GLUT1 affects glycolysis within tumor microenvironment (TME) and promotes tumor progression. However, its specific mediated mechanism remains unclear in FL.<h4>Methods</h4>Baseline GLUT1 expression, infiltrations of M2 macrophage, and CD8+ T-cells were assessed by immunohistochemistry in FL with POD24 and long-term remission respectively. The spatial features of TME were assessed by MIBI-TOF and proteomics. Predictive immunophenotypes for POD24 occurrence was analyzed by random forest algorithm. The lactate production and the induction of M2 macrophages were detected when GLUT1 was transfected or knocked down in DOHH2.
