Virus Like Particles Vaccine

Vlps is an ideal carrier for antigen delivery as it mimics the native virus hence can be readily recognized by the host immune system. Furthermore they contain no viral genetic material which makes them safer for vaccine recipients and operators that are in contact with the vaccine.

They resemble the actual structure of a virus which provokes a humoral and cellular immune response.

Virus like particles vaccine. This review presents data on commercial and experimental virus like particle vlp vaccines including description of vlp vaccines against influenza. A vaccine against hepatitis b virus has been produced which contains vlps in the lipid membrane envelope. Virus like particles vlps have been utilized as vaccine platforms to increase the immunogenicity of heterologous antigens.

Vlps mimic the native virus genetic material making them noninfectious and safe for use. Glaxosmithkline s engerix hepatitis b virus and. They are composed of one or more structural proteins that can be arranged in several layers and can also contain a lipid outer envelope.

It resembles a virus but doesn t contain the genetic material that would allow the vlp to. Hcmv is responsible for high morbidity and mortality in immunocompromised patients and remains the leading viral cause of congenital birth defects. Virus like particles vlps are self assembled viral protein complexes with sizes ranging 20 800 nm fig.

Virus like particles vlps are multiprotein structures that mimic the organization and conformation of authentic native viruses but lack the viral genome potentially yielding safer and cheaper vaccine candidates. Virus like particles are multimeric sometimes multiprotein nanostructures assembled from viral structural proteins and are devoid of any genetic material. Virus like particles a virus like particle or vlp is a structure assembled from viral proteins.

Virus like particles vlps are molecules that closely resemble viruses but are non infectious because they contain no viral genetic material they can be naturally occurring or synthesized through the individual expression of viral structural proteins which can then self assemble into the virus like structure. Virus like particles vlps are nanostructures that resemble the structures of viruses. Vlps trigger a high humoral and cellular immune response due to their repetitive structures.

The vaccine against coxsackievirus a6 contains vlps assembled from the virus capsid proteins produced in the baculovirus expression system. Virus like particles and nanoparticles for vaccine development against hcmv human cytomegalovirus hcmv infects more than 70 of the human population worldwide. Virus like particles represent a step forward in vaccine development.

A variety of diverse vlp types can serve as vaccine platforms and research has focused on engineering vlps to improve their efficacy as vaccines enhance their stability and allow for more versatile display of antigens. A handful of prophylactic vlp based vaccines is currently commercialized worldwide.
