| Abstract | Erosive oral lichen planus (OLP) is a chronic, disabling mucocutaneous dysimmune rare disease characterized by mucosal inflammatory erosive lesions with pathological evidence for a marked CD8+ cytotoxic T-lymphocyte (CTL) infiltration. However, the specificity of lesional CTL in OLP has never been analyzed. To investigate the molecular mechanisms underlying dysregulation of T-cell immune responses in patients with OLP, we studied the diversity and antigen specificity of the TCR expressed by CD8+ T cells using dextramer staining, spectratyping, and TCR sequencing in 10 OLP patients undergoing extracorporeal photochemotherapy. Expansions of TCRVß3-bearing CD8+ T cells were found in peripheral blood and in lesional tissues of OLP patients. Spectratyping and sequencing studies identified specific clonotypes in each patient. These expansions were enriched with human papillomavirus 16 (HPV16)-specific CD8+ T cells in HLA-A*0201+ patients as shown by their immune recognition of the E711-20 immunodominant epitope. Under treatment with extracorporeal photochemotherapy, clonotypic CD8+ T-cell expansions decreased in parallel with clinical remission. Altogether, these data establish a link between HPV infection and OLP pathogenesis by identifying a massive clonal expansion of CD8+ T cells with increased frequency of HPV 16-specific CD8+ T cells in OLP patients. |

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.
