Correlation between Exo-PD-L1 and sPDL1 profiles. a, b Quantitative analysis of Exo-PD-L1 levels (pg/ml serum) (a) and relative Exo-PD-L1 levels (pg/mg exosomal protein) (b) among healthy individuals (n = 27), stage I–II (n = 57) and III/IV (n = 28) NSCLC patients; *p < 0.05; ***p < 0.001; #p < 0.05; ##p < 0.01. c sPDL1 levels were not statistically different in NSCLC patients from healthy donors. d Correlation between Exo-PD-L1 and relative Exo-PD-L1 levels; Spearman’s correlation at r = 0.6, p < 0.0001. e Correlation between Exo-PD-L1 and sPD-L1 levels; Spearman’s correlation at r = 0.3, p = 0.0027
