Novel Approach for Designing Rotavirus Vaccine Candidate Based on Two Plant Viruses

Abstract: Ротавирус А (род Rotavirus, сем. Reoviridae) остается основной причиной вирусного гастроэнтерита у детей в возрасте до пяти лет. Существующие аттенуированные вакцины имеют ряд серьезных недостатков, к которым можно отнести потенциальный риск реверсии к патогенной форме, а также побочные эффекты, из которых наиболее опасна инвагинация кишечника. Более того, эти вакцины оказались менее эффективны в развивающихся странах, где как раз фиксируется большая часть смертей, ассоциированных с ротавирусной инфекцией. Так… Show more

“…Immunofluorescence microscopy of compositions was performed as previously described ( Ryabchevskaya et al, 2020 ). SPs + 3AG compositions were treated with primary rabbit polyclonal Abs to the SARS-CoV spike protein (MBS432054) or rabbit polyclonal Abs to the SARS-CoV-2 spike protein (MBS434243) in a dilution of 1:50, and secondary Abs conjugated to Alexa Fluor ® 546 (Invitrogen™, ThermoFisher Scientific, United States) in a dilution of 1:500.…”

“…The problem of individual proteins’ low immunogenicity was solved by the application of a novel safe adjuvant, spherical particles (SPs), generated by thermally induced structural remodeling of the tobacco mosaic virus (TMV). Previously, we have published pioneering works on the characterization of SPs’ properties, including adjuvant activity and safety ( Atabekov et al, 2011 ; Nikitin et al, 2011 , 2013 , 2018b , 2018c ; Karpova et al, 2012 ; Trifonova et al, 2014 , 2015 ; Ksenofontov et al, 2019 ; Evtushenko et al, 2020 ) and several vaccine candidates against pathogens of a viral and bacterial nature have been developed ( Trifonova et al, 2017 ; Nikitin et al, 2018a ; Kurashova et al, 2020 ; Ryabchevskaya et al, 2020 , 2021 ). The authors assume that SPs in compositions with a target antigen act as a depot and this determines the adjuvant effect ( Trifonova et al, 2017 ).…”

“…The amino acid composition of the surface of SPs diff ers signifi cantly from that of TMV virions [31]. Avian infl uenza virus polyvalent epitopes of HA and M2 proteins [41] Rabies virus monovalent inactivated virion [42] Rotavirus monovalent epitope of VP6 protein [40] Puumala virus (hantavirus) monovalent inactivated virion [38] Coronavirus SARS-CoV-2 polyvalent RBD domain, conserved fragments of the S2 subunit [7] Bacillus anthracis bacterium monovalent protective antigen -PA [35] As a result of thermal rearrangement, TMV SPs acquire properties diff erent from those of virions. In particular, they have unique adsorption capabilities.…”
