The role of thiols in antioxidant systems [PDF]
Free Radical Biology and Medicine, 2019 The sulfur biochemistry of the thiol group endows cysteines with a number of highly specialized and unique features that enable them to serve a variety of different functions in the cell. Typically highly conserved in proteins, cysteines are predominantly found in functionally or structurally crucial regions, where they act as stabilizing, catalytic ...

Microglia antioxidant systems and redox signalling [PDF]
British Journal of Pharmacology, 2016 For many years, microglia, the resident CNS macrophages, have been considered only in the context of pathology, but microglia are also glial cells with important physiological functions. Microglia‐derived oxidant production by NADPH oxidase (NOX2) is implicated in many CNS disorders.
