1 Thus, our aim was to test whether endogenous H2S, which is produced by cystathionine-beta-synthase (CBS) in the CNS, acts specifically within the preBotC to modulate inspiratory activity under basal (in vitro/in vivo) and hypoxic conditions (in vivo). Hydrogen Sulfide cystathionine beta synthase Rattus norvegicus
2 Thus, our aim was to test whether endogenous H2S, which is produced by cystathionine-beta-synthase (CBS) in the CNS, acts specifically within the preBotC to modulate inspiratory activity under basal (in vitro/in vivo) and hypoxic conditions (in vivo). Hydrogen Sulfide cystathionine beta synthase Rattus norvegicus
3 Inhibition of endogenous H2S production by bath application of the CBS inhibitor, aminooxyacetic acid (AOAA, 0.1-1.0 mM) to rhythmic brainstem spinal cord (BSSC) and medullary slice preparations from newborn rats, or local application of AOAA into the preBotC (slices only) caused a dose-dependent decrease in burst frequency. Hydrogen Sulfide cystathionine beta synthase Rattus norvegicus
4 These data suggest that the preBotC inspiratory network receives tonic excitatory modulation from the CBS-H2S system, and that endogenous H2S attenuates the secondary hypoxic respiratory depression. Hydrogen Sulfide cystathionine beta synthase Rattus norvegicus
