Abstract
Abstract
Baculoviruses are insect pathogens widely used as biotechnological tools in different fields of life sciences and technologies. The particular biology of these entities (biosafety viruses 1; large circular double-stranded DNA genomes, infective per se; generally of narrow host range on insect larvae; many of the latter being pests in agriculture) and the availability of molecular-biology procedures (e.g., genetic engineering to edit their genomes) and cellular resources (availability of cell lines that grow under in vitro culture conditions) have enabled the application of baculoviruses as active ingredients in pest control, as systems for the expression of recombinant proteins (Baculovirus Expression Vector Systems—BEVS) and as viral vectors for gene delivery in mammals or to display antigenic proteins (Baculoviruses applied on mammals—BacMam). Accordingly, BEVS and BacMam technologies have been introduced in academia because of their availability as commercial systems and ease of use and have also reached the human pharmaceutical industry, as incomparable tools in the development of biological products such as diagnostic kits, vaccines, protein therapies, and—though still in the conceptual stage involving animal models—gene therapies. Among all the baculovirus species, the Autographa californica multiple nucleopolyhedrovirus has been the most highly exploited in the above utilities for the human-biotechnology field. This review highlights the main achievements (in their different stages of development) of the use of BEVS and BacMam technologies for the generation of products for infectious and noninfectious human diseases. Key points • Baculoviruses can assist as biotechnological tools in human health problems. • Vaccines and diagnosis reagents produced in the baculovirus platform are described. • The use of recombinant baculovirus for gene therapy–based treatment is reviewed.

AIV polyantigen epitope expressed by recombinant baculovirus induces a systemic immune response in chicken and mouse models. Virol J 2020; 17:121. [PMID: 32758272 PMCID: PMC7403573 DOI: 10.1186/s12985-020-01388-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Accepted: 07/15/2020] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND The protective efficacy of avian influenza virus (AIV) vaccines is unsatisfactory due to the presence of various serotypes generated by genetic reassortment. Thus, immunization with a polyantigen chimeric epitope vaccine may be an effective strategy for protecting poultry from infection with different AIV subtypes. METHODS Baculovirus has recently emerged as a novel and attractive gene delivery vehicle for animal cells. In the present study, a recombinant baculovirus BmNPV-CMV/THB-P10/CTLT containing a fused codon-optimized sequence (CTLT) of T lymphocyte epitopes from H1HA, H9HA, and H7HA AIV subtypes, and another fused codon-optimized sequence (THB) of Th and B cell epitopes from H1HA, H9HA, and H7HA AIV subtypes, driven by a baculovirus P10 promoter and cytomegalovirus CMV promoter, respectively, was constructed. RESULTS Western blotting and cellular immunofluorescence demonstrated that the CTLT (THB) can be expressed in rBac-CMV/THB-P10/CTLT-infected silkworm cells (mammalian HEK293T cells). Furthermore, the recombinant virus, rBac-CMV-THB-CTLT, was used to immunize both chickens and mice. CONCLUSIONS The results of an indirect ELISA, immunohistochemistry, and T lymphocyte proliferation assay indicated that specific humoral and cellular responses were detected in both chicken and mice. These results suggest that rBac-CMV/THB-P10/CTLT can be developed as a potential vaccine against different AIV subtypes.

Abstract
Background Poultry vaccine has limited choices of adjuvants and is facing severe threat of infectious diseases due to ineffective of widely used commercial vaccines. Thus, development of novel adjuvant that offers safe and effective immunity is of urgent need. Materials and Methods The present research engineers a novel chicken adjuvant with potent immune-potentiating capability by incorporating avian toll-like receptor 21 (TLR21) agonist CpG ODN 2007 with a poly(lactic-co-glycolic acid) (PLGA)-based hollow nanoparticle platform (CpG-NP), which subsequently assessed ex vivo and in vivo. Results CpG-NPs with an average diameter of 164 nm capable of sustained release of CpG for up to 96 hours were successfully prepared. With the ex vivo model of chicken bone marrow-derived dendritic cells (chBMDCs), CpG-NP was engulfed effectively and found to induce DC maturation, promoting dendrite formation and upregulation of CD40, CD80 and CCR7. In addition to enhanced expression of IL-1β, IL-6, IL-12 and IFN-γ, 53/84 immune-related genes were found to be stimulated in CpG-NP-treated chBMDCs, whereas only 39 of such genes were stimulated in free CpG-treated cells. These upregulated genes suggest immune skewing toward T helper cell 1 bias and evidence of improved mucosal immunity upon vaccination with the CpG-NP. The CpG-NP-treated chBMDCs showed protective effects to DF-1 cells against avian influenza virus H6N1 infection. Upon subsequent coupling with infectious bronchitis virus subunit antigen administration, chickens were immunostimulated to acquire higher humoral immune response and protective response against viral challenge. Conclustion This work presents a novel hollow CpG-NP formulation, demonstrating effective and long-lasting immunostimulatory ability ex vivo and in vivo for chickens, as systemically compared to free CpG. This enhanced immune stimulation benefits from high stability and controlled release of internal component of nanoparticles that improve cellular delivery, lymphoid organ targeting and sustainable DC activation. CpG-NP has broad application potential in antiviral and vaccine development.

Hsieh MS, Chang YC, He JL, Juang RH. Positive charge of Arg-201 on hemagglutinin is required for the binding of H6N1 avian influenza virus to its target through a two-step process. Virus Res 2019; 265:132-137. [PMID: 30926385 DOI: 10.1016/j.virusres.2019.03.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2019] [Revised: 02/17/2019] [Accepted: 03/21/2019] [Indexed: 11/29/2022]
Abstract
In our previous study, we produced a monoclonal antibody EB2 that recognized an epitope in the HA1 domain on the hemagglutinin (HA) of H6N1 influenza virus (A/chicken/Taiwan/2838 V/00). The residue Arg-201 (R201) on this epitope was protected by the glycan at Asn-167 (N167) from tryptic digestion; therefore, the infectivity of the virus was retained. R201 was extremely conserved in various subtypes of the influenza virus. To explore the role of R201 and the protecting glycan, we developed a bi-cistronic baculovirus expression system for the production of H6HA1 and H6HA0 (nearly full-length HA), which were glycosylated in insect cells. The expressed H6HA1 was mostly found in the trimeric form, and the H6HA0 protein was only found in the monomeric form. The trimeric H6HA1 was resistant to tryptic digestion; however, it could not bind to fetuin, a glycoprotein containing sialylated N-linked and O-linked glycans. By contrast, the monomeric H6HA0 could bind to fetuin but was sensitive to tryptic digestion. We found that the positive charge on R201 was critical for binding HA to the negatively charged surface of host cells because the mutant R201A of H6HA0 lost its binding capacity substantially. Moreover, this binding capacity was dependent on the pH value and inhibited by free electrically charged amino acids. We propose a two-step model for binding the influenza virus with a host cell. The first step involved the specific recognition of the receptor binding site on HA to the sialylated glycan on the host cell. After the virus is engulfed by the acidic endosome, R201 could bind to the cell surface with stronger interactions and trigger the fusion process.
