Abstract:
:Reducing macrophage recruitment by silencing chemokine (C-C motif) receptor 2 (CCR2) expression is a promising therapeutic approach against atherosclerosis. However the transfection of macrophages with siRNA is often technically challenging. EGFP-EGF1-conjugated poly (lactic-co-glycolic acid) (PLGA) nanoparticles (ENPs) have a specific affinity to tissue factor (TF). In this study, the feasibility of ENPs as a carrier for target delivery of CCR2-shRNA to atherosclerotic cellular models of macrophages was investigated. Coumarin-6 loaded ENPs were synthesized using a double-emulsion method. Fluorescence microscopy and flow cytometry assay were taken to examine the uptake of Coumarin-6 loaded ENPs in the cellular model. Then a sequence of shRNA specific to CCR2 mRNA was constructed and encapsulated into ENPs. Target delivery of CCR2-shRNA to atherosclerotic cellular models of macrophages in vitro were evaluated. Results showed more uptake of ENPs by the cellular model than common PLGA nanoparticles. CCR2-shRNA loaded ENPs effectively silenced CCR2 gene in the atherosclerotic macrophages and exhibited a favorable cytotoxic profile to cultured cells. With their low cytotoxicity and efficient drug delivery, ENP could be a useful carrier for target delivery of CCR2-shRNA to inflammatory monocytes/macrophages for the therapy against atherosclerosis.
