| Abstract | Herpesvirus saimiri (HVS) has recently been shown to immortalize human CD4+ and CD8+ T cells expressing T-cell receptor alpha beta (TCR-alpha beta) with the maintenance of their original phenotypes and functional properties. However, the immortalization of human T cells expressing TCR-gamma delta by HVS has not been successful. Here we report that HVS can also infect and immortalize human T cells expressing TCR-gamma delta. Two human TCR-gamma delta+ T-cell clones, which continuously proliferated in interleukin-2-containing culture medium without any exogenous stimulation or addition of feeder cells for more than 8 months, were established by HVS infection. Morphologically, the HVS-transformed TCR-gamma delta+ T-cell clones were granular lymphocytes which exhibited wide-range HLA-unrestricted cytotoxicity as untransformed TCR-gamma delta+ T cells. Their phenotypes and cytotoxic activities were not altered during long-term culture. The immortalization of human TCR-gamma delta+ T cells by HVS infection would be useful for functional analysis of this lymphocyte population, which is believed to play an important role in protection against various infectious 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.
