Figure Lengend Snippet: a Flow cytometric analysis of anti-PD-L1-stained cells in tumor tissues after different treatments ( n = 5 independent mice). b Quantification of the percentage of PD-L1 positive cells in ( a ) ( n = 5 independent mice). c Schematic diagram of the mechanism of Sv@PM-M2p-mediated upregulation of PD-L1 within HCC TME. d Schematic illustration of the research procedure in bilateral subcutaneous HCC mouse model. e Representative bioluminescence images of bilateral subcutaneous HCC mice at specific time points with different treatments ( n = 5 independent mice). f Relative bioluminescence intensity curves for the various treatment groups ( n = 5 independent mice). g Flow cytometric analysis of anti-F4/80/CD206-stained macrophages and anti-F4/80/CD86-stained macrophages in tumor tissues after different treatments ( n = 5 independent mice). h Quantification of the percentage of F4/80 + CD206 + M2 TAMs and F4/80 + CD86 + M1 TAMs in ( g ) ( n = 5 independent mice). i Flow cytometric analysis of anti-CD44/CD62L-stained T cells (gated on CD3 + CD8 + T cells) in the spleens after different treatments ( n = 5 independent mice). j Quantification of the percentage of CD44 + CD62L - memory T cells in ( i ) ( n = 5 independent mice). k The assay of IFN-γ, TNF, IL-6, and IL-12 in serum after different treatments ( n = 5 independent mice). Unless specified otherwise, error bars represent the mean ± SEM. Statistical significance was determined by one-way ANOVA with Tukey’s test ( b , f , h , j , k ) and P -values were indicated.
