Description
Hydrogen sulfide (H2S) is an endogenous gasotransmitter and is capable of regulating various endogenous signaling pathways, inculding inflamation and immune response. In mammals, H2S is mainly generated by two pyridoxal-5'-phosphate-dependent enzymes, termed cystathionine -synthase (CBS) and cystathionine -lyase (CSE). CBS-deficient mice showed autoimmune disorders. H2S play important roles in T cell development and differentiation, especially Treg cells development and differentiation.
