LNP-CpG ODN-adjuvanted varicella-zoster virus glycoprotein E induced comparable levels of immunity with ShingrixTM in VZV-primed mice
文献摘要：
Latent varicella-zoster virus(VZV)may be reactivated to cause herpes zoster,which affects one in three people during their lifetime.The currently available subunit vaccine ShingrixTM is superior to the attenuated vaccine Zostavax? in terms of both safety and efficacy,but the supply of its key adjuvant component QS21 is limited.With ionizable lipid nanoparticles(LNPs)that were recently approved by the FDA for COVID-19 mRNA vaccines as carriers,and oligodeoxynucleotides containing CpG motifs(CpG ODNs)approved by the FDA for a subunit hepatitis B vaccine as immunostimulators,we developed a LNP vaccine encapsulating VZV-glycoprotein E(gE)and CpG ODN,and compared its immunogenicity with ShingrixTM in C57BL/6J mice.The results showed that the LNP vaccine induced comparable levels of gE-specific IgG antibodies to ShingrixrM as determined by enzyme-linked immunosorbent assay(ELISA).Most importantly,the LNP vaccine induced comparable levels of cell-mediated immunity(CMI)that plays decisive roles in the efficacy of zoster vaccines to Shingrix? in a VZV-primed mouse model that was adopted for preclinical studies of ShingrixrM.Number of IL-2 and IFN-y secreting splenocytes and proportion of T helper 1(Th1)cytokine-expressing CD4+T cells in LNP-CpG-adjuvanted VZV-gE vaccinated mice were similar to that of Shingrix? boosted mice.All of the components in this LNP vaccine can be artificially and economically synthesized in large quantities,indicating the potential of LNP-CpG-adjuvanted VZV-gE as a more cost-effective zoster vaccine.
