Hydrogen sulfide (H2S) is emerging as a physiological neuromodulator as well as a smooth muscle relaxant. We submit the first evidence that blood H2S levels are significantly lower in fasting blood obtained from type 2 diabetes patients compared with age-matched healthy subjects, and in streptozotocin-treated diabetic rats compared with control Sprague-Dawley rats. We further observed that supplementation with H2S or an endogenous precursor of H2S (L-cysteine) in culture medium prevents IL-8 and MCP-1 secretion in high-glucose-treated human U937 monocytes. These first observations led to the hypothesis that lower blood H2S levels may contribute to the vascular inflammation seen in diabetes. Antioxid. Redox Signal. 12, 1333-1338.
