Grx1 can also reduce low molecular weight disulfides and, thus, proteins with functionally important disulfide bonds could also be affected by Grx1 alterations.In contrast to damaging oxidations and measurements of GSH, PSSG and Grx have rarely been studied in lung diseases, and never in conjunction. In chronic obstructive pulmonary disease (COPD), Grx1-positive alveolar macrophages were negatively correlated with forced expiratory volume in 1 s (FEV1) and sputum Grx1 levels were higher during exacerbations [3]. In a murine model of allergic airway disease, we found increased Grx1 expression and activity [4].Given the importance of … ER -
