| Abstract | Innate immunity plays an important role in host defense against microbial infections. It also participates in activation of acquired immunity through cytokine production and antigen presentation. Pattern recognition receptors such as Toll-like receptors and nucleotide oligomerization domain-like receptors sense invading pathogens and associated tissue injury, after which inflammatory mediators such as pro-inflammatory cytokines and nitric oxide are induced. Supersulfides are molecular species possessing catenated sulfur atoms such as persulfide and polysulfide moieties. They have recently been recognized as important regulators in cellular redox homeostasis by acting as potent antioxidants and nucleophiles. In addition, recent studies suggested that supersulfides are critically involved in the regulation of innate immune and inflammatory responses. In this review, we summarize current knowledge of the chemistry and biology of supersulfides, with particular attention to their roles in regulation of innate immune, and inflammatory responses. Studies with animal models of infection and inflammation demonstrated the potent anti-inflammatory functions of supersulfides such as blocking pro-inflammatory signaling cascades, reducing oxidative stresses, and inhibiting replication of microbial pathogens including severe acute respiratory syndrome coronavirus 2. Precise understanding of how supersulfides regulate innate immune responses is the necessary requirement for developing supersulfide-based diagnostic as well as therapeutic strategies against inflammatory disorders. |
