TL;DR: A means by which individuals at highest risk of life-threatening COVID-19 can be identified is identified, and the hypothesis that neutralizing auto-Abs against type I IFNs may underlie critical CO VID-19 is tested.
Journal ArticleDOI
Enhanced Glutathione Levels and Oxidoresistance Mediated by Increased Glucose-6-phosphate Dehydrogenase Expression *
Francesca Salvemini,Annamaria Franzè,Angela Iervolino,Stefania Filosa,Salvatore Salzano,Matilde Valeria Ursini +5 more
TL;DR: This report suggests and provides the first direct evidence that G6PD induction serves to maintain and regenerate the intracellular GSH pool and observes that NF-κB activation, in response to tumor necrosis factor-α treatment, is strongly reduced in human HeLa cells overexpressing G6 PD.
Journal ArticleDOI
Mammalian small stress proteins protect against oxidative stress through their ability to increase glucose-6-phosphate dehydrogenase activity and by maintaining optimal cellular detoxifying machinery.
Xavier Préville,Francesca Salvemini,Stéphane Giraud,Sylvain Chaufour,Catherine Paul,Georges Stepien,Matilde Valeria Ursini,André-Patrick Arrigo +7 more
TL;DR: The results suggest that sHsp protect against oxidative stress through a G6PD-dependent ability to increase and uphold GSH in its reduced form and by using this redox modulator as an essential parameter of their in vivo chaperone activity against oxidized proteins.
Journal ArticleDOI
Enhanced expression of glucose-6-phosphate dehydrogenase in human cells sustaining oxidative stress
TL;DR: It is demonstrated that oxidative stress, caused by agents acting at different steps in the biochemical pathway controlling the intracellular redox status, determines the increase in G6PD-specific activity in human cell lines of different tissue origins.
Journal ArticleDOI
Ochratoxin A and zearalenone: a comparative study on genotoxic effects and cell death induced in bovine lymphocytes.
TL;DR: This report is the first to provide evidence of a statistically significant increase of structural CAs and of SCEs/cell associated with a reduction of the MI in all OTA- and ZEA-treated bovine lymphocyte cultures and a clear reproducible reducing effect of OTA on cell viability mediated by enhanced apoptosis.
