Assembly of recombinant capsid proteins into virus-like particles (VLPs) still represents an interesting challenge in virus-based nanotechnologies. The structure of VLPs has gained importance for the development and design of new adjuvants and antigen carriers. The potential of Tobacco etch virus capsid protein (TEV CP) as adjuvant has not been evaluated to date. Two constructs for TEV CP expression in Escherichia coli were generated: a wild-type version (TEV-CP) and a C-terminal hexahistidine (His)-tagged version (His-TEV-CP). Although both versions were expressed in the soluble fraction of E. coli lysates, only His-TEV-CP self-assembled into micrometric flexuous filamentous VLPs. In addition, the His-tag enabled high yields and facilitated purification of TEV VLPs. These TEV VLPs elicited broader IgG2-specific antibody response against a novel porcine reproductive and respiratory syndrome virus (PRRSV) protein when compared to the potent IgG1 response induced by the protein alone. His-TEV CP was
The high prevalence of pre-existing anti-Ad5 immunity in human populations may substantially limit the immunogenicity and clinical utility of rAd5 vector-based vaccines for HIV-1 and other pathogens. Our studies demonstrate ,90% Ad5 seroprevalence in sub-Saharan Africa with median NAb titers ,10-fold higher than those found in the United States. These data suggest that rAd5 vectors should be engineered to evade dominant Ad5-specific NAbs before their use as vaccine vectors in the developing world. To determine the principal targets of Ad5-specific NAbs, we exploited the lack of detectable serologic cross-reactivity between Ad5 and Ad35 (8). Virus neutralization studies using capsid chimeric rAd5/rAd35 vectors and serum samples from both humans and mice demonstrated that Ad5-specific NAbs were directed primarily against the Ad5 hexon protein. Fiber-specific NAbs were detected at low frequencies in vitro but were substantially less efficient than hexon-specific NAbs at blunting rAd5 vaccine ...
Human papilloma viruses (HPV) are small DNA, non-enveloped, double-stranded and closed circular viruses. There are more than 150 HPV identified types. Genital HPV types are categorized according to their epidemiologic association with cervical cancer to high and low risk types. The high risk type HPV 16 is the most common in the world. we aimed to design a universal peptide based vaccine against HPV type 16 virus using Immunoinformatics Approach through prediction of highly conserved T and B-cell epitopes from the most abundant and highly immunogenic protein (L1 major capsid protein) derived from HPV type 16 strains all over the world. All sequences of the L1 major capsid protein were retrieved from NCBI database. Potentially continuous B and T cell epitopes were predicted using tools from immune epitope data base analysis resource (IEDB-AR). The Allergenicity of predicted epitopes was analyzed by AllerTOP Tool and the coverage was determined throughout the worlds. The B cell epitope 243KSEV246 ...
Samuel Campos, PhD, studies early events of Human Papillomavirus (HPV) infection. HPVs are small, non-enveloped DNA viruses that cause a variety of lesions ranging from benign waters to cervical cancers. Although over 100 types of HPVs have been identified, HPV16 is the most prevalent, and is alone responsible for more than 50% of cervical cancers in women worldwide. Dr. Campos and his lab study the mechanisms of HPV virus transmission at a cellular level, in hopes to discover new approaches for the prevention and treatment of HPV.HPV16 virions consist of an ~8kb circular dsDNA genome packaged into a ~60 nm protein capsid. The genome is condensed with cellular histones and exists in a chromatin-like state. The capsid is comprised of 72 pentamers of the major capsid protein L1 and up to 72 molecules of the minor capsid protein L2, localized along the inner capsid surface, within the central cavities beneath the L1 pentamers. Mature HPV16 virions exist in an oxidized state, with adjacent L1 ...
The utility of recombinant adenovirus serotype 5 (rAd5) vector-based vaccines for HIV-1 and other pathogens will likely be limited by the high prevalence of pre-existing Ad5-specific neutralizing Abs (NAbs) in human populations. However, the immunodominant targets of Ad5-specific NAbs in humans remain poorly characterized. In this study, we assess the titers and primary determinants of Ad5-specific NAbs in individuals from both the United States and the developing world. Importantly, median Ad5-specific NAb titers were ,10-fold higher in sub-Saharan Africa compared with the United States. Moreover, hexon-specific NAb titers were 4- to 10-fold higher than fiber-specific NAb titers in these cohorts by virus neutralization assays using capsid chimeric viruses. We next performed adoptive transfer studies in mice to evaluate the functional capacity of hexon- and fiber-specific NAbs to suppress the immunogenicity of a prototype rAd5-Env vaccine. Hexon-specific NAbs were remarkably efficient at ...
The mature HIV-1 conical core formation proceeds through highly regulated protease cleavage of the Gag precursor, which ultimately leads to substantial rearrangements of the capsid (CAp24) molecule involving both inter- and intra-molecular contacts of the CAp24 molecules. In this aspect, Asp51 which is located in the N-terminal domain of HIV-1 CAp24 plays an important role by forming a salt-bridge with the free imino terminus Pro1 following proteolytic cleavage and liberation of the CAp24 protein from the Pr55Gag precursor. Thus, previous substitution mutation of Asp51 to alanine (D51A) has shown to be lethal and that this invariable residue was found essential for tube formation in vitro, virus replication and virus capsid formation. We extended the above investigation by introducing three different D51 substitution mutations (D51N, D51E, and D51Q) into both prokaryotic and eukaryotic expression systems and studied their effects on in vitro capsid assembly and virus infectivity. Two substitution

We have presented several lines of evidence that the papillomavirus minor capsid protein mediates the endosomal escape of the viral genome. A C-terminal 23-amino-acid peptide from the L2 protein was identified that is essential for transit of the viral DNA across the endosomal membrane during papillomavirus infection. This peptide is also highly cytotoxic to bacteria, fungi, and mammalian cells after exogenous application due to membrane depolarization and permeabilization and induces the integration of GFP fusion proteins and full-length L2 protein into cellular membranes when expressed in mammalian cells, eventually resulting in cell death. Since the full-length L2 protein but not C-terminally mutated L2 nor L1 protein integrated into cellular membranes, an artificial effect of the observations with peptides and fusion proteins can be excluded. These critical functions render this peptide sequence indispensable for PV infection. The activity of this peptide is highest at modestly acidic pH, ...

It is becoming increasingly clear that mammalian cells can express a variety of factors that limit retroviral replication. One class of these factors blocks replication at a stage post-entry but prior to nuclear import and integration of the viral genome. Members of this family arc known as restriction factors. The best characterised member is the mouse gene hvl which determines susceptibility to infection by MLV. I-vl has two alleles known as Fvl" and Fv/ whose restriction characteristics determine the host range of different MLV strains. It has become apparent that the phenomenon of restriction is not limited to MLV and murine cells. HIV-1, as well as MLV is restricted at a post-entry step in a number of primate species including rhesus macaques. African green monkeys and owl monkeys. The Thm5 gene in these species is the main determinant of both HIV-1 and MLV restriction. Viral determinants of this restriction map to the virus capsid protein, however despite strong genetic ev idence, no ...
This section of the Laboratory of Cellular Oncologys website gives detailed technical information about the production and manipulation of human papillomavirus (HPV) and polyomavirus (PyV) based gene delivery vectors. Such vectors are also known as pseudoviruses. They are generated by co-expressing the two viral capsid proteins (L1 and L2 (HPVs) or VP1 and VP2/3 (PyVs)) using codon-modified expression constructs. The two capsid proteins are necessary and sufficient for intracellular packaging of reporter plasmids within mammalian 293TT cells. The resulting high-titer pseudovirus stocks can deliver packaged reporter plasmids to a wide variety of cell types in vitro and in vivo ...
Beginning in 2012, our understanding of human papillomavirus (HPV) subcellular trafficking has undergone a drastic paradigm shift. Work from multiple laboratories has revealed that HPV has evolved a unique means to deliver its viral genome (vDNA) to the cell nucleus, relying on a myriad of host cell proteins and processes. The major breakthrough finding from these recent endeavors was the realization of L2-dependent utilization of cellular sorting factors for the retrograde transport of vDNA away from degradative endo/lysosomal compartments to the Golgi, prior to mitosis-dependent nuclear accumulation of L2/vDNA. An overview of current models of HPV entry, subcellular trafficking, and the role of L2 during initial infection is provided below, highlighting unresolved questions and gaps in knowledge.

Summary Direct evidence linking the capsid protein to specific dsRNA segments from the three killer strains of Ustilago maydis virus (P1, P4, P6) is presented. The capsid proteins of the three strains cross-react immunologically, have similar mol. wt. and similar peptide maps after limited proteolysis. The capsid proteins from P1 and P4 were translated from their respective H2 dsRNA segments, whereas the capsid protein for P6 was translated from H1 dsRNA. These in vitro translation products were each precipitated by the antiserum to capsid proteins of all three strains, had similar mol. wt. and similar peptide maps. All in vitro translation products competed effectively with native capsid proteins of all of the three strains in immunocompetition assays. These results suggest that the three strains code for a similar capsid protein, and that the information for capsid protein resides in the H2 segment of strain P1 and P4, and in the H1 segment of strain P6.
... after access, yet sponsor elements involved in this procedure remain mainly mystery. MELK dictates ideal capsid disassembly through phosphorylation of Ser-149 in the multimerized HIV-1 primary, which prospects to effective virus-like Clonidine hydrochloride supplier cDNA activity in focus on cells. The phosphorylation-mimetic capsid mutation of Ser-149 triggered extravagant capsid disassembly and too-early finalization of invert transcription, and impeded nuclear admittance of HIV-1 cDNA, recommending the importance of well-ordered capsid disassembly in the early levels of virus-like duplication. This breakthrough discovery shall facilitate understanding of the useful hyperlink among pathogen uncoating, invert transcription and nuclear admittance, and is certainly anticipated to lead to developing a story technique for Helps therapy.

Spike-forming protein that mediates virion attachment to the host epithelial cell receptors and plays a major role in cell penetration, determination of host range restriction and virulence. Rotavirus entry into the host cell probably involves multiple sequential contacts between the outer capsid proteins VP4 and VP7, and the cell receptors. According to the considered strain, VP4 seems to essentially target sialic acid and/or the integrin heterodimer ITGA2/ITGB1 (By similarity).
Capsid protein VP1: Forms an icosahedral capsid of pseudo T=3 symmetry with capsid proteins VP2 and VP3. The capsid is 300 Angstroms in diameter, composed of 60 copies of each capsid protein and enclosing the viral positive strand RNA genome. Capsid protein VP1 mainly forms the vertices of the capsid. Capsid protein VP1 interacts with host cell receptor to provide virion attachment to target host cells. This attachment induces virion internalization. Tyrosine kinases are probably involved in the entry process. After binding to its receptor, the capsid undergoes conformational changes. Capsid protein VP1 N-terminus (that contains an amphipathic alpha-helix) and capsid protein VP4 are externalized. Together, they shape a pore in the host membrane through which viral genome is translocated to host cell cytoplasm. After genome has been released, the channel shrinks (By similarity).
Recently, recombinant baculoviruses have been used to show that expression of six herpes simplex virus type 1 genes results in the formation of capsid-like particles. We have applied cryoelectron microscopy and three-dimensional image reconstruction to establish their structural authenticity to a resolution of approximately 2.7 nm. By comparing capsids assembled with and without the expression of gene UL35, we have confirmed the presence of six copies of its product, VP26 (12 kDa), around each hexon tip. However, VP26 is not present on pentons, indicating that the conformational differences between the hexon and penton states of the major capsid protein, VP5, extend to the VP26 binding site. ...
The outer shell of the adenovirus capsid comprises three major types of protein (hexon, penton base and fiber) that perform the majority of functions facilitating the early stages of adenovirus infection. respect to the delivery of foreign molecules. Adenovirus capsid tasks in early illness The adenovirus (Ad) is definitely a non-enveloped, dsDNA disease whose outer shell of the icosahedral-shaped capsid is definitely comprises three major types of proteins: hexon, penton foundation and dietary fiber (Number 1). The hexon comprises the majority of the outer shell of the Ad capsid, forming 240 homotrimers that encapsidate the majority of the disease, including the viral genome and connected proteins [1]. The dietary fiber protrudes from each of the 12 vertices of the icosahedron, while the penton foundation lies at the base of each dietary fiber. These three capsid proteins contribute to the majority of activities required for the early phases of Ad infection. Number 1 Representation of ...
Herpes simplex type 1 virus (HSV-1) and bacteriophage λ capsids undergo considerable structural changes during self-assembly and DNA packaging. The initial steps of viral capsid self-assembly require weak, non-covalent interactions between the capsid subunits to ensure free energy minimization and error-free assembly. In the final stages of DNA packaging, however, the internal genome pressure dramatically increases, requiring significant capsid strength to withstand high internal genome pressures of tens of atmospheres. Our data reveal that the loosely formed capsid structure is reinforced post-assembly by the minor capsid protein UL25 in HSV-1 and gpD in bacteriophage λ. Using atomic force microscopy nano-indentation analysis, we show that the capsid becomes stiffer upon binding of UL25 and gpD due to increased structural stability. At the same time the force required to break the capsid increases by ∼70% for both herpes and phage. This demonstrates a universal and evolutionarily conserved function
We modified the capsid protein of a human enterovirus 71 (HEV71) belonging to subgenogroup C4 (HEV71-C4) to generate a mouse virulent strain, based on the genetic information derived from our previous subgenogroup B3 mouse-adapted virus. Infectious clone-derived mutant virus populations containing the capsid protein mutations VP1-Q145E and VP1-Q145G were generated by site-directed mutagenesis of an infectious clone of a subgenogroup C4 strain. Viruses expressing the VP1-Q145E were virulent in 5-day-old BALB/c mice with 100 % mortality rate observed. Skeletal muscle appears to be the primary site of replication of this virus with limb muscle showing severe myositis. Virus was also isolated from spleen, liver, heart and brain of infected mice. This study demonstrates that introducing a key mutation into the HEV71 VP1 capsid protein is able to generate a mouse virulent HEV71 strain from a different genogroup as well as providing an alternative strategy for the generation of mouse virulent HEV71.

To extend RNAi to the in vivo applications, we here demonstrated that the siRNA/capsid nanocarrier complexes could have tumor-specific targeting ability in vivo as well as the increased stability of siRNA during body circulation. When systemically administered, our siRNA/capsid nanocarrier complexes delivered siRNA to tumor tissues and efficiently suppressed RFP gene expression in tumor-bearing mice. The enhanced longevity of siRNA in vivo could be explained by shielding effect derived from the ...
The assembly and regulation of viral capsid proteins into highly ordered macromolecular complexes is essential for viral replication. Here, we utilize crystal structures of the capsid protein from the smallest and simplest known viruses capable of autonomously replicating in animal cells, circoviruses, to establish structural and mechanistic insights into capsid morphogenesis and regulation. The beak and feather disease virus, like many circoviruses, encode only two genes: a capsid protein and a replication initiation protein. The capsid protein forms distinct macromolecular assemblies during replication and here we elucidate these structures at high resolution, showing that these complexes reverse the exposure of the N-terminal arginine rich domain responsible for DNA binding and nuclear localization. We show that assembly of these complexes is regulated by single-stranded DNA (ssDNA), and provide a structural basis of capsid assembly around single-stranded DNA, highlighting novel binding ...

Title: HIV Capsid Pattern Sensing by the Host Cell. Abstract. The mature HIV capsid provides a range of interfaces recognizable by host factors and, during its post-entry journey from the cell periphery to the nucleus, the virus encounters a variety of them-some co-opted for optimal infectivity, others evolutionarily designed to prevent infection. A common feature of these interactions is the ability of capsid pattern sensing by the host. This feature allows a host factor to preferably bind intact capsid cores that contain the viral genome, and to avoid the numerous unassembled CA molecules present in the cell. However, high-order capsid recognition is challenging to study in vitro. Here I present various protein-engineering strategies for the production of a repertoire of soluble capsid assemblies and the use of these assemblies in the study of native capsid structure and capsid-host factor interactions. Our studies contribute to a better understanding of the diverse molecular mechanisms by ...

An interaction between the HSV-1 UL25 capsid protein and cellular microtubule-associated protein was found using a yeast two-hybrid screen and β-D-galactosidase activity assays. Immunofluorescence microscopy of the UL25 protein demonstrated its co-localization with cellular microtubule-associated protein in the plasma membrane. Further investigations with deletion mutants suggest that UL25 is likely to have a function in the nucleus.
Herpes simplex virus type 1 (HSV-1) capsids are initially assembled with an interior proteins scaffold. capsids upon DNA product packaging we show that VP24 (formulated with the protease area) is certainly quantitatively retained. To research elements managing UL26 capsid incorporation and retention we used a mutant computer virus that fails to express UL26.5 (?virus). Purified ?B capsids showed altered sucrose gradient sedimentation and lacked the dense scaffold core seen in micrographs of wild-type B capsids but contained capsid shell proteins in wild-type amounts. Despite C-terminal sequence identity between UL26 and UL26.5 ?capsids lacking UL26.5 products did not contain compensatory high levels of UL26 proteins. Therefore HSV capsids can be maintained and/or assembled on a minimal scaffold made up of only wild-type levels of UL26 proteins. In contrast to UL26.5 increased expression of UL26 did not compensate for the ?growth defect. While indirect these findings are consistent with the view ...
Abstract: Viruses self-assemble from identical capsid proteins and their genome consisting, for example, of a long single stranded (ss) RNA. For a big class of T = 3 viruses capsid proteins have long positive N-terminal tails. We explore the role played by the Coulomb interaction between the brush of positive N-terminal tails rooted at the inner surface of the capsid and the negative ss RNA molecule. We show that viruses are most stable when the total contour length of ss RNA is close to the total length of the tails. For such a structure the absolute value of the total RNA charge is approximately twice larger than the charge of the capsid. This conclusion agrees with structural data. ...
It is relatively easy to determine that the poliovirus capsid is made up of just four proteins, and that the four capsid proteins VP1, VP2, VP3, and VP4 are present in equimolar amounts in the capsid. Groups of five copies of each protein are arranged at each of the 12 vertices of the icosahedral capsid see Chapters 5 and 15 . If the proteins are uniformly labeled with radioactive amino acids, more radioactivity will be in each large polypeptide chain than in each small one. A gel fractionation.... ...
Viruses are nanosized, genome-filled protein containers with remarkable thermodynamic and mechanical properties. They form by spontaneous self-assembly inside the crowded, heterogeneous cytoplasm of infected cells. Self-assembly of viruses seems to obey the principles of thermodynamically reversible self-assembly but assembled shells (capsids) strongly resist disassembly. Following assembly, some viral shells pass through a sequence of coordinated maturation steps that progressively strengthen the capsid. Viral shells have effective Youngs moduli ranging from that of polyethylene to that of plexiglas. Some of them can withstand internal osmotic pressures that are tens of atmospheres." (Roos et al. 2010:733). "Viruses do not carry out metabolic activity and rely entirely on host-cell molecular machinery for reproduction. This absence of metabolic and reproductive activity suggests that, unlike cells, the assembly of viruses could perhaps be understood on the basis of equilibrium ...

Replication deficient adenoviruses type 5 (Ad5) are widely used vectors for cancer gene therapy. The retargeting of Ad5 is achieved by incorporation of a targeting motifs into the adenovirus capsid proteins, mostly in the HI-loop of fiber or hexon hypervariable region 5 (HVR5). Increased expression of αv integrins has been frequently shown in tumor cells as compared to normal cells. The targeting motif within Ad5 that retargets its transduction to cells expressing αv integrins is RGD. One of the strategies of tumor gene therapy is inhibition of angiogenesis. Endothelial cells in angiogenesis express aminopeptidase N (APN) which binds targeting motifs containing NGR. It is known that different amino acid environment and/or cysteine residues flanking targeting peptides RGD and NGR influence the affinity and specificy of binding to corresponding receptors. The aim of this work was to investigate the existance of disulfide bond/s in two replication deficient Ad5 vectors: (i) Ad5HCRGDC containing ...

This give the virus specificity, meaning that it will only be able to infect a certain host range. Once the viral genome is injected into the cell, then for a DNA phage, bacterial cells RNAP begins transcribing RNAs from certain promoters. The first class of viral genes is intermediate-early genes. Following translation of these genes, the early viral genes are transcribed. These genes encode proteins which get virus ready for DNA replication.. After DNA replication, usually into hundreds of copies, the late viral RNAs are made and translated into proteins. These act as structural components, either for capsid formation or cleaving and packaging of DNA into capsid, or to form the receptor on the capsid surface.. Nucleocapsid:. ...

Now that my lab is fully equipped, Im taking on rotation students. Unfortunately, with the pandemic, its harder to have one-on-one meetings where I can sit down and walk the new students through every method. Furthermore, why repeat teaching the same thing to multiple students when I can just make an initial written record that everyone can reference and just ask me questions about? Thus, heres my instructional tutorial on how I design primers in the lab.. First, its good to start out by making a new benchling file for whatever youre trying to engineer. If youre just making a missense mutation, then you can start out by copying the map for the plasmid youre going to use as a template. Today, well be mutating a plasmid called "G619C_AttB_hTrim-hCPSF6(301-358)-IRES-mCherry-P2A-PuroR" to encode the F321N mutation the CPSF6 region. This should abrogate the binding of this peptide to the HIV capsid protein. Eventually every plasmid in the lab gets a unique identifier based on the order it ...

An important part of a virus is its protein shell, called the viral capsid, that protects the viral genome. While the viral capsids of viruses in the family of Papovaviridae are usually spherical, their protein building blocks are known to assemble also as tubular structures [Kiselev, N.A., Klug, A., 1969. J. Mol. Biol. 40, 155]. In Twarock [2004. J. Theor. Biol. 226, 477] Viral Tiling Theory has been introduced for the structural description of the protein stoichiometry of the spherical capsids in this family. This approach is extended here to the tubular case and is used to classify the surface lattices of tubular structures in the family of Papovaviridae. The predictions of the theory are compared with the experimental results in Kiselev and Klug [1969. J. Mol. Biol. 40, 155]. ...
