These data illustrate that glutaminolysis-mediated mitochondrial bioenergetics helped to sustain phospho-STAT3, a PD-L1 transcription factor, which finally led to generation of PD-L1+ ABC-DLBCL cells under Vγ9Vδ2 T lymphocyte stress. The gene discussed is STAT3; the disease is diffuse large B-cell lymphoma.
