Targeted delivery of vaccine candidates to the gastrointestinal (GI) tract holds potential for mucosal immunization, particularly against mucosal pathogens like the human immunodeficiency virus (HIV). Among the different strategies for achieving targeted release in the GI tract, namely the small intestine, pH sensitive enteric coating polymers have been shown to protect solid oral dosage forms from the harsh digestive environment of the stomach and dissolve relatively rapidly in the small intestine by taking advantage of the luminal pH gradient. We developed an enteric polymethacrylate formulation for coating hydroxy-propyl-methyl-cellulose (HPMC) capsules containing lyophilized Adenoviral type 5 (Ad5) vectors expressing HIV-1 gag …

Direct Inhibition Of Cdk9 Blocks Hiv-1 Replication Without Preventing T Cell Activation In Primary Human Peripheral Blood Lymphocytes, Dominic Salerno, Muneer G Hasham, Renée Marshall Demarest, Judit Garriga, Alexander Y Tsygankov, Xavier Graña Dec 2007

Direct Inhibition Of Cdk9 Blocks Hiv-1 Replication Without Preventing T Cell Activation In Primary Human Peripheral Blood Lymphocytes, Dominic Salerno, Muneer G Hasham, Renée Marshall Demarest, Judit Garriga, Alexander Y Tsygankov, Xavier Graña

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

HIV-1 transcription is essential for the virus replication cycle. HIV-1 Tat is a viral transactivator that strongly stimulates the processivity of RNA polymerase II (RNAPII) via recruitment of the cyclin T1/CDK9 positive transcription elongation factor, which phosphorylates the C-terminal domain (CTD) of RNAPII. Consistently, HIV-1 replication in transformed cells is very sensitive to direct CDK9 inhibition. Thus, CDK9 could be a potential target for anti-HIV-1 therapy. A clearer understanding of the requirements for CDK9 activity in primary human T cells is needed to assess whether the CDK9-dependent step in HIV-1 transcription can be targeted clinically. We have investigated the effects …

Sheeppox virus (SPPV), a member of the Capripoxvirus genus of the Poxviridae, is the etiologic agent of a significant disease of sheep in the developing world. Genomic analysis of pathogenic and vaccine capripoxviruses identified genes with potential roles in virulence and host range, including three genes with similarity to kelch-like genes of other poxviruses and eukaryotes. Here, a mutant SPPV with a deletion in the SPPV-019 kelch-like gene, ΔKLP, was derived from the pathogenic strain SPPV-SA. ΔKLP exhibited in vitro growth characteristics similar to those of SPPV-SA and revertant virus (RvKLP). ΔKLP-infected cells exhibited a reduction in Ca2+ …

HIV-1 subtype C is the most common HIV-1 group M subtype in Africa and many parts of Asia. However, to date HIV-1 vaccine candidate immunogens have not induced potent and broadly neutralizing antibodies against subtype C primary isolates. We have used a centralized gene strategy to address HIV-1 diversity, and generated a group M consensus envelope gene with shortened consensus variable loops (CON-S) for comparative studies with wildtype (WT) Env immunogens. Our results indicate that the consensus HIV-1 group M CON-S Env elicited cross-subtype neutralizing antibodies of similar or greater breadth and titer than the WT Envs tested, indicating the …

The Distribution Of Sexually-Transmitted Human Papillomaviruses In Hiv Positive And Negative Patients In Zambia, Africa, Christopher Ngandwe, John Lowe, Paula J. Richards, Lara Hause, Charles Wood, Peter C. Angeletti Jul 2007

The Distribution Of Sexually-Transmitted Human Papillomaviruses In Hiv Positive And Negative Patients In Zambia, Africa, Christopher Ngandwe, John Lowe, Paula J. Richards, Lara Hause, Charles Wood, Peter C. Angeletti

Nebraska Center for Virology: Faculty Publications

Background: Human Papillomaviruses (HPV) are double-stranded DNA viruses, considered to be the primary etiological agents in cervical intraepithelial neoplasias and cancers. Approximately 15–20 of the 40 mucosal HPVs confer a high-risk of progression of lesions to invasive cancer. In this study, we investigated the prevalence of sexually transmitted HPVs in Human Immunodeficiency Virus (HIV) positive and negative patients in Zambia, Africa. The rate of high-risk HPV genotypes worldwide varies within each country. Thus, we sought to investigate the rates of HPV infection in sub-Saharan Africa and the potential role of HIV in affecting the HPV genotype distribution.

Chloroviruses Encode A Bifunctional Dcmp-Dctp Deaminase That Produces Two Key Intermediates In Dttp Formation, Yuanzheng Zhang, Frank Maley, Gladys F. Maley, Garry Duncan, David Dunigan, James L. Van Etten Jul 2007

Chloroviruses Encode A Bifunctional Dcmp-Dctp Deaminase That Produces Two Key Intermediates In Dttp Formation, Yuanzheng Zhang, Frank Maley, Gladys F. Maley, Garry Duncan, David Dunigan, James L. Van Etten

Nebraska Center for Virology: Faculty Publications

The chlorovirus PBCV-1, like many large double-stranded DNA-containing viruses, contains several genes that encode putative proteins involved in nucleotide biosynthesis. This report describes the characterization of the PBCV-1 dCMP deaminase, which produces dUMP, a key intermediate in the synthesis of dTTP. As predicted, the recombinant protein has dCMP deaminase activity that is activated by dCTP and inhibited by dTTP. Unexpectedly, however, the viral enzyme also has dCTP deaminase activity, producing dUTP. Typically, these two reactions are catalyzed by proteins in separate enzyme classes; to our knowledge, this is the first example of a protein having both deaminase activities. Kinetic experiments …

Detection Of Panulirus Argus Virus 1 In Caribbean Spiny Lobsters, Megan M. Montgomery-Fullerton, Roland Cooper, Kathryn M. Kauffman, Jeffrey D. Shields, Robert E. Ratzlaff Jun 2007

Detection Of Panulirus Argus Virus 1 In Caribbean Spiny Lobsters, Megan M. Montgomery-Fullerton, Roland Cooper, Kathryn M. Kauffman, Jeffrey D. Shields, Robert E. Ratzlaff

Collected Faculty and Staff Scholarship

Panulirus argus Virus 1 (PaV1) is a pathogenic virus that infects Caribbean spiny lobsters P. argus in the Florida Keys. We have developed a PCR detection assay for PaV1 for the purpose of studying the natural history of the virus and for monitoring the prevalence of infection. The detection of the virus in hemolymph and other tissues is based on the PCR amplification of a 499 bp product using specific primers designed from a cloned fragment of the PaV1 genome. The sensitivity limit for the assay was 1.2 fg of purified viral DNA. The PaV1 primers did not react with …

The Transcriptional Repressor K-Rbp Modulates Rta-Mediated Transactivation And Lytic Replication Of Kaposi’S Sarcoma-Associated Herpesvirus, Zhilong Yang, Charles Wood Jun 2007

The Transcriptional Repressor K-Rbp Modulates Rta-Mediated Transactivation And Lytic Replication Of Kaposi’S Sarcoma-Associated Herpesvirus, Zhilong Yang, Charles Wood

Nebraska Center for Virology: Faculty Publications

The replication and transcription activator (RTA) protein of Kaposi’s sarcoma (KS)-associated herpesvirus (KSHV)/human herpesvirus 8 functions as the key regulator to induce KSHV lytic replication from latency through activation of the lytic cascade of KSHV. Elucidation of the host factors involved in RTA-mediated transcriptional activation is pivotal for understanding the transition between viral latency and lytic replication. KSHV-RTA binding protein (K-RBP) was previously isolated as a cellular RTA binding protein of unknown function. Sequence analysis showed that K-RBP contains a Kruppel-associated box (KRAB) at the N terminus and 12 adjacent zinc finger motifs. In similarity to other KRAB-containing zinc finger …

Epstein-Barr Virus Inhibits Kaposi’S Sarcoma-Associated Herpesvirus Lytic Replication In Primary Effusion Lymphomas, Dongsheng Xu, Jun Zhang, Tricia Coleman, Ashley Fagot, Catherine Kotalik, Lingjun Zhao, Pankaj Trivedi, Clinton J. Jones, Luwen Zhang Jun 2007

Epstein-Barr Virus Inhibits Kaposi’S Sarcoma-Associated Herpesvirus Lytic Replication In Primary Effusion Lymphomas, Dongsheng Xu, Jun Zhang, Tricia Coleman, Ashley Fagot, Catherine Kotalik, Lingjun Zhao, Pankaj Trivedi, Clinton J. Jones, Luwen Zhang

Nebraska Center for Virology: Faculty Publications

The majority of AIDS-associated primary effusion lymphomas (PEL) are latently infected with both Kaposi’s sarcoma-associated herpesvirus (KSHV) and Epstein-Barr virus (EBV). PELs harboring two viruses have higher oncogenic potential, suggesting functional interactions between EBV and KSHV. The KSHV replication and transcription activator (K-RTA) is necessary and sufficient for induction of KSHV lytic replication. EBV latent membrane protein 1 (LMP-1) is essential for EBV transformation and establishment of latency in vitro. We show EBV inhibits chemically induced KSHV lytic replication, in part because of a regulatory loop in which K-RTA induces EBV LMP-1 and LMP-1 in turn inhibits K-RTA expression and …

The Nasal Cavity Is A Route For Prion Infection In Hamsters, Anthony E. Kincaid, Jason C. Bartz May 2007

The Nasal Cavity Is A Route For Prion Infection In Hamsters, Anthony E. Kincaid, Jason C. Bartz

Nebraska Center for Virology: Faculty Publications

Animals that naturally acquire the prion diseases have a well-developed olfactory sense that they utilize for a variety of basic behaviors. To assess the potential for the nasal cavity to serve as a point of entry for prion diseases, a small amount of prion-infected brain homogenate was placed inferior to the nostrils of hamsters, where it was immediately sniffed into the nasal cavity. Hamsters extranasally inoculated with the HY strain of transmissible mink encephalopathy (TME) agent had an incubation period that was not significantly different from per os inoculation of the same dose of the HY TME agent. However, the …

Protection Against Porcine Reproductive And Respiratory Syndrome Virus (Prrsv) Infection Through Passive Transfer Of Prrsv-Neutralizing Antibodies Is Dose Dependent, O. J. Lopez, M. F. Oliveira, E. Alvarez Garcia, Byung Joon Kwon, Alan R. Doster, Fernando A. Osorio Mar 2007

Protection Against Porcine Reproductive And Respiratory Syndrome Virus (Prrsv) Infection Through Passive Transfer Of Prrsv-Neutralizing Antibodies Is Dose Dependent, O. J. Lopez, M. F. Oliveira, E. Alvarez Garcia, Byung Joon Kwon, Alan R. Doster, Fernando A. Osorio

Nebraska Center for Virology: Faculty Publications

Previous work in our laboratory demonstrated that passive transfer of porcine reproductive and respiratory syndrome virus (PRRSV)-neutralizing antibodies (NA) protected pregnant sows against reproductive failure and conferred sterilizing immunity in sows and offspring. We report here on the dose requirement for protection by passive transfer with NA in young weaned pigs. The presence of a 1:8 titer of PRRSV-NA in serum consistently protected pigs against viremia. Nevertheless, their lungs, tonsils, buffy coat cells, and peripheral lymph nodes contained replicating PRRSV similar to the infected control group. Likewise, these animals excreted infectious virus to sentinels similar to the infectivity control animals. …

Human Immunodeficiency Virus Type 1 Pathobiology Studied In Humanized Balb/C-Rag2-/- ΓC-/- Mice, Santhi Gorantla, Hannah Seller, Lisa Walters, John G. Sharp, Samuel Pirruccello, John T. West, Charles Wood, Stephen Dewhurst, Howard Gendelman, Larisa Poluektova

Nebraska Center for Virology: Faculty Publications

The specificity of human immunodeficiency virus type 1 (HIV-1) for human cells precludes virus infection in most mammalian species and limits the utility of small animal models for studies of disease pathogenesis, therapy, and vaccine development. One way to overcome this limitation is by human cell xenotransplantation in immune-deficient mice. However, this has proved inadequate, as engraftment of human immune cells is limited (both functionally and quantitatively) following transplantation of mature human lymphocytes or fetal thymus/liver. To this end, a human immune system was generated from umbilical cord blood-derived CD34+ hematopoietic stem cells in BALB/c-Rag2-/- γc-/- …

Effects Of Turnip Crinkle Virus Infection On The Structure And Function Of Mitochondria And Expression Of Stress Proteins In Turnips, James A. Blake, Kit W. Lee, Thomas Jack Morris, Thomas Elthon Feb 2007

Effects Of Turnip Crinkle Virus Infection On The Structure And Function Of Mitochondria And Expression Of Stress Proteins In Turnips, James A. Blake, Kit W. Lee, Thomas Jack Morris, Thomas Elthon

Nebraska Center for Virology: Faculty Publications

We have investigated the effect of turnip crinkle virus (TCV) infection on mitochondrial structure and function in turnips (Brassica rapa cultivar “Just Right”). TCV infection resulted in plants with small, mottled leaves with severely crinkled edges, and in a 46% reduction in storage root mass. TCV infection resulted in specific vesicularization of mitochondrial outer membranes where TCV replication is thought to occur, with no apparent affect on other cellular membrane systems. Immunoblot analysis of mitochondrial proteins from storage roots indicated that the TCV p28 protein, which is essential for viral replication, was associated with mitochondria and that mitochondrial heat …

Novel Pathway For Induction Of Latent Virus From Resting Cd4+ T Cells In The Simian Immunodeficiency Virus/Macaque Model Of Human Immunodeficiency Virus Type 1 Latency, Anding Shen, Hung Chih Yang, Yan Zhou, Amanda J. Chase Feb 2007

Novel Pathway For Induction Of Latent Virus From Resting Cd4+ T Cells In The Simian Immunodeficiency Virus/Macaque Model Of Human Immunodeficiency Virus Type 1 Latency, Anding Shen, Hung Chih Yang, Yan Zhou, Amanda J. Chase

University Faculty Publications and Creative Works

Although combination therapy allows the suppression of human immunodeficiency virus type 1 (HIV-1) viremia to undetectable levels, eradication has not been achieved because the virus persists in cellular reservoirs, particularly the latent reservoir in resting CD4+ T lymphocytes. We previously established a simian immunodeficiency virus (SIV)/macaque model to study latency. We describe here a novel mechanism for the induction of SIV from latently infected resting CD4+ T cells. Several human cell lines including CEMx174 and Epstein-Barr virus-transformed human B-lymphoblastoid cell lines mediated contact-dependent activation of resting macaque T cells and induction of latent SIV. Antibody-blocking assays showed that interactions between …

Recovery from acute hepatitis B virus (HBV) infection requires a broad, vigorous T-cell response, which is enhanced in mice when chemokine receptor 5 (CCR5) is missing. To test the hypothesis that production of a nonfunctional CCR5 (CCR5Δ32 [a functionally null allele containing a 32-bp deletion]) increases the likelihood of recovery from hepatitis B in humans, we studied 526 persons from three cohorts in which one person with HBV persistence was matched to two persons who recovered from an HBV infection. Recovery or persistence was determined prior to availability of lamivudine. We determined genotypes forCCR5Δ32 …

Bird Movement Predicts Buggy Creek Virus Infection In Insect Vectors, Charles R. Brown, Mary Bomberger Brown, Amy T. Moore, Nicholas Komar Jan 2007

Bird Movement Predicts Buggy Creek Virus Infection In Insect Vectors, Charles R. Brown, Mary Bomberger Brown, Amy T. Moore, Nicholas Komar

School of Natural Resources: Faculty Publications

Predicting the spatial foci of zoonotic diseases is a major challenge for epidemiologists and disease ecologists. Migratory birds are often thought to be responsible for introducing some aviozoonotic pathogens such as West Nile and avian influenza viruses to a local area, but most information on how bird movement correlates with virus prevalence is anecdotal or indirect. We report that the prevalence of Buggy Creek virus (BCRV) infection in cimicid swallow bugs (Oeciacus vicarius), the principal invertebrate vector for this virus, was directly associated with the likelihood of movement by cliff swallows (Petrochelidon pyrrhonota), an amplifying host …

Buggy Creek virus (family Togaviridae, genus Alphavirus, BCRV) is an alphavirus within the western equine encephalitis virus complex whose primary vector is the swallow bug, Oeciacus vicarius Horvath (Hemiptera: Cimicidae), an ectoparasite of the colonially nesting cliff swallow, Petrochelidon pyrrhonota, that is also a frequent host for the virus.We investigated ecological correlates of BCRV infection in 100-bug pools at 14 different swallow colony sites in southwestern Nebraska from summer 2004, by using plaque assay on Vero cells to identify cytopathic virus and reverse transcription-polymerase chain reaction to identify noncytopathic viral RNA. We found 26.7% of swallow bug pools …

On A Multinational Assessment Of Rotavirus Disease In Europe, David O. Matson

Community & Environmental Health Faculty Publications

Rotaviruses were discovered in the 1960s in animals and in the 1970s in humans; the latter discovery was made by an intrepid group who performed duodenal biopsies on children with acute gastroenteritis (AGE) [1]. By the late 1970s, data already clearly indicated that rotavirus was the cause of the annual winter peak of AGE affecting young children, as well as a frequent cause of severe gastroenteritis in various animal species (e.g., [2–5]). Use of the retrospectroscope clarified or left as tantalizing the suggestion that rotaviruses were the cause of the annual “winter vomiting syndrome” first described in children in 1910 …
