| Abstract | There are two types, A and B, of Epstein-Barr virus (EBV) and B95-8 represents the common type A laboratory strain. Herein, we show in a family study that paternal EBV-specific cytotoxic T lymphocytes (CTL) generated in short-term cultures following stimulation with the autologous B95-8-transformed lymphoblastoid cell line (LCL) or B cells freshly infected with the B95-8 isolate did not lyse haploidentical B95-8 LCL expressing the HLA-A1, -B8, -DR3 paternal haplotype. In contrast, the haploidentical B95-8 LCL expressing the HLA-A11, -B51, -DR7 paternal haplotype was strongly lysed. Moreover, paternal CTL generated in response to stimulation with the B95-8 LCL expressing the haploidentical HLA-A1, -B8, -DR3 paternal haplotype included an allogeneic response against the maternal haplotype but no EBV-specific response as shown by the poor lysis of the autologous LCL target cells. However, stimulation with the haploidentical HLA-A11, -B51, -DR7 paternal haplotype resulted in the generation of both an allogeneic and an EBV-specific response. CTL clones were generated from two HLA-B8+ donors in response to stimulation with the autologous type A LCL transformed with wildtype EBV. The clones were cross-reactive for an immunodominant B95-8-associated peptide epitope that interacted with the HLA-B8 allele but failed to lyse B95-8-transformed LCL targets unless the targets were pre-coated with the exogenous peptide. A CTL clone that was initially stimulated with the autologous BL74 LCL lysed the spontaneous autologous LCL and spontaneous LCL from an HLA-B8+ donor, but failed to lyse the B95-8 LCL from that donor. The observed haplotype preference can be explained in terms of sequence variation between the B95-8 and the corresponding wildtype epitope. Our findings may help to clarify the role of EBV in the pathogenesis of primary Sjögren's syndrome which is closely associated with HLA-B8. |

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.
