Book excerpt: Abstract: Human T-cell leukemia virus type 1 (HTLV-1) is a pathogenic retrovirus that has the capacity to transform primary human T-lymphocytes in culture and infected individuals. After nearly 30 years of research, the exact mechanism by which HTLV-1 induces cellular transformation and ultimately disease still remains elusive. Tax has been identified as the major viral determinant and is essential to the HTLV-1-mediated T-cell transformation process. The HTLV-1 accessory proteins p12, p13, and p30 are dispensable in culture, but are required for the maintenance of viral loads in vivo. In this dissertation, we sought to broaden our knowledge of HTLV-1 using in vitro culture assays and two animal model approaches focusing our efforts on understanding the contribution of a novel antisense encoded gene, the HTLV-1 basic leucine zipper factor (Hbz), in virus biology. Chapter 1 reviewed important aspects of HTLV-1 pathobiology and highlighted insightful comparative studies between HTLV-1 and HTLV-2. Our work in Chapter 2 determined that the HBZ protein is dispensable for immortalization/transformation of T-lymphocytes in culture, but is required for efficient infectivity and persistence in inoculated rabbits. In Chapter 3, utilizing Hbz-specific short hairpin RNA lentiviral vectors, we showed that Hbz significantly contributed to tumor formation and neoplastic cell spread in the NOG mouse transplant model. Chapter 4 expanded on Chapter 3 to show that Hbz functions in two molecular forms, mRNA and protein, to synergistically increase cell proliferation in vitro. Collectively our results indicate that the Hbz gene negativly regulates Tax-mediated viral gene expression and dysrupts the cellular microenviroment to ultimately support virus survival. The data in this dissertation have allowed us to better understand the contribution of Hbz to HTLV-1 infection, and its involvement in the development of disease.

Download or read book Comparative studies between HTLV 1 and HTLV 2 function and pathobiology written by Umberto Bertazzoni and published by Frontiers Media SA. This book was released on 2015-06-11 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human T-cell leukemia viruses type 1 and 2 (HTLV-1 and HTLV-2) share a common genetic organization, expression strategy and ability to infect and immortalize T-cells in vitro; however, HTLV-1 and HTLV-2 are strikingly different in terms of clinical impact. HTLV-1 is recognized as the aetiological agent of adult T-cell leukemia/lymphoma (ATLL), and HTLV-associated myeolopathy/tropical spastic paraparesis (HAM/TSP), in contrast, HTLV-2 does not cause hematologic disorders and is only sporadically associated with cases of subacute myelopathy. HTLV-1 and HTLV-2 also exhibit distinct cellular tropisms in vivo: HTLV-1 is mainly found in CD4+T lymphocytes, whereas CD8+T-cells are the preferred target for HTLV-2. The articles contributed in this Research Topic are covering all the different aspects that characterize HTLV-1 and HTLV-2, by highlighting differences in their biology that might provide clues to their distinct pathogenic properties.

Download or read book Genetic Susceptibility to Infectious Diseases written by Richard A. Kaslow M.D. and published by Oxford University Press. This book was released on 2008-03-03 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infectious diseases are commonly regarded as a distinct category, with different causes and patterns than chronic or genetic disease. But in fact there are many varieties of genetic susceptibility to infection, the subject of this book, which will be divided into three sections: 1) concepts and methods, 2) genes and pathophysiologic mechanisms, and 3) infectious agents and diseases. No currently plubished text on either genetics or infectious diseases focuses on the genetic aspects of the special relationship between host and pathogen in the way envisioned for Section 1. No other work on the selected genes regulating immunity deals as systematically with the sequence variation/function relationships most pertinent to infection as planned for Section 2. And no other book gives as meaningful a picture of how these genes operate in infectious disease as Section 3 will.

Virology, virus-induced inflammation and tissue injuries, oncogenic mechanisms, epidemiology, and current and emerging preventive and therapeutic strategies are all discussed in detail. In addition, the book covers the individual aspects of seven oncogenic viruses, i.e., hepatitis B virus, hepatitis C virus, human papilloma virus, Epstein-Barr virus, human T-cell lymphotropic virus, Kaposi sarcoma-associated herpes virus, and Merkel cell polyomavirus, and the related human cancers.
Download or read book Discovering Retroviruses written by Anna Marie Skalka and published by Harvard University Press. This book was released on 2018-10-15 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately eight percent of our DNA contains retroviral sequences that are millions of years old. Through engaging stories of scientific discovery, Anna Marie Skalka explains our evolving knowledge of these ancient denizens of the biosphere and how this understanding has significantly advanced research in genetic engineering, gene delivery systems, and precision medicine. Discovering Retroviruses begins with the pioneer scientists who first encountered these RNA-containing viruses and solved the mystery of their reproduction. Like other viruses, retroviruses invade the cells of a host organism to reproduce. What makes them “retro” is a unique process of genetic information transfer. Instead of transcribing DNA into RNA as all living cells do, they transcribe their RNA into DNA. This viral DNA is then spliced into the host’s genome, where the cell’s synthetic machinery is co-opted to make new virus particles. The 100,000 pieces of retroviral DNA in the human genome are remnants from multiple invasions of our ancestors’ “germline” cells—the cells that allow a host organism to reproduce. Most of these bits of retroviral DNA are degenerated fossils, but some have been exploited during evolution, with profound effects on our physiology. Some present-day circulating retroviruses cause cancers in humans and other animals. Others, like HIV, cause severe immunodeficiencies. But retroviruses also hold clues to innovative approaches that can prevent and treat these diseases. In laboratories around the world, retroviruses continue to shed light on future possibilities that are anything but “retro.”
Download or read book Transacting Functions of Human Retroviruses written by Irvin S.Y. Chen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The coding domains of simple retrovirus genomes direct the synthesis of virion proteins. Complex retroviral genomes generate in addition to virion proteins regulatory transacting proteins that are translated from multiple spliced messenger RNAs and fulfill important functions in the virus life cycle. All human retroviruses have such complex genomes. The transacting proteins of these pathogens are attractive targets for therapeutic intervention because they are viral specific, are essential for efficient virus replication and may be mediators of viral pathogenicity. In summarizing the current knowledge on the regulatory transacting proteins of human retroviruses this volume makes an important contribution toward the control of virus disease.

This book was released on 2020 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human T-cell leukemia virus type 1 (HTLV-1) is deltaretrovirus with an estimated 5-10 million individuals infected worldwide. HTLV-1 is the etiologic agent of a non- Hodgkin’s peripheral T-cell malignancy called adult T-cell leukemia/lymphoma (ATL) and a demyelinating lymphocytic meningomyelitis termed HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Approximately 10% of infected individuals will develop ATL or HAM/TSP and there are limited treatment options. Examining the viral and cellular determinants that modulate early infection is vital to our understanding HTLV-1 pathobiology. Recently a binding site for the multifunctional DNA-binding protein CTCF was identified at a sharp border of epigenetic modification within the HTLV-1 provirus.
