Fluorescence-Activated Cell Sorting (FACS) revealed threefold higher numbers of PD-L1 positive platelets in NSCLC patients as compared to healthy donors (median pPD-L1 expression in healthy donors 0.29 (95%CI: 0.21 – 0.44), median pPD-L1 expression in NSCLC patients 0.89 (95%CI: 0.61–1.21) (Fig. 3 f). The gene discussed is CD274; the disease is non-small cell lung carcinoma.
