Specifically, we identified higher levels of CD3+ T cells, CD20+ B cells, NK1.1+ NK cells, CD11c+I-A/I-E+ APCs, CD68+ macrophages, and Gr-1+ neutrophils by immunofluorescent staining on tumor sections from mice post BNT162b2 intratumoral injection, which was consistent with the flow cytometry data (Fig. 2b–f). This evidence concerns the gene CD68 and neoplasm.
