Abstract

Hydrogen sulfide (H2 S) is one of three gasotransmitter molecules besides nitric oxide (NO) and carbon monoxide, which has emerged as an endogenous physiological regulator/modulator in the cardiovascular, nervous, immune and other systems in the body [1,2] , wherein the known toxicity of H2 S is tamed by the miniscule quantities produced. The enzymes that produce H 2 S from Lcysteine are cystathionine γ-lyase (CSE) and cystathionine [beta]-synthase (CBS) [1,3] . CSE predominates in the cardiovascular system and CSE-knockout mice develop hypertension and demonstrate reduced endothelium-dependent relaxation of resistance arteries, indicating a physiological role of H2 S in blood pressure (BP) regulation [4] . Various aspects of the pathophysiology of H2 S have been covered in other reviews in this issue. Before discussing research on H2 S and its role in the metabolic syndrome, we will briefly discuss the pathophysiology of the metabolic syndrome.
