Fibronectin, CD4, CD14, CD163, B7-H3, LAG3, Tim-3, PD-L1, VISTA, CD25, CD45RO, and CD44 were significantly highly expressed in ‘surrounding stromal leukocytes‘ regions, whereas the expression levels of GZMB, CD20, CD56, CD68, Ki-67, PD-1, FOXP3, and CD45 were higher in ‘immune-rich cancer cell islet’ regions. Here, GZMB is linked to cancer.
