dc.description.abstract | In this study, dual drug-loaded nanoparticles were constructed to co-deliver low-dose doxorubicin (DOX) and miR-200c (DOX/miR-NPs) to inhibit programmed death-1 receptor (PD-L1) expression and trigger immunogenic cell death (ICD) in cancer cells. Two block copolymers, folic acid (FA)-conjugated PLGA-PEG (PLGA-PEG-FA) and PLGA-PEI, were formulated as folate-targeted NPs and loaded with DOX and miR-200c. The NPs, which were formed as nanosize objects (110.4 ± 2.1) with narrow size distribution (0.19 ± 0.02), effectively protected the miR-200c from degradation in serum. Modifying the NPs with FA increased not only their uptake by cancer cells in vitro but also their accumulation in tumor microenvironments in vivo, as compared with those properties of non-FA-modified NPs. The DOX/miR-NPs also exhibited efficacious inhibition of PD-L1 expression and robust induction of ICD in cancer cells in vitro and in vivo, resulting in increased dendritic cell maturation and CD8+ T cell response towards cancer cells. Furthermore, tumor growth was significantly inhibited by folate-targeted NPs loaded with the low-dose DOX/miR-200c combination, but not by treatments with free DOX, miR-NPs or DOX-NPs. Thus, our results suggest that simultaneous PD-L1 inhibition via microRNAs and the induction of an immunogenic tumor microenvironment via low-dose cytotoxic drugs may improve cancer therapy efficacy. | en_US |
