Investigating Different Forms of Hydrogen Sulfide in Cerebrospinal Fluid of Various Neurological Disorders.

ABSTRACT: Over the past 30 years a considerable amount of data has accumulated on the multifaceted role of hydrogen sulfide (H2S) in the central nervous system. Depending on its concentrations, H2S has opposite actions, ranging from neuromodulator to neurotoxic. Nowadays, accurate determination of H2S is still an important challenge to understand its biochemistry and functions. In this perspective, this study aims to explore H2S levels in cerebrospinal fluid (CSF), key biofluid for neurological studies, and to assess alleged correlations with neuroinflammatory and neurodegenerative mechanisms. A validated analytical determination combining selective electrochemical detection with ion chromatography was developed to measure free and bound sulfur forms of H2S. A first cohort of CSF samples (n = 134) w
