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 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 ... -
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 ... -
Highly efficient production of rabies virus glycoprotein G ectodomain in Sf9 insect cells
(Springer, 2019-11)In the present study, we developed a complete process to produce in insect cells a high amount of the ectodomain of rabies virus glycoprotein G (GE) as suitable antigen for detecting anti-rabies antibodies. Using the ... -
Immunomodulatory effect of baculovirus in chickens : how it modifies the immune response against infectious bursal disease virus
(2016)Several reports have shown that baculoviruses (BVs) have strong adjuvant properties on the mammalian immune system. Recent studies of our group demonstrated the ability of BV to stimulate the innate immunity in chickens. ... -
The localization of a heterologous displayed antigen in the baculovirus-budded virion determines the type and strength of induced adaptive immune response
(2017-05)In the search of strategies of presentation of heterologous antigens to elicit humoral or cellular immune responses that modulate and properly potentiate each type of response, researchers have been studying baculovirus ... -
Novel biotechnological platform based on baculovirus occlusion bodies carrying Babesia bovis small antigenic peptides for the design of a diagnostic enzyme-linked immunosorbent assay (ELISA)
(Springer, 2018-01)Baculoviruses are large DNA virus of insects principally employed in recombinant protein expression. Its ability to form occlusion bodies (OBs), which are composed mainly of polyhedrin protein (POLH), makes them ... -
P26 enhances baculovirus gene delivery by modulating the mammalian antiviral response
(Springer, 2023-08)Poxins are poxviral proteins that act by degrading 2´3´-cGAMP, a key molecule of cGAS-STING axis that drives and amplifies the antiviral response. Previous works have described some poxin homologous among lepidopteran and ... -
Recombinant occlusion bodies of baculovirus as carriers of a nonstructural protein of foot-and-mouth disease virus
(Springer, 2018-11)Here, we developed a diagnostic ELISA for foot-and-mouth disease using recombinant occlusion bodies (rOBs) of baculovirus. We fused Δ3AB1–3, a polypeptide derived from non-structural proteins of foot-and-mouth disease ... -
Successful production of the potato antimicrobial peptide Snakin-1 in baculovirus-infected insect cells and development of specific antibodies
(2017)Background: Snakin-1 (StSN1) is a broad-spectrum antimicrobial cysteine-rich peptide isolated from Solanum tuberosum. Its biotechnological potential has been already recognized since it exhibits in vivo antifungal and ... -
The autographa californica multiple nucleopolyhedrovirus Ac12: A non-essential F box-like protein that interacts with cellular SKP1 component of the E3 ubiquitin ligase complex
(Elsevier, 2019-01)The Autographa californica multiple nucleopolyhedrovirus (AcMNPV) ac12 gene, which is conserved in ten other baculovirus, codes a predicted 217 amino acid protein of unknown function. In this study, we investigated the ... -
TLR9 activation is required for cytotoxic response elicited by baculovirus capsid display
