doi: 10.1016/j.isci.2022.103785
Figure Lengend Snippet: The IMC system analysis indicated PD-L1 + CD8 + T cells enrichment in lung tumor tissues and spatially located with PD-1 + effect T cells (A) Staining for tumor cells (Pan-CK), immune cells (CD45, CD3, CD4, and CD8), and nuclei (DNA) in one of the representative patients. (B) Normalized expression of CD45, Pan-CK, Epcam, CD3, CD4, and CD8 was shown in the viSNE plot. (C) The intensity of Pan-CK + , Epcam + , CD45 + , and CD3 + cells in lung tumors and adjacent tissues, N = 9. (D) Representative co-expression of CD8 and PD-L1 in tumor tissues from two patients. (E) viSNE plot of CD8 + T cells, showing the identification of 11 clusters. Each dot corresponds to a single cell, colored according to the cell cluster. (F) Heatmap of the Phenograph clusters of CD8 + cells. The relative expression levels of markers across cells were shown. (G) The frequency of PD-L1 + , PD-1 + , CD38 + , and CD39 + in CD8 + T cells in adjacent and tumor tissues is determined by IMC. N = 9, two tailed paired t-test. (H) Two representative samples of the neighborhood cells with PD-L1 + CD8 + T cells in lung tumor tissues. (I) viSNE plot showed the neighborhood cells with PD-L1 + CD8 + T cells in lung tumor tissues, including 7 clusters. (J) viSNE plot of the related markers of the CD8 + T cell clusters generated in (I). (K) Re-cluster of neighborhood CD8 + T cells with PD-L1 + CD8 + T cells in lung tumor tissues, including five clusters. (L) Heatmap of the related markers across the neighborhood CD8 + T cells generated in (K).
