英文摘要: |
Hydrogen sulfide (H2S), a newly discovered gaseous signal molecular alongside with nitric oxide (NO) and carbon
oxide (CO), is now recognized as a neurotransmitter and plays an important role in central nervous system. The production of endogenous
H2S from L-cysteine is catalysed primarily by two enzymes, cystathionine-β-synthase (CBS) or cystathionine-γ-lyase (CSE). H2S has
various physiological functions on central nervous system, not only can it act on it directly, but also exert significant effects indirectly
through anti-oxidation, modulating neuroendocrine and cerebral vascular function. Recently, evidences have been accumulated to
demonstrate that endogenous H2S has also been involved in the regulation of the pathogenesis of some nervous system disease, including
Alzheimer disease, febrile seizures, Parkinson's disease, cerebral stroke, ischemia-reperfusion injury and the brain damage of hereditary
disease. This article overviews the biochemistry and physiology of H2S, summarizes its role in central nervous disease and outlines the
potential options for the therapeutic exploitation of H2S. |
