SLC2A1 and neoplasm: In exploratory assays (n = 5), flow cytometry suggested GLUT1 enrichment in CD8+ terminally differentiated effector memory T cells re-expressing CD45RA (TEMRA), and GLUT1+ TIL fractions showed higher in vitro tumor cell killing compared with GLUT1− cells.<h4>Conclusion</h4>GLUT1 shows compartment- and context-dependent associations in the CRLM.
