Analysis of a chitinase from EpapGV, a fast killing betabaculovirus
(Springer, 2014-04)The main function of baculoviral chitinase protein (V-CHIA) is to promote the final liquefaction of infected host larvae, facilitating the dispersion of occlusion bodies (OBs) in the environment. In this study, a v-chiA ... -
Baculovirus AcMNPV induces type I interferons and NK/NKT cells-mediated protection against foot-and-mouth disease virus in mice
(Elsevier, 2020-08)Foot-and-mouth disease is a viral illness that affects cloven-hoofed animals causing serious economic losses. Inactivated vaccines against its causative agent, foot-and-mouth disease virus (FMDV), require approximately ... -
Baculovirus capsid display in vaccination schemes: effect of a previous immunity against the vector on the cytotoxic response to delivered antigens
(Springer, 2018-12)The baculovirus Autographa californica multiple nuclear polyhedrosis virus (AcMNPV) infects lepidopteran invertebrates as natural hosts, although it also has been used as display vector for vaccine development. In this ... -
Baculovirus Insecticides in Latin America: Historical Overview, Current Status and Future Perspectives
(2015)Baculoviruses are known to regulate many insect populations in nature. Their host-specificity is very high, usually restricted to a single or a few closely related insect species. They are amongst the safest pesticides, ... -
Baculovirus transduction in mammalian cells is affected by the production of type I and III interferons, which is mediated mainly by the cGAS-STING pathway
(American Society for Microbiology, 2020-11)The baculovirus Autographa californica multiple nucleopolyhedrovirus is an insect virus with a circular double-stranded DNA genome, which, among other multiple biotechnological applications, is used as an expression vector ... -
Baculovirus vectors induce the production of interferons in swine : their potential in the development of antiviral strategies
(MDPI, 2021-11)The huge variety of viruses affecting swine represents a global threat. Since vaccines against highly contagious viruses last several days to induce protective immune responses, antiviral strategies for rapid control of ... -
Biotechnological applications of occlusion bodies of Baculoviruses
(Springer, 2018-08)The ability of Baculoviruses to hyper-express very late genes as polyhedrin, the major component of occlusion bodies (OBs) or polyhedra, has allowed the evolution of a system of great utility for biotechnology. The main ... -
Co-inoculation of baculovirus and FMDV vaccine in mice, elicits very early protection against foot and mouth disease virus without interfering with long lasting immunity
(Elsevier, 2013-05-31)Baculoviruses (Bvs) potentiate the immune response against soluble antigens. We investigated whether Bv could be used as immunoactivator in foot-and-mouth disease (FMD) vaccines using the BALB/c mouse model. Mice were ... -
Comparison of strategies for the production of FMDV empty capsids using the Baculovirus Vector System
(Springer, 2014-11)Recombinant FMDV empty capsids have been produced in insect cells and larvae using the baculovirus expression system, although protein yield and efficiency of capsid assembly have been highly variable. In this work, two ... -
Double-layered rotavirus-like particles are efficient carriers to elicit strong CTL responses to delivered heterologous antigens
(Elsevier, 2014-11)The first 92 amino acids of VP2 of rotavirus are dispensable for VLP assembly and can be replaced by heterologous reporter proteins without affecting either self-assembly of chimeric VP2 or the interaction with VP6 to ... -
Effects of deletion of the ac109 gene of Autographa californica nucleopolyhedrovirus on interactions with mammalian cells
(2017-03)Baculoviruses are able to enter into mammalian cells, where they can express a transgene that is placed under an appropriate promoter, without producing infectious progeny. ORF109 encodes an essential baculovirus protein ... -
Effects of Mixed Baculovirus Infections in Biological Control: A Comprehensive Historical and Technical Analysis
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-08-30)Baculoviruses are insect-specific DNA viruses that have been exploited as bioinsecticides for the control of agricultural and forest pests around the world. Mixed infections with two different baculoviruses have been found ... -
First report of Chrysodeixis includens nucleopolyhedrovirus (ChinNPV) infecting Chrysodeixis includens (Lepidoptera: Noctuidae) in Argentina
(2018-09)Typical baculovirus infection symptoms were observed in Chrysodeixis includens Walker (Lepidoptera: Noctuidae) larvae from a laboratory rearing in Tucumán, Argentina. Scanning electron microscopy revealed the occurrence ... -
Functional analysis of Spodoptera frugiperda nucleopolyhedrovirus late expression factors in Sf9 cells
(2013-02)We used transient expression assays to assess the function of the baculovirus Spodoptera frugiperda M nucleopolyhedrovirus (SfMNPV) homologs of Autographa californica MNPV (AcMNPV) factors involved in late gene expression ... -
Genetic variants in Argentinean isolates of Spodoptera frugiperda Multiple Nucleopolyhedrovirus
(Springer, 2020)The fall armyworm, Spodoptera frugiperda (JE Smith) is a key pest in the Americas. Control strategies are mainly carried out by use of chemical insecticides and transgenic crops expressing Bacillus thuringiensis toxins. ... -
