PLGA-PEI nanoparticle covered with poly(I:C) for personalised cancer immunotherapy.
Melanoma is the main cause of death among skin cancers and its incidence worldwide has been experiencing an appalling increase. However, traditional treatments lack effectiveness in advanced or metastatic patients. Immunotherapy, meanwhile, has been shown to be an effective treatment option, but the rate of cancers responding remains far from ideal. Here we have developed a personalized neoantigen peptide-based cancer vaccine by encapsulating patient derived melanoma neoantigens in polyethylenimine (PEI)-functionalised poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) and coating them with polyinosinic:polycytidylic acid (poly(I:C)). We found that PLGA NPs can be effectively modified to be coated with the immunoadjuvant poly(I:C), as well as to encapsulate neoantigens. In addition, we found that both dendritic cells (DCs) and lymphocytes were effectively stimulated. Moreover, the developed NP was found to have a better immune activation profile than NP without poly(I:C) or without antigen. Our results demonstrate that the developed vaccine has a high capacity to activate the immune system, efficiently maturing DCs to present the antigen of choice and promoting the activity of lymphocytes to exert their cytotoxic function. Therefore, the immune response generated is optimal and specific for the elimination of melanoma tumour cells.
期刊介绍:
The journal provides a unique forum for scientific publication of high-quality research that is exclusively focused on translational aspects of drug delivery. Rationally developed, effective delivery systems can potentially affect clinical outcome in different disease conditions.
Research focused on the following areas of translational drug delivery research will be considered for publication in the journal.
Designing and developing novel drug delivery systems, with a focus on their application to disease conditions;
Preclinical and clinical data related to drug delivery systems;
Drug distribution, pharmacokinetics, clearance, with drug delivery systems as compared to traditional dosing to demonstrate beneficial outcomes
Short-term and long-term biocompatibility of drug delivery systems, host response;
Biomaterials with growth factors for stem-cell differentiation in regenerative medicine and tissue engineering;
Image-guided drug therapy,
Nanomedicine;
Devices for drug delivery and drug/device combination products.
In addition to original full-length papers, communications, and reviews, the journal includes editorials, reports of future meetings, research highlights, and announcements pertaining to the activities of the Controlled Release Society.
