CD80 and neoplasm: Furthermore, the expression levels of co-stimulatory molecules, including CD80, CD86, and I-ab, were higher on tumor-infiltrating DCs from lent-miR-138-5p treated mice compared with other groups (Figure 3B and Supplementary Figure S2C), indicating enhanced maturity of tumor-infiltrating DCs from lent-miR-138-5p treated A549 bearing mice.
