Abstract
Adenoviruses represent exceptional candidates for wide-ranging therapeutic applications, from vectors for gene therapy to oncolytics for cancer treatments. The first ever commercial gene therapy medicine was based on a recombinant adenovirus vector, while most recently, adenoviral vectors have proven critical as vaccine platforms in effectively controlling the global coronavirus pandemic. Here, we discuss factors involved in adenovirus cell binding, entry, and trafficking; how they influence efficiency of adenovirus-based vectors; and how they can be manipulated to enhance efficacy of genetically modified adenoviral variants. We focus particularly on endocytosis and how different adenovirus serotypes employ different endocytic pathways to gain cell entry, and thus, have different intracellular trafficking pathways that subsequently trigger different host antiviral responses. In the context of gene therapy, the final goal of the adenovirus vector is to efficiently deliver therapeutic transgenes into the target cell nucleus, thus allowing its functional expression. Aberrant or inefficient endocytosis can impede this goal, therefore, it should be considered when designing and constructing adenovirus-based vectors.

Abstract
Significant progress has been made in the diagnosis and treatment of cancer; however, significant challenges remain. Conditionally replicating adenoviruses (CRAds), which not only kill cancer cells, but also serve as vectors to express therapeutic genes, are a novel and effective method to treat cancer. However, most adenoviruses are Ad5, which infect cells through the coxsackie and adenovirus receptor (CAR). The transduction efficacy of Ad5 is restricted because of the absent or low expression of CAR on several cancer cells. Ad serotype 35 has a different tropism pattern to Ad5. Ad35 attaches to cells via a non-CAR receptor, CD46, which is expressed widely on most tumor cells. Thus, chimeric adenoviral vectors consisting of the knob and shaft of Ad35 combined with Ad5 have been constructed. The chimeric fiber adenoviral vectors can transduce CAR-positive and CAR-negative cell lines. In this review, we explore the application of the novel fiber chimeric conditionally replicative adenovirus-Ad5/F35 in tumor therapy in terms of safety, mechanism, transduction efficacy, and antitumor effect.

Abstract
The adenovirus death protein (ADP) is expressed at late times during a lytic infection of species C adenoviruses. ADP promotes the release of progeny virus by accelerating the lysis and death of the host cell. Since some human lymphocytes survive while maintaining a persistent infection with species C adenovirus, we compared ADP expression in these cells with ADP expression in lymphocytes that proceed with a lytic infection. Levels of ADP were low in KE37 and BJAB cells, which support a persistent infection. In contrast, levels of ADP mRNA and protein were higher in Jurkat cells, which proceed with a lytic infection. Epithelial cells infected with an ADP-overexpressing virus died more quickly than epithelial cells infected with an ADP-deleted virus. However, KE37, and BJAB cells remained viable after infection with the ADP-overexpressing virus. Although the levels of ADP mRNA increased in KE37 and BJAB cells infected with the ADP-overexpressing virus, the fraction of cells with detectable ADP was unchanged, suggesting that the control of ADP expression differs between epithelial and lymphocytic cells. When infected with an ADP-deleted adenovirus, Jurkat cells survived and maintained viral DNA for greater than 1 month. These findings are consistent with the notion that the level of ADP expression determines whether lymphocytic cells proceed with a lytic or a persistent adenovirus infection.

Augmented adenovirus transduction of murine T lymphocytes utilizing a bi-specific protein targeting murine interleukin 2 receptor. Cancer Gene Ther 2013; 20:445-52.

Abstract
Adenoviruses are currently used in a variety of bench and bedside applications. However, their employment in gene delivery to lymphocyte lineages is hampered by the lack of coxsackie virus and adenovirus receptor (CAR) on the cell surface. Exploitation of an alternative receptor on the surface of T lymphocytes can allow for utilization of adenovirus in a variety of T lymphocyte-based diseases and therapies. Here, we describe how resistance to infection can be overcome by the utilization of a bi-specific fusion protein, soluble CAR murine interleukin 2 (sCAR-mIL-2), that retargets adenovirus to the murine IL-2 receptor (IL-2R). Infection of a murine T-cell line, CTLL-2, with a sCAR-mIL-2/Adenovirus conjugate provided a ninefold increase in both green fluorescence protein-positive cells and luciferase expression. In addition, this increase in infection was also seen in isolated primary murine T lymphocytes. In this context, the sCAR-mIL-2 adapter provided a fourfold gene transduction increase in activated primary murine T lymphocytes. Our results show that recombinant sCAR-mIL-2 fusion protein promotes IL-2R-targeted gene transfer to murine T lymphocytes and that alternative targeting can abrogate their native resistance to infection.

Abstract
Species C adenovirus establishes a latent infection in lymphocytes of the tonsils and adenoids. To understand how this lytic virus is maintained in these cells, four human lymphocytic cell lines that support the entire virus life cycle were examined. The T-cell line Jurkat ceased proliferation and died shortly after virus infection. BJAB, Ramos (B cells), and KE37 (T cells) continued to divide at nearly normal rates while replicating the virus genome. Viral genome numbers peaked and then declined in BJAB cells below one genome per cell at 130 to 150 days postinfection. Ramos and KE37 cells maintained the virus genome at over 100 copies per cell over a comparable period of time. BJAB cells maintained the viral DNA as a monomeric episome. All three persistently infected cells lost expression of the cell surface coxsackie and adenovirus receptor (CAR) within 24 h postinfection, and CAR expression remained low for at least 340 days postinfection. CAR loss proceeded via a two-stage process. First, an initial loss of cell surface staining for CAR required virus late gene expression and a CAR-binding fiber protein even while CAR protein and mRNA levels remained high. Second, CAR mRNA disappeared at around 30 days postinfection and remained low even after virus DNA was lost from the cells. At late times postinfection (day 180), BJAB cells could not be reinfected with adenovirus, even when CAR was reintroduced to the cells via retroviral transduction, suggesting that the expression of multiple genes had been stably altered in these cells following infection.

Abstract
Human adenoviruses (HAdV) are widely used for in vitro and in vivo gene transfer. Viral hepatotropism, inflammatory responses and neutralization by pre-existing antibodies (NAbs) are obstacles for clinical applications of HAdV vectors. Although the multifactorial events leading to innate HAdV toxicity are far from being elucidated, there is a consensus that the majority of intravenously injected-HAdV vectors is sequestered by Kuppfer cells, probably independently of coagulation factors. In this study, we show that the adenoviral-associated humoral and innate cytokine immune responses are significantly reduced when HAdV-5 vector carrying human bovine chimeric fibers (HAdV-5-F2/BAdV-4) is intravenously injected into mice. Fiber pseudotyping modified its interaction with blood coagulation factors, as FIX and FX no longer mediate the infection of liver cells by HAdV-5-F2/BAdV-4. As a consequence, at early time points post-infection, several cytokines and chemokines (IFN-gamma, IL-6, IP-10, MCP-1, RANTES and MP1beta) were found to be present at lower levels in the plasma of mice that had been intravenously injected with HAdV-5-F2/BAdV-4 compared with mice injected with the parental vector HAdV-5. Moreover, genetic modification of the fiber allowed HAdV-5-F2/BAdV-4 to partially escape neutralization by NAbs.

Abstract
Gene transfer applications with adenovirus (Ad) type 5 are limited by its native tropism, hampering their use in several cell types. To address this limitation, several Ad vectors bearing chimeric fiber have been produced to take advantage of the different cellular receptors used by other subgroups of Ads. In this study, we have compared the transduction efficiency of Ad5 and the chimeric Ad5/F35 in primary human B lymphocytes and B-cell lines as a function of the developmental stage. We found that transduction efficiencies of the two Ads differ independently of their targeted cellular receptor but are related to the intracellular localization of the virus. In efficiently transduced cells, Ads were localized in early endosomes or cytosol, whereas in poorly transduced cells they were localized within late endosomes/lysosomes. Finally, we demonstrate that treatment of cells with phosphatase inhibitors known to redirect endocytosis towards caveolae, increased Ad5/F35 transduction efficiency.

Abstract
Most adenoviral vectors (HAdvs) elaborated for gene therapy are derived from serotype 5 viruses that use clathrin-coated vesicle endocytosis for cell entry. However, it appears that adenoviral vectors are able to take advantage of lipid raft/caveolae endocytosis to infect cells. In vivo targeting of a therapeutic gene to specific cells by vector engineering has become a major focus of gene therapy research. Yet, modification of adenoviral tropism, especially fiber gene engineering, can induce deficient intracellular trafficking of the viral particle, with a shift in subcellular localization resulting in extensive exocytosis. In this study we demonstrate that uptake of a fiber-modified adenovirus using lipid raft/caveolae endocytosis leads to non-altered intracellular trafficking without endosomal retention. Moreover, activation of lipid raft structures by this vector leads to the formation of "mega-caveosomes". These results demonstrate that, by forcing adenoviruses to take advantage of a non-clathrin, non-classical endocytic pathway, it is possible to compensate for the deficiency in endosomolysis that is associated with the use of some of the fiber-modified adenoviral constructs. Moreover, it renders such vectors ideal candidates for infecting human coxsackie and adenoviruses receptor (hCAR) negative cells.

Abstract
Gene transfer by adenoviruses, which are widely used for gene therapy, may provide an alternative approach to treatment of several hematopoietic malignancies. However, a major limitation of adenovirus 5-based gene therapy lies in the natural tropism of the virus for the widely expressed hCAR receptor. The efficacy of adenoviral vectors could be improved if viral vectors that exhibit tissue-specific gene delivery were developed. For efficient gene transfer it is essential that every step from binding of virus to target cells to transgene expression is successfully accomplished. We developed a specific vector targeting the CD21 receptor, by inserting a CD21 binding sequence, derived from the EBV GP350/220 protein, into the HI loop of the HAdV5 fiber protein. This vector, HAdV5-CD21HIloop, binds specifically to CD21-positive cells and results in enhanced expression of the transgene in these cells and reduced expression in CD21-negative cells. Viral infection is highly correlated with the presence of CD21 receptors. Taken together, these results demonstrate that HAdV5-CD21HIloop is able to transduce CD21-positive cells specifically with reduced infection of nontarget cells. This is the result of the maintenance of the intracellular trafficking of the genetically modified adenovirus without vesicular retention, leading to enhanced nuclear transfer.

Abstract
Hematopoietic cells are attractive targets for gene therapy, but the conventional adenovirus (Ad) vectors, based on Ad5, transduce these cells inefficiently. One reason for low permissiveness of hematopoietic cells to infection by species C Ads appears to be inefficient attachment. Vectors pseudotyped with species B fibers are clearly more efficient at transducing hematopoietic cells than Ad5. To evaluate which Ad species B type(s) would be the most efficient vector(s) for primary T-cells, B-cells and monocytes, attachment to and entry of the species B1 serotypes 3p and 7p and the species B2 serotypes 11p and 35 into primary PBMCs was studied. Ad11p and Ad35 were the only serotypes to show efficient binding and for which uptake by PBMCs could be detected. Infection of PBMCs by Ad5, Ad11p and Ad35 was compared. Expression of Ad hexons was detected in stimulated PBMCs, most frequently in T-cells, and in unstimulated monocytes, although B-cells appear to be refractory to productive infection. Replication of Ad DNA was severely restricted in most PBMCs. Neither hexon expression nor genome replication could be detected in unstimulated lymphocytes, but FISH and a real-time PCR-based assay suggested that Ad11p and Ad35 DNA reach the nucleus. Activation thus appears to be required for T-cells to be permissive to Ad gene expression. In summary, there are substantial differences between Ad3p and Ad7p on the one hand and Ad11p and Ad35 on the other, in their ability to interact with PBMCs. Ad11p and Ad35 probably represent vectors of choice for these cell types.

PURPOSE Polo-like kinase 1 (plk1) is a serine/threonine protein kinase essential for multiple mitotic processes. Previous observations have validated plk1 as a promising therapeutic target. Despite being conceptually attractive, the potency and specificity of current plk1-based therapies remain limited. We sought to develop a novel plk1-targeting strategy by constructing an oncolytic adenovirus to selectively silence plk1 in tumor cells. EXPERIMENTAL DESIGN Two artificial features were engineered into one wild-type adenovirus type 5 (wt-Adv5) genome to generate a new oncolytic adenovirus (M1). First, M1 contains a 27-bp deletion in E1A region, which confers potent, oncolytic efficacy. Second, M1 is armed with a fragment of antisense plk1 cDNA that substitutes the E3 region encoding 6.7K and gp19K. In this design, tumor-selective replication of M1 would activate the native adenovirus E3 promoters to express the antisense plk1 cDNA preferentially in tumor cells and silence tumor-associated plk1 protein. RESULTS By virtue of combining oncolysis with plk1 targeting, M1 exhibited potent antitumoral efficacy in vitro and in vivo. Systemic administration of M1 plus cisplatin induced complete tumor regression in 80% of orthotopic hepatic carcinoma model mice that were otherwise resistant to cisplatin and disseminated metastases. CONCLUSIONS Coupling plk1 targeting with oncolysis had shown superior antitumor efficacy. Present findings would benefit the development of novel oncolytic adenoviruses generally applicable to a wide range of molecule-based therapeutics.

Abstract
Hematopoietic cells are known to be refractory to species C human adenovirus (HAdV) infection; however, the reason for this has not been clearly established. We have previously demonstrated that this nonpermissivity is the consequence of inefficient HAdV particle uptake, notably in B lymphocytes. We noted that while the protein clathrin is observed in association with membranes in epithelial cells, it is found predominantly in the cytoplasm of hematopoietic cell lines. So it appears that altered clathrin-coated pit endocytosis could explain the weak HAdV uptake in B cells. In contrast, mature B cell plasmocytes are permissive to HAdV. However, this is not the result of clathrin-coated pit endocytosis since this process is also inefficient in these cells. Confocal microscopy showed colocalization between HAdV particles and caveolae/lipid rafts in plasmocytes. Moreover, inhibiting caveola endocytosis by depletion of cholesterol or expression of dominant negative caveolin-1 in these cells results in a 50-70% reduction in HAdV infectivity. It appears that caveola endocytosis and nonclathrin noncaveola endocytosis are used by HAdV to enter plasmocytes in response to a loss of the clathrin-dependent pathway. Thus targeting of caveolae by modifying the capsid of HAdV may represent an alternative approach to enhancing uptake in most hematopoietic cells for future gene therapy.
