| Abstract | Three different murine monoclonal antibodies to the human clonotypic T-cell antigen receptor immunoprecipitate the alpha-beta chain heterodimer; induce comodulation of the clonotypic molecule with the T3 molecular complex; stain small populations of normal polyclonal T cells, suggesting that they react with variable or joining region determinants of the clonotypic receptor; and induce proliferation of resting T cells. While two of these antibodies detect the clonotypic receptor in all individuals studied, the third antibody (OT145), described herein, does not detect the T-cell antigen receptor on T cells of all individuals. By indirect immunofluorescence, three groups can be distinguished within a population of individuals (n = 138) by OT145. Individuals lacking T cells reactive with OT145 have a homozygous OT145-phenotype. T cells from such individuals fail to proliferate in the presence of OT145 in contrast to T cells from OT145+ individuals. Individuals with a relatively large percentage of OT145+ T cells, 4.5 +/- 1.54% (mean +/- 2 SEM) are homozygous OT145+, while those with an intermediate percentage, 2.04 +/- 0.9%, have a heterozygous phenotype. Family studies suggest autosomal codominant inheritance of the OT145 phenotype. The distribution of the three OT145-defined phenotypes varies considerably in populations of different ethnic background. Taken together these data suggest that the polymorphism detected by OT145 may represent a variable or joining region allotypic system of the human T-cell antigen receptor. In addition, our results indicate that allelic exclusion governs the expression of the clonotypic receptor by human T cells. |

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.
