Additionally, glutathione peroxidase 4 is reversibly induced by HCV to increase virion infectivity (Brault et al., 2016), and glutathione peroxidase activity could be an important prognostic factor in diabetic patients with Epstein-Barr virus infection (Dworzański et al., 2020) or as an adjuvant in the management of HIV-infected patients (Ogunro et al., 2006). The gene discussed is GPX4; the disease is Epstein-Barr virus infection.
