In parallel, we performed multiplex immunofluorescent staining of CD3 (a marker of T cells), CD8, and granzyme B, finding a substantial enrichment of these three markers in pancreatic tumors from mifepristone-treated C57BL/6 mice (Fig. 4g–i), further confirming the increase in tumor infiltration by active CTLs. The gene discussed is GZMB; the disease is pancreatic neoplasm.
