Abstract
Bocaparvovirus is an expansive genus of the Parvovirinae, with a wide range of vertebrate hosts. This study investigates Canine minute virus (CnMV), Rat bocavirus (RBoV), and Porcine bocavirus 1 (PBoV1). Both CnMV and PBoV1 have been found in gastrointestinal infections in their respective hosts, with CnMV responsible for spontaneous abortions in dogs, while PBoV has been associated with encephalomyelitis in piglets. The pathogenicity of the recently identified RBoV is currently unknown. To initiate the characterization of these viruses, their capsids structures were determined by cryo-electron microscopy at resolutions ranging from 2.3 to 2.7 Å. Compared to other parvoviruses, the CnMV, PBoV1, and RBoV capsids showed conserved features, such as the channel at the fivefold symmetry axis. However, major differences were observed at the two- and threefold axes. While CnMV displays prominent threefold protrusions, the same region is more recessed in PBoV1 and RBoV. Furthermore, the typical twofold axis depression of parvoviral capsids is absent in CnMV or very small in PBoV and RBoV. These capsid structures extend the structural portfolio for the Bocaparvovirus genus and will allow future characterization of these pathogens on a molecular level. This is important, as no antivirals or vaccines exist for these viruses.

Abstract
The baculovirus expression vector system (BEVS) delivers high yield heterologous protein expression and is widely used in academic and industrial R&D. The proteins produced enable many applications including structure/function analysis, drug screening and manufacture of protein therapeutics. Vital cellular functions are controlled by multi-protein complexes, MultiBac, a BEVS specifically designed for heterologous multigene delivery and expression, has unlocked many of these machines to atomic resolution studies. Baculovirus can accommodate very large foreign DNA cargo for faithful delivery into a target host cell, tissue or organism. Engineered MultiBac variants exploit this valuable feature for delivery of customized multifunctional DNA circuitry in mammalian cells and for production of virus-like particles for vaccines manufacture. Here, latest developments and applications of the MultiBac system are reviewed.

Abstract
The Baculovirus Expression Vector System (BEVS) is a workhorse for recombinant protein expression for over thirty-five years. Ever since it was first used to overexpress the human IFN-β protein, the system has been engineered and modified several times for quick and easy expression and scale-up of the recombinant proteins. Multiple gene assemblies performed on the baculovirus genome using synthetic biology methods lead to optimized overexpression of the multiprotein complexes. Nowadays, several commercially available BEVS platforms offer a variety of customizable features, and often it is confusing which one to choose for a novice user. This short review is intended to be a one-stop guide to the commercially available baculovirus technology for heterologous protein expression in the insect cells, which users can refer to choose from popular and desirable BEVS products or services.

Abstract
Several members of the Protoparvovirus genus, capable of infecting humans, have been recently discovered, including cutavirus (CuV) and tusavirus (TuV). To begin the characterization of these viruses, we have used cryo-electron microscopy and image reconstruction to determine their capsid structures to ~2.9 Å resolution, and glycan array and cell-based assays to identify glycans utilized for cellular entry. Structural comparisons show that the CuV and TuV capsids share common features with other parvoviruses, including an eight-stranded anti-parallel β-barrel, depressions at the icosahedral 2-fold and surrounding the 5-fold axes, and a channel at the 5-fold axes. However, the viruses exhibit significant topological differences in their viral protein surface loops. These result in three separated 3-fold protrusions, similar to the bufaviruses also infecting humans, suggesting a host-driven structure evolution. The surface loops contain residues involved in receptor binding, cellular trafficking, and antigenic reactivity in other parvoviruses. In addition, terminal sialic acid was identified as the glycan potentially utilized by both CuV and TuV for cellular entry, with TuV showing additional recognition of poly-sialic acid and sialylated Lewis X (sLeXLeXLeX) motifs reported to be upregulated in neurotropic and cancer cells, respectively. These structures provide a platform for annotating the cellular interactions of these human pathogens.

Abstract
INTRODUCTION The need to develop new drugs for the control of pathogenic microorganisms has redoubled efforts to prospect for antimicrobial peptides (AMPs) from natural sources and to characterize its structure and function. These molecules present a broad spectrum of action against different microorganisms and frequently present promiscuous action, with anticancer and immunomodulatory activities. Furthermore, AMPs can be used as biopharmaceuticals in the treatment of hospital-acquired infections and other serious diseases with relevant social and economic impacts.Areas covered: The low yield and the therefore difficult extraction and purification process in AMPs are problems that limit their industrial application and scientific research. Thus, optimized heterologous expression systems were developed to significantly boost AMP yields, allow high efficiency in purification and structural optimization for the increase of therapeutic activity.Expert opinion: This review provides an update on recent developments in the recombinant production of ribosomal and non-ribosomal synthesis of AMPs and on strategies to increase the expression of genes encoding AMPs at the transcriptional and translational levels and regulation of the post-translational modifications. Moreover, there are detailed reports of AMPs that have already reached marketable status or are in the pipeline under advanced stages of preclinical testing.

Abstract
Baculovirus expression is a time-tested technique to produce proteins in insect cells, in high quality and quantity for a range of applications. MultiBac is a baculovirus expression system we developed originally for producing multiprotein complexes comprising many subunits, for structural and mechanistic studies. First introduced in 2004, MultiBac is now in use in many laboratories worldwide, accelerating research programmes in academia and industry. We have continuously optimized our MultiBac system, providing customized reagents and standard operating protocols to facilitate its use also by non-specialists. More recently, we have generated MultiBac genomes tailored for specific purposes, for example, to produce humanized glycoproteins, high-value pharmaceutical targets including kinases, viral polymerases, and virus-like particles (VLPs) as promising vaccine candidates. By altering the host tropism of the baculovirion, we created MultiBacMam, a heterologous DNA delivery toolkit to target mammalian cells, tissues and organisms. Introducing CRISPR/Cas modalities, we set the stage for large-scale genomic engineering applications utilizing this high-capacity DNA delivery tool. Exploiting synthetic biology approaches and bottom-up design, we engage in optimizing the properties of our baculoviral genome, also to improve manufacturing at scale. Here we provide a perspective of our MultiBac system and its developments, past, present and future.

Abstract
Neospora caninum is a causative and transmissible agent of dog and bovine neosporosis. The resulting reproductive failures in infected cattle lead to significant economic losses worldwide. However, there is no satisfactory treatment or vaccine currently available to combat this pathogen. Thus, the development of appropriate vaccines to manage its infection and transmission is urgently needed. In this study, we expressed Rous sarcoma virus-like particles (RSV-LP) that displayed dual N. caninum antigens in silkworms. The antigen candidates are modified by adding a transmembrane domain of GP64 protein from Bombyx mori nucleopolyhedrovirus (BmNPV) to the C-terminus of surface antigen 1 (NcSAG1) and SAG1-related sequence 2 (NcSRS2). The NcSRS2 alone or the NcSAG1/NcSRS2 bivalent form displaying RSV-LPs were purified using sucrose density gradient centrifugation. These purified VLPs were then used for immunizations in gerbils, Meriones unguiculatus, to evaluate the anti-N. caninum effects in vivo. The results demonstrated that antigens displaying RSV-LPs in immunized gerbils produced the antigen-specific antibody, leading to a relatively lower parasite load after infections of N. caninum. To the best of our knowledge, this is the first study to present an RSV-LP vaccine displaying bivalent antigens from neosporosis. Taken together, our strategy suggests that silkworm-expressed virus-like particles (VLPs) are promising bivalent vaccine candidates against N. caninum infections.

Abstract
Pioneering bioinformatic analysis using sequence data revealed that teneurins evolved from bacterial tyrosine-aspartate (YD)-repeat protein precursors. Here, we discuss how structures of the C-terminal domain of teneurins, determined using X-ray crystallography and electron microscopy, support the earlier findings on the proteins’ ancestry. This chapter describes the structure of the teneurin scaffold with reference to a large family of teneurin-like proteins that are widespread in modern prokaryotes. The central scaffold of modern eukaryotic teneurins is decorated by additional domains typically found in bacteria, which are re-purposed in eukaryotes to generate highly multifunctional receptors. We discuss how alternative splicing contributed to further diversifying teneurin structure and thereby function. This chapter traces the evolution of teneurins from a structural point of view and presents the state-of-the-art of how teneurin function is encoded by its specific structural features.

Abstract
To stop the spread of future epidemics and meet infant vaccination demands in low- and middle-income countries, flexible, rapid and low-cost vaccine development and manufacturing technologies are required. Vaccine development platform technologies that can produce a wide range of vaccines are emerging, including: a) humanized, high-yield yeast recombinant protein vaccines; b) insect cell-baculovirus ADDomer vaccines; c) Generalized Modules for Membrane Antigens (GMMA) vaccines; d) RNA vaccines. Herein, existing and future platforms are assessed in terms of addressing challenges of scale, cost, and responsiveness. To assess the risk and feasibility of the four emerging platforms, the following six metrics are applied: 1) technology readiness; 2) technological complexity; 3) ease of scale-up; 4) flexibility for the manufacturing of a wide range of vaccines; 5) thermostability of the vaccine product at tropical ambient temperatures; and 6) speed of response from threat identification to vaccine deployment. The assessment indicated that technologies in the order of increasing feasibility and decreasing risk are the yeast platform, ADDomer platform, followed by RNA and GMMA platforms. The comparative strengths and weaknesses of each technology are discussed in detail, illustrating the associated development and manufacturing needs and priorities.

Abstract
Purified recombinant proteins are key reagents in academic and industrial research. The ability to make these proteins quickly often relies on the availability of higher eukaryotic cell hosts such as insect and mammalian cells where there is a very wide range of post-translational modifications, protein folding and trafficking pathways. This enables the generation of many proteins that cannot be made in microbial hosts. In this article we outline some of the most commonly used methods to express recombinant proteins in insect and mammalian cells.

Abstract
The MultiBac baculovirus/insect cell expression vector system was conceived as a user-friendly, modular tool-kit for producing multiprotein complexes for structural biology applications. MultiBac has allowed the structure and function of many molecular machines to be elucidated, including previously inaccessible high-value drug targets. More recently, MultiBac developments have shifted to customized baculoviral genomes that are tailored for a range of applications, including synthesizing artificial proteins by genetic code expansion. We review some of these developments, including the ongoing rewiring of the MultiBac system for mammalian applications, notably CRISPR/Cas9-mediated gene editing.
