Corticosteroid binding globulin modulates circulating glucocorticoids, but its metabolic implications remain unclear. Here, the authors show that CBG regulators neutrophil elastase and alpha-1-antitrypsin control glucocorticoid bioavailability in adipose tissue, linking obesity and inflammation to metabolic outcomes in a sex-specific manner in mice and revealing parallels with human carriers of deleterious SERPINA1 mutations.
