Abstract
SARS-CoV-2 variants that attenuate antibody neutralization could jeopardize vaccine efficacy. We recently reported the protective activity of an intranasally administered spike protein-based chimpanzee adenovirus-vectored vaccine (ChAd-SARS-CoV-2-S) in animals, which has advanced to human trials. Here, we assessed its durability, dose response, and cross-protective activity in mice. A single intranasal dose of ChAd-SARS-CoV-2-S induced durably high neutralizing and Fc effector antibody responses in serum and S-specific IgG and IgA secreting long-lived plasma cells in the bone marrow. Protection against a historical SARS-CoV-2 strain was observed across a 100-fold vaccine dose range and over a 200-day period. At 6 weeks or 9 months after vaccination, serum antibodies neutralized SARS-CoV-2 strains with B.1.351, B.1.1.28, and B.1.617.1 spike proteins and conferred almost complete protection in the upper and lower respiratory tracts after challenge with variant viruses. Thus, in mice, intranasal immunization with ChAd-SARS-CoV-2-S provides durable protection against historical and emerging SARS-CoV-2 strains.

Abstract
The coronavirus disease 2019 pandemic has made deployment of an effective vaccine a global health priority. We evaluated the protective activity of a chimpanzee adenovirus-vectored vaccine encoding a prefusion stabilized spike protein (ChAd-SARS-CoV-2-S) in challenge studies with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and mice expressing the human angiotensin-converting enzyme 2 receptor. Intramuscular dosing of ChAd-SARS-CoV-2-S induces robust systemic humoral and cell-mediated immune responses and protects against lung infection, inflammation, and pathology but does not confer sterilizing immunity, as evidenced by detection of viral RNA and induction of anti-nucleoprotein antibodies after SARS-CoV-2 challenge. In contrast, a single intranasal dose of ChAd-SARS-CoV-2-S induces high levels of neutralizing antibodies, promotes systemic and mucosal immunoglobulin A (IgA) and T cell responses, and almost entirely prevents SARS-CoV-2 infection in both the upper and lower respiratory tracts. Intranasal administration of ChAd-SARS-CoV-2-S is a candidate for preventing SARS-CoV-2 infection and transmission and curtailing pandemic spread.

Abstract
Hemophilia B (HB) is a life-threatening inherited disease caused by mutations in the FIX gene, leading to reduced protein function and abnormal blood clotting. Due to its monogenic nature, HB is one of the primary targets for gene therapy. Indeed, successful correction of HB has been shown in clinical trials using gene therapy approaches. However, application of these strategies to non-adult patients is limited due to high cell turnover as young patients develop, resulting in vector dilution and subsequent loss of therapeutic expression. Gene editing can potentially overcome this issue by permanently inserting the corrective gene. Integration allows replication of the therapeutic transgene at every cell division and can avoid issues associated with vector dilution. In this study, we explored adenovirus as a platform for corrective CRISPR/Cas9-mediated gene knock-in. We determined as a proof-of-principle that adenoviral delivery of CRISPR/Cas9 is capable of corrective gene addition, leading to long-term augmentation of FIX activity and phenotypic correction in a murine model of juvenile HB. While we found on-target error-free integration in all examined samples, some mice also contained mutations at the integration target site. Additionally, we detected adaptive immune responses against the vector and Cas9 nuclease. Overall, our findings show that the adenovirus platform is suitable for gene insertion in juveniles with inherited disease, suggesting this approach may be applicable to other diseases.

Abstract
INTRODUCTION Cellular and humoral immune responses are both involved in protection against Plasmodium infections. The only malaria vaccine available, RTS,S, primarily induces short-lived antibodies and targets only a pre-erythrocytic stage antigen. Inclusion of erythrocytic stage targets and enhancing cellular immunogenicity are likely necessary for developing an effective second-generation malaria vaccine. Adenovirus vectors have been used to improve the immunogenicity of protein-based vaccines. However, the clinical assessment of adenoviral-vectored malaria vaccines candidates has shown the induction of robust Plasmodium-specific CD8+ but not CD4+ T cells. Signal peptides (SP) have been used to enhance the immunogenicity of DNA vaccines, but have not been tested in viral vector vaccine platforms. OBJECTIVES The objective of this study was to determine if the addition of the SP derived from the murine IgGκ light chain within a recombinant adenovirus vector encoding a multistage P. vivax vaccine candidate could improve the CD4+ T cell response. METHODS In this proof-of-concept study, we immunized CB6F1/J mice with either the recombinant simian adenovirus 36 vector containing the SP (SP-SAd36) upstream from a transgene encoding a chimeric P. vivax multistage protein or the same SAd36 vector without the SP. Mice were subsequently boosted twice with the corresponding recombinant proteins emulsified in Montanide ISA 51 VG. Immunogenicity was assessed by measurement of antibody quantity and quality, and cytokine production by T cells after the final immunization. RESULTS The SP-SAd36 immunization regimen induced significantly higher antibody avidity against the chimeric P. vivax proteins tested and higher frequencies of IFN-γ and IL-2 CD4+ and CD8+ secreting T cells, when compared to the unmodified SAd36 vector. CONCLUSIONS The addition of the murine IgGκ signal peptide significantly enhances the immunogenicity of a SAd36 vectored P. vivax multi-stage vaccine candidate in mice. The potential of this approach to improve upon existing viral vector vaccine platforms warrants further investigation.

Abstract
Serum deficiency diseases such as alpha-1-antitrypsin deficiency are characterized by reduced function of serum proteins, caused by deleterious genetic mutations. These diseases are promising targets for genetic interventions. Gene therapies using viral vectors have been used to introduce correct copies of the disease-causing gene in preclinical and clinical studies. However, these studies highlighted that disease-alleviating gene expression is lost over time. Integration into a specific chromosomal site could provide lasting therapeutic expression to overcome this major limitation. Additionally, targeted integration could avoid detrimental mutagenesis associated with integrative vectors, such as tumorigenesis or functional gene perturbation. To test if adenoviral vectors can facilitate long-term gene expression through targeted integration, we somatically incorporated the human alpha-1-antitrypsin gene into the ROSA26 "safe harbor" locus in murine livers, using CRISPR/Cas9. We found adenoviral-mediated delivery of CRISPR/Cas9 achieved gene editing outcomes persisting over 200 days. Furthermore, gene knock-in maintained greater levels of the serum protein than provided by episomal expression. Importantly, our "knock-in" approach is generalizable to other serum proteins and supports in vivo cDNA replacement therapy to achieve stable gene expression.

Abstract
Malaria remains a considerable burden on public health. In 2015, the WHO estimates there were 212 million malaria cases causing nearly 429,000 deaths globally. A highly effective malaria vaccine is needed to reduce the burden of this disease. We have developed an experimental vaccine candidate (PyCMP) based on pre-erythrocytic (CSP) and erythrocytic (MSP1) stage antigens derived from the rodent malaria parasite P. yoelii. Our protein-based vaccine construct induces protective antibodies and CD4+ T cell responses. Based on evidence that viral vectors increase CD8+ T cell-mediated immunity, we also have tested heterologous prime-boost immunization regimens that included human adenovirus serotype 5 vector (Ad5), obtaining protective CD8+ T cell responses. While Ad5 is commonly used for vaccine studies, the high prevalence of pre-existing immunity to Ad5 severely compromises its utility. Here, we report the use of the novel simian adenovirus 36 (SAd36) as a candidate for a vectored malaria vaccine since this virus is not known to infect humans, and it is not neutralized by anti-Ad5 antibodies. Our study shows that the recombinant SAd36PyCMP can enhance specific CD8+ T cell response and elicit similar antibody titers when compared to an immunization regimen including the recombinant Ad5PyCMP. The robust immune responses induced by SAd36PyCMP are translated into a lower parasite load following P. yoelii infectious challenge when compared to mice immunized with Ad5PyCMP.

Abstract
PURPOSE To demonstrate that non-invasive bioluminescent imaging can monitor restricted expression from a nonreplicating adenovirus in which the cyclooxygenase-2 (COX-2) promoter drives firefly luciferase. PROCEDURES Adenovirus in which the COX-2 promoter drives the firefly luciferase imaging gene was injected intratumorally into xenografts that express relatively low and relatively high levels of COX-2. Adenovirus that expresses Renilla Luciferase from the cytomegalovirus early promoter was co-injected, to normalize for injection, leakage, vascularization, etc. COX-2 restricted firefly luciferase and global Renilla Luciferase activities were measured by optical imaging techniques both in vivo and in isolated tissues. RESULTS Dramatic reduction in hepatic luciferase expression after intravenous viral injection can be imaged non-invasively in living animals. Following intratumoral injection, luciferase levels in tumor xenografts that express differing endogenous COX-2 levels reflect the luciferase levels observed when these cells are infected in cell culture. Essentially no luciferase expression is observed in liver following intratumoral injection. CONCLUSION Both tissue restricted expression and transcriptional redirection to tumors expressing COX-2 can be imaged non-invasively following injection of Adenovirus expressing firefly luciferase from the COX-2 promoter.

Abstract
Adenovirus type 5 (Ad5) is one of the most promising vectors for gene therapy applications. Genetic engineering of Ad5 capsid proteins has been employed to redirect vector tropism, to enhance infectivity, or to circumvent preexisting host immunity. As the most abundant capsid protein, hexon modification is particularly attractive. However, genetic modification of hexon often results in failure of rescuing viable viruses. Since hypervariable regions (HVRs) are nonconserved among hexons of different serotypes, we investigated whether the HVRs could be used for genetic modification of hexon by incorporating oligonucleotides encoding six histidine residues (His6) into different HVRs in the Ad5 genome. The modified viruses were successfully rescued, and the yields of viral production were similar to that of unmodified Ad5. A thermostability assay suggested the modified viruses were stable. The His6 epitopes were expressed in all modified hexon proteins as assessed by Western blotting assay, although the intensity of the reactive bands varied. In addition, we examined the binding activity of anti-His tag antibody to the intact virions with the enzyme-linked immunosorbent assay and found the His6 epitopes incorporated in HVR2 and HVR5 could bind to anti-His tag antibody. This suggested the His6 epitopes in HVR2 and HVR5 were exposed on virion surfaces. Finally, we examined the infectivities of the modified Ad vectors. The His6 epitopes did not affect the native infectivity of Ad5 vectors. In addition, the His6 epitopes did not appear to mediate His6-dependent viral infection, as assessed in two His6 artificial receptor systems. Our study provided valuable information for studies involving hexon modification.

Abstract
Ovarian carcinoma cells are often infected inefficiently by adenoviruses (Ad) due to low expression of coxsackie-adenovirus receptors (CAR), hindering the application of adenovirus-mediated gene therapy in ovarian cancer. In this study, we explored a class of infectivity-enhanced Ad vectors, which contain CAR-independent targeting motifs RGD (Ad5.RGD), polylysine (Ad5.pK7), or both (Ad5.RGD.pK7), for their utility in ovarian cancer gene therapy using in vitro and in vivo model systems. We found that these vectors infected established ovarian carcinoma cell lines and primary ovarian cancer cells with significantly enhanced infectivity. Among them, Ad5.RGD.pK7 appeared to be most efficient. Further, we evaluated their gene delivery efficiency using two different ovarian cancer mouse models--subcutaneous and intraperitoneal human ovarian cancer xenografts. All of the modified vectors appeared to be more efficient than the unmodified Ad5 vector in both models, although some of the differences are not statistically significant. Of these, Ad5.RGD.pK7 exhibited the highest efficacy in the subcutaneous tumor model, while Ad5.pK7 worked most efficiently in the intraperitoneal tumor model. These preclinical results suggest that Ad5.RGD.pK7 and Ad5.pK7 may be very useful in ovarian cancer gene therapy.

Abstract
As an initial assessment of the feasibility of employing the adenovirus serotype 3 (Ad3) fiber knob as a locale for introducing a tropism-modifying motif, we generated an adenoviral vector containing a six-histidine tag genetically fused to the carboxy-terminus of the Ad3 fiber knob. The heterologous tag proved to be accessible for binding in the context of the virion and, moreover, had rendered the modified vector capable of mediating gene transfer through an artificial, non-Ad3 receptor.

Abstract
Adenovirus serotype 5 (Ad5) has great potential for gene therapy applications. A major limitation, however, is the host immune response against Ad5 infection that often prevents the readministration of Ad5 vectors. In this regard, the most abundant capsid protein, hexon, has been implicated as the major target for neutralizing antibodies. In this study, we sought to escape the host neutralization response against Ad5 via hexon replacement. We constructed a chimeric adenovirus vector, Ad5/H3, by replacing the Ad5 hexon gene with the hexon gene of Ad3. The chimeric viruses were successfully rescued in 293 cells. Compared to that for the control Ad5/H5, the growth rate of Ad5/H3 was significantly slower and the final yield was about 1 log order less. These data indicate that the Ad3 hexon can encapsidate the Ad5 genome, but with less efficiency than the Ad5 hexon. The gene transfer efficacy of Ad5/H3 in HeLa cells was also lower than that of Ad5/H5. Furthermore, we tested the host neutralization responses against the two viruses by using C57BL/6 mice. The neutralizing antibodies against Ad5/H3 and Ad5/H5 generated by the immunized mice did not cross-neutralize each other in the context of in vitro infection of HeLa cells. Preimmunization of C57BL/6 mice with one of the two types of viruses also did not prevent subsequent infection of the other type. These data suggest that replacing the Ad5 hexon with the Ad3 hexon can circumvent the host neutralization response to Ad5. This strategy may therefore be used to achieve the repeated administration of Ad5 in gene therapy applications.

Abstract
Production of large quantities of recombinant adeno-associated virus (AAV) is difficult and not cost-effective. To overcome this problem, we have explored the feasibility of creating a recombinant AAV encoding a 6xHis tag on the VP3 capsid protein. We generated a plasmid vector containing a six-His (6xHis)-tagged AAV VP3. A second plasmid vector was generated that contained the full-length AAV capsid capable of producing VP1 and VP2, but not VP3 due to a mutation at position 2809 that encodes the start codon for VP3. These plasmids, necessary for production of AAV, were transfected into 293 cells to generate a 6xHis-tagged VP3mutant recombinant AAV. The 6xHis-tagged VP3 did not affect the formation of AAV virus, and the physical properties of the 6xHis-modified AAV were equivalent to those of wild-type particles. The 6xHis-tagged AAV did not affect the production titer of recombinant AAV and could be used to purify the recombinant AAV using an Ni-nitrilotriacetic acid column. Addition of the 6xHis tag did not alter the viral tropism compared to wild-type AAV. These observations demonstrate the feasibility of producing high-titer AAV containing a 6xHis-tagged AAV VP3 capsid protein and to utilize the 6xHis-tagged VP3 capsid to achieve high-affinity purification of this recombinant AAV.

Abstract
Adenoviral vectors based on serotype 5 (Ad5) have been widely used to deliver therapeutic genes to different organs and tissues. However, many tissues are poorly infected with Ad5 because of low-level expression of its primary receptor, coxsackievirus-adenovirus receptor (CAR). Two motifs, RGD and polylysine (pK7), have been shown to enhance Ad5 infection via CAR-independent pathways when incorporated into fiber separately. Because the two motifs bind to different cell surface proteins (RGD motif binds to integrins, and pK7 binds to heparan sulfate-containing receptors), we hypothesized that the two motifs function additively to improve gene transfer efficiency. In this study, we sought to improve infectivity of Ad5 by incorporating both RGD and pK7 motifs into fiber. We created an Ad5 vector containing an RGD motif in the HI loop and a pK7 motif at the C terminus of fiber (Ad5.RGD.pK7). Compared with unmodified and singly modified Ad5 vectors Ad5.RGD and Ad5.pK7, the doubly modified Ad5 demonstrated the highest infectivity in both CAR-positive and CAR-negative cells. The enhanced infectivity appeared to be mediated by additive effects of the two motifs. More importantly, Ad5.RGD.pK7 lost the natural CAR-dependent pathway while employing novel targeting mechanisms. This strategy thus may be used to overcome CAR deficiency and to achieve vector retargeting.

Abstract
Recent studies demonstrate that the fiber shaft length, which ranges from six beta-repeats to 23 beta-repeats in human adenoviruses (Ads), influences viral tropism. We have previously shown that artificial extension of the shaft length inhibits infectivity in CAR (coxsackievirus and Ad receptor)-positive cell lines, but does not affect infectivity in a CAR-independent, integrin-dependent cell entry pathway. On the basis of these findings, we hypothesized that Ad vectors with shaft extension might display lower infectivity in liver, which expresses high levels of CAR. We also postulated that infectivity of Ad vectors with shaft extension in CAR-negative tumors could be increased by exploiting a CAR-independent cell entry by incorporation of an RGD4C motif into the fiber knob HI-loop. We thus compared gene transfer efficiencies of our Ad serotype 5 (Ad5) capsid-based 'longer-shafted' Ad vector with or without an RGD4C motif in the HI-loop of the fiber knob (Ad5long and Ad5RGDlong, 32 beta-repeats) to wild-type Ad vector (Ad5, 22 beta-repeats) in vitro and in vivo. In this study, Ad5long showed similar infectivity in CAR-negative tumors (69.7%, P = 0.098), but significantly reduced infectivity in CAR-positive tumors (19.1%, P = 0.000038) and in liver (12.5%, P = 0.0047) compared with Ad5. On the other hand, Ad5RGDlong demonstrated similar infectivity in CAR-positive tumors (70.5%, P = 0.012) and in liver (83.4%, P = 0.51), but significantly increased infectivity in CAR-negative tumors (327%, P = 0.0000042) compared with Ad5. Importantly, Ad5RGDlong demonstrated an augmented gene transfer capacity for CAR negative tumors, but no enhanced hepatotropism in vivo. We suggest that Ad vectors with artificial fiber shaft extension in combination with HI loop ligands may be useful for gene therapy applications.

Abstract
Recent studies demonstrate that virus-cellular receptor interactions are not the sole determinants of adenovirus (Ad) tropism. It has been shown that the fiber shaft length, which ranges from 6 to 23 beta-repeats in human Ads, also influences viral tropism. However, there is no report that investigates whether artificial extension of the shaft alters the infectivity profile of Ad. Therefore, we constructed Ad serotype 5 (Ad5) capsid-based longer-shafted Ad vectors by incorporating Ad2 shaft fragments of different lengths into the Ad5 shaft. We show that "longer-shafted" Ad vectors (up to 32 beta-repeats) could be rescued. We also show that longer-shafted Ad vectors had no impact on knob-CAR (coxsackievirus and Ad receptor) interaction compared to wild-type Ad. Nevertheless, gene transfer efficiencies of longer-shafted Ad vectors were lower in CAR-positive cell lines compared to wild-type Ad. We suggest that artificial extension of the shaft can inhibit infectivity in the context of CAR-positive cell lines without modification of knob-CAR interaction.

Abstract
Adenoviral (Ad) vectors have been widely used in the context of cancer gene therapy approaches. Their utility in these contexts, however, has frequently been limited by tumor cell resistance to Ad infection. The basis of this resistance has been defined recently as resulting from a deficiency of the primary adenovirus receptor, coxsackie adenovirus receptor. As a means to circumvent this limitation, a variety of tropism modification strategies have allowed coxsackie adenovirus receptor-independent gene delivery via the Ad vector. These advanced generation adenovirus vectors exhibit enhanced infectivity, which can allow direct therapeutic gain. Such vectors may allow improvements in efficacy in the context of ongoing human clinical gene therapy approaches for cancer.

Abstract
Human adenovirus (Ad) is extensively used for a variety of gene therapy applications. However, the utility of Ad vectors is limited due to the low efficiency of Ad-mediated gene transfer to target cells expressing marginal levels of the Ad fiber receptor. Therefore, the present generation of Ad vectors could potentially be improved by modification of Ad tropism to target the virus to specific organs and tissues. The fact that coxsackievirus and adenovirus receptor (CAR) does not play any role in virus internalization, but functions merely as the virus attachment site, suggests that the extracellular part of CAR might be utilized to block the receptor recognition site on the Ad fiber knob domain. We proposed to design bispecific fusion proteins formed by a recombinant soluble form of truncated CAR (sCAR) and a targeting ligand. In this study, we derived sCAR genetically fused with human epidermal growth factor (EGF) and investigated its ability to target Ad infection to the EGF receptor (EGFR) overexpressed on cancer cell lines. We have demonstrated that sCAR-EGF protein is capable of binding to Ad virions and directing them to EGFR, thereby achieving targeted delivery of reporter gene. These results show that sCAR-EGF protein possesses the ability to effectively retarget Ad via a non-CAR pathway, with enhancement of gene transfer efficiency.

Abstract
Recombinant adenoviruses (Ad) have become the vector system of choice for a variety of gene therapy applications. However, the utility of Ad vectors is limited due to the low efficiency of Ad-mediated gene transfer to cells expressing marginal levels of the coxsackievirus and adenovirus receptor (CAR). In order to achieve CAR-independent gene transfer by Ad vectors in clinically important contexts, we proposed modification of viral tropism via genetic alterations to the viral fiber protein. We have shown that incorporation of an Arg-Gly-Asp (RGD)-containing peptide in the HI loop of the fiber knob domain results in the ability of the virus to utilize an alternative receptor during the cell entry process. We have also demonstrated that due to its expanded tissue tropism, this novel vector is capable of efficient transduction of primary tumor cells. An increase in gene transfer to ovarian cancer cells of 2 to 3 orders of magnitude was demonstrated by the vector, suggesting that recombinant Ad containing fibers with an incorporated RGD peptide may be of great utility for treatment of neoplasms characterized by deficiency of the primary Ad type 5 receptor.
