Acridine Orange/exosomes increase the delivery and the effectiveness of Acridine Orange in human melanoma cells: A new prototype for theranostics of tumors
2017
AbstractSpecifically
targeted drug deliverysystems with low immunogenicity and toxicity are deemed to increase efficacy of cancer chemotherapy.
Acridine Orange(AO) is an
acidophilicdye with a strong tumoricidal action following excitation with a light source at 466 nm. However, to date the clinical use of AO is limited by the potential side effects elicited by
systemic administration. The endogenous
nanocarrier
exosomeshave been recently introduced as a natural delivery system for therapeutic molecules. In this article, we show the outcome of the administration to human melanoma cells of AO charged
Exosomes(Exo-AO), in both monolayer and spheroid models. The results showed an extended drug delivery time of Exo-AO to melanoma cells as compared to the free AO, improving the cytotoxicity of AO. This study shows that Exo-AO have a great potential for a real exploitation as a new theranostic approach against tumors based on AO delivered through the
exosomes.
