RT Journal Article T1 Viral protein-based nanoparticles (part 2): Pharmaceutical applications A1 Mellid Carballal, Rocío A1 Gutiérrez Gutiérrez, Sara A1 Rivas, Carmen A1 García Fuentes, Marcos K1 Virus-like particles K1 Virosomes K1 Vaccines K1 Immunostimulation K1 Drug delivery K1 Diagnostics AB Viral protein nanoparticles (ViP NPs) such as virus-like particles and virosomes are structures halfway between viruses and synthetic nanoparticles. The biological nature of ViP NPs endows them with the biocompatibility, biodegradability, and functional properties that many synthetic nanoparticles lack. At the same time, the absence of a viral genome avoids the safety concerns of viruses. Such characteristics of ViP NPs offer a myriad of opportunities for theirapplication at several points across disease development: from prophylaxis to diagnosis and treatment. ViP NPs present remarkable immunostimulant properties, and thus the vaccination field has benefited the most from these platforms capable of overcoming the limitations of both traditional and subunit vaccines. This was reflected in the marketing authorization of several VLP- and virosome-based vaccines. Besides, ViP NPs inherit the ability of viruses to deliver their cargo to target cells. Because of that, ViP NPs are promising candidates as vectors for drug and gene delivery, and for diagnostic applications. In this review, we analyze the pharmaceutical applications of ViP NPs, describing the products that are commercially available or under clinical evaluation, but also the advances that scientists are making toward the implementation of ViP NPs in other areas of major pharmaceutical interest PB Elsevier SN 0928-0987 YR 2023 FD 2023-08-09 LK http://hdl.handle.net/10347/31218 UL http://hdl.handle.net/10347/31218 LA eng NO European Journal of Pharmaceutical Sciences 189 (2023) 106558 NO This publication is part of the following grants: PID2021–124986OB-I00 (Project “IMMMA”) funded by MCIN/AEI/ 10.13039/501100011033 and by “ERDF A way of making Europe”; AC21_2/00046 (Project “RAIN”) funded by Health Institute Carlos III/MCIN/AEI/ 10.13039/501100011033 and by “European Union NextGenerationEU/EURONANOMED 3; PID2021–126510NB-I00 funded by MCIN/AEI/10.13039/501100011033 and “ERDF A way of making Europe”; and ED431G 2019/02 grant funded by Xunta de Galicia.
