptors expressing more T-current than high voltage-activated Ca2+ currents (3). Considerable evidence supports the notion that a T-channel antagonist would
