“…The oxidation of H 2 S generates H 2 S n 2021222329, and the interaction of H 2 S with S-nitroso cysteine generates cysteine persulfide3031. Therefore, it is possible that the interaction of H 2 S with NO produces H 2 S n .…”

“…We recently found that polysulfides are produced by the oxida-391 tion of H 2 S in the brain Polysulfides with varying numbers of sulfurs are produced. 396 Polysulfides induce Ca 2+ influx in astrocytes, which is approxi-397 mately 300 times more potent than parental H 2 S (Kimura et al,398 2013; Nagai et al, 2004Nagai et al, , 2006Oosumi et al, 2010). The effect of 399 polysulfides is suppressed by TRPA1 selective inhibitors, HC-400 030031 and AP-18, as well as by siRNAs selective for TRPA1, sug- Fig.…”

“…In our previous research, we found that polysulfides activate TRP channels more potently than does H 2 S (Nagai et al 2006;Oosumi et al 2010). High concentrations of NaHS (1-10 mM) activate TRPA1 channels in sensory neurons in the urinary bladder and dorsal ganglion (Streng et al 2008;Ogawa et al 2012).…”
