| Abstract | Dominant expression of T-cell receptor (TCR) alpha or beta chain variable region (V alpha or V beta) gene families has been observed in the T-cell response to some conventional peptide antigens. Current models for the interaction of TCR V region elements with different determinants of a major histocompatibility complex (MHC)-peptide complex, the normal TCR ligand, suggest that the TCR V-J junctional region (CDR3, where J is joining) is the primary contact with a peptide epitope and that other TCR V region segments may interact directly with neighboring MHC determinants. This suggests that V alpha or V beta dominance in a specific response can be MHC-selected. In this case, if related peptides bind to an MHC molecule in a similar orientation, they could select for identical V alpha or V beta dominance even if they are noncrossreactive at the level of T-cell activation. We have screened for this possibility by introducing minimal conservative substitutions in a synthetic peptide, YYEELLKYYEELLK, that is presented to T cells in association with an uncommon A beta E alpha d mixed Ia isotype. We report here that the peptide variant FFEELLKFFEELLK is noncrossreactive with YYEELLKYYEELLK but appears to preserve the same MHC binding motif since T-cell responses are restricted to the same mixed A beta E alpha isotype. Although the two peptides are noncrossreactive in either direction, the same members of the V alpha 4 gene family are dominantly expressed in T cells specific for either peptide. We conclude that the similar topography of the two MHC-peptide complexes gives functional significance to a unique A beta E alpha determinant that selects for V alpha 4 dominance. |

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.
