Virus-like Particles for Disease Diagnosis and Drug Delivery Applications

Abstract: Virus-like particles (VLPs) are nanoscale, self-assembling cage structures made out of proteins with practical uses in biomedicine. They might be used to create better vaccinations, imaging equipment, gene and drug therapy delivery systems, and in vitro diagnostic equipment. VLPs are nanostructures that might be used in medicine, immunization, and diagnostics, among other areas. Many VLPs-based vaccines are now in use for the treatment of infectious diseases, and many more are on their way to clinical testing thanks to recent advancements in biomedical engineering. Although VLPs exhibit promising qualities in terms of efficacy, safety, and diversity, they may become more widely used in the future. Vaccines based on virus-like particles (VLPs) might serve as an effective addition to current immunization strategies for the prevention and treatment of emerging infectious diseases. The growing field of healthcare prevention has become increasingly interested in VLPs, leading to the discovery of various VLP-based candidate vaccines for vaccination towards a wide range of infectious pathogens, one of the most recent that has been developed is the vaccine against SARS-CoV-2, the effectiveness of that is now being tested. VLPs can elicit both antibody and cell-mediated immune responses, unlike standard inactivated viral vaccines. However, several problems persist with this surface display method and will need fixing in the future. VLPs-based medicinal delivery, nanoreactors for treatment, and imaging systems are being developed with promising results. The latest developments in the generation and fabrication of VLPs involve explorations of several expression systems for their creation and their application as vaccines for the avoidance of infectious diseases and malignancies. This manuscript offers the most advanced perspective on biomedical applications based on VLPs, as well as details innovative methods for manufacturing, functionalization, and delivery of VLPs.
