Serum sPD1 and sPDL1 as Biomarkers for Evaluating the Immune State of Lung Adenocarcinoma Patients

<div>LUAD patients showed immunosuppression and exhaustion of T cells compared with healthy controls. Gating of CD4<sup>+</sup>T/CD8<sup>+</sup>T cells ((a) and (b) and PD1 in CD8<sup>+</sup>T cells (c) from patients and healthy controls. Frequency of CD8<sup>+</sup>T cells (d) and CD4<sup>+</sup>T cells (e) of blood samples from patients and healthy controls. (f) Frequency of PD1<sup>+</sup>CD8<sup>+</sup>T cells of blood samples from patients and healthy controls. (g) The MFI of PD1 in CD8<sup>+</sup>T cells.
