In the tumor tissues, we found that the activated state of TAMs in the tumors of mice bearing Lv-miR-96 Panc02 cells was predominantly M1-type, and the abundance of CD8+ cytotoxic T cells (CTLs) was also higher, compared with the tumors of mice bearing Lv-vector and miR-96-5p deficient cells. The gene discussed is CD8A; the disease is neoplasm.
