| Abstract | CD83 is a widely recognized surface marker for mature dendritic cells, which are essential for priming naïve CD4+ T cells into effector cells. However, CD83 is also expressed on activated CD4+ T cells, which remains an enigma in Tcell mediated immunity. Therefore, the identification of the biological features and regulation of the expression of CD83 on activated CD4+ T cells is important in understanding the function of CD83 in the adaptive immune response. The present study revealed a timedependent manner of the expression of CD83 on antiCD3/CD28stimulated human CD4+ T cells, which is characterized by the maximum expression at day 2 and a significant decrease at day 3. The reduced expression is not a result of a reduced rate of cell proliferation. The activation of interleukin2 and secretion of interferonγ accumulated progressively from day 1 to 3. Of note, sustained expression of CD83 was observed when CD4+ T cells were induced by transforming growth factor-ß to differentiate into CD4+CD25+ forkhead box P3+ regulatory T (iTreg) cells. Confocal immunofluorescence microscopy analysis demonstrated that CD83 was highly colocalized with CD25 on activated CD4+ T cells. In conclusion, the findings of the present study suggested that the continuous expression of CD83 on activated human CD4+ T cells is correlated with their differentiation into iTreg 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.
