OBJECTIVE(S) Infection by high-risk papillomavirus is regarded as the major risk factor in the development of cervical cancer. Recombinant DNA technology allows expression of the L1 major capsid protein of HPV in different expression systems, which has intrinsic capacity to self-assemble into viral-like particles (VLP). VLPS are non-infectious, highly immunogenic and can elicit neutralizing ant...
introduction: in recent years, influenza viruses have caused moderate to severe infections all around the world while so far there is no influenza vaccine that can protect people with only one dose of injection. in this regard, producing a universal vaccine based on virus-like-particles (vlp) could be an ideal approach. methods: in this study, the full-length orf of influenza hemagglutinin (ha...
objective: influenza virus a (h1n1) is an important subtype of the influenza respiratory viruses, which has important worldwide implications. hemagglutinin (ha), an important viral antigen, is responsible for binding to human cell receptors leading to an onset of the disease process. considering the critical role of viral attachment, this study focuses on the extraction and cloning of ha and it...
Open reading frame 76 of Bombyx mori nucleopolyhedrovirus (BmNPV), designated as Bm76, is a gene whose function is completely unknown. With EGFP fused to the 3' terminal of Bm76 as the reporter gene and BmNPV bacmid as the expression vector, a recombinant bacmid was successfully constructed expressing Bm76-EGFP fusion protein under the control of polyhedrin promoter in Bombyx mori cells (Bm cel...
Influenza virus A (H1N1) is an important subtype of influenza virus that makes numerous consequences throughout the world. In the first step of viral attachment, main antigenic site of the HA1 domain from the globular head of hemagglutinin (HA) binds to human cell receptors, starting the disease process. In order to produce recombinant subunit protein vaccines, we focus on the nucleotide sequen...
Background: The importance of viral protein-2 (VP2) of canine parvovirus (CPV) in binding to human cancer cells, production of veterinary vaccines and diagnostic kits has motivated several researches on producing this protein.Objectives: Our purpose was to construct recombinant bacmid shuttle vectors expressing VP2 of CPV using Bac-to-Bac baculoviral expr...
BACKGROUND The hepatitis E virus (HEV) accounts for hepatitis E infection with relatively high mortality rate in pregnant women that can lead to fulminant hepatitis. The baculovirus expression system (BES) has the capability to produce high-level recombinant proteins and could be useful for vaccine designing. OBJECTIVES The aim of this study was designing a recombinant hepatitis E virus ORF2 ...
conclusions: the recombinant baculovirus constructed in this work has proper characteristics to produce h5n1 influenza virus-like particles in sf9 cells. results: restriction map of pfastbacihnm1 plasmid confirmed the fidelity of the clone. the pcr carried out on the recombinant bacmids as template indicated that a proper homologous recombination has occurred between pfastbacihnm1 donor plasmid...
conclusions the results of the present study showed that the baculovirus expression system (sf9 cells) was able to express truncated orf2 and truncated orf2-nsp4 proteins as a potential candidate vaccine. background the hepatitis e virus (hev) accounts for hepatitis e infection with relatively high mortality rate in pregnant women that can lead to fulminant hepatitis. the baculovirus expression...
This study employed a Bac-to-Bac/Bombyx mori bioreactor to mass-produce immunogenic urease subunit B (UreB) from Helicobacter pylori. The signal peptide bombyxin from B. mori was used to promote secretory expression to improve expression levels and was designed and integrated into the UreB gene to generate the Bacmid/BmNPV/(signal peptide)-UreB baculovirus expression system. To determine whethe...
