BACKGROUND AND PURPOSE Hydrogen sulfide, a gasotransmitter, facilitates somatic pain signals via activation of Ca(v)3.2 T-type calcium channels in rats. Given evidence for the activation of transient receptor potential ankyrin-1 (TRPA1) channels by H(2)S, we asked whether TRPA1 channels, in addition to Ca(v)3.2 channels, contribute to the H(2)S-induced(More)
Given that high mobility group box 1 (HMGB1), a nuclear protein, once released to the extracellular space, promotes nociception, we asked if inactivation of HMGB1 prevents or reverses chemotherapy-induced painful neuropathy in rats and also examined possible involvement of Toll-like receptor 4 (TLR4) and the receptor for advanced glycation endproduct(More)
T-type Ca channels (T channels), particularly Cav3.2 among the 3 isoforms, play a role in neuropathic and visceral pain. We thus characterized the effects of RQ-00311651 (RQ), a novel T-channel blocker, in HEK293 cells transfected with human Cav3.1 or Cav3.2 by electrophysiological and fluorescent Ca signaling assays, and also evaluated the(More)
