| Abstract | Oncoviridae regroup several related retroviruses such as Human T-cell lymphotropic viruses (HTLV), Simian T cell lymphotropic viruses (STLV), and Bovine leukemia virus (BLV). Here we present an overview on different animal models used in the study of these viruses. These models vary from naturally infected animals to established, engineered or xenograft models. A special attention will be given to the HTLV-1 virus, the causative agent of adult T-cell leukemia/lymphoma (ATL) and a number of inflammatory diseases such as the HTLV-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Monkeys, rabbits and rats provide an excellent in vivo tool for the study of early viral infection and transmission as well as the antiviral host immune response. However, because of their small size and the availability of reagents, mice remain the most efficient method of studying human afflictions. Murine models regroup genetically altered mice including both transgenic and knock-out mice, as well as immunodeficient mice strains. The first group offers important models to test the role of specific viral and host genes in the development of HTLV-I associated leukemia whereas the second group provides a useful and rapid tool of humanized and xenografted mice models. These later are widely used to test new drugs and targeted therapy against HTLV-1 associated leukemia, to identify potential leukemia stem cells, and to study the innate immunity against the virus. Altogether, these animal models have revolutionized the biology of retroviruses, their manipulation of host genes and more importantly the potential ways to either prevent their infection or to treat their associated diseases. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
