Imaging data and changes in immune memory T cell subsets in partial response (PR) patients before and after chemo-immunotherapy. (a, b) PET-CT fusion images and PET tomography data of a patient with PR after chemo-immunotherapy treatment showing good tumor control. (c) Comparison of peripheral CD4+ and CD8+ memory T cell subsets in PR patients pre- and post-treatment with chemo-immunotherapy. (d) Differential expression of PD-1 on CD4+ and CD8+ T cells in PR with chemo-immunotherapy. PET-CT: positron emission tomography-computed tomography. , , , , and ns, not significant.
