Rationalizing the use of functionalized poly-lactic-co-glycolic acid nanoparticles for dendritic cell-based targeted anticancer therapy

0

Background: Delivery of PLGA (poly [D, L-lactide-co-glycolide])-based biodegradable nanoparticles (NPs) to antigen presenting cells, particularly dendritic cells, has potential for cancer immunotherapy. Materials & methods: Using a PLGA NP vaccine construct CpG-NP-Tag (CpG-ODN-coated tumor antigen [Tag] encapsulating NP) prepared using solvent evaporation technique we tested the efficacy of ex vivo and in vivo use of this construct as a feasible platform for immune-based therapy. Results: CpG-NP-Tag NPs were avidly endocytosed and localized in the endosomal compartment of bone marrow-derived dendritic cells.
