Analysis of metabolic markers in noncontrollers based on intermediate or high CMV infection risk showed an increased GLUT1 expression in CMV-specific CD8+ T cells of patients who are high risk for CMV, whereas no differences were detected in PKM, ATP5a, MTDR, and CPT1a (Supplemental Figure 3G). The gene discussed is SLC2A1; the disease is cytomegalovirus infection.
