| Abstract | Regulatory T (Treg) cells are being used to treat autoimmunity and prevent organ rejection; however, Treg cell-based therapies have been hampered by the technical limitation in obtaining a high number of functional Treg cells. In this study, we show how to generate functional Treg cells from induced pluripotent stem (iPS) cells and to determine the potential role of such cells for Treg cell-based immunotherapy against autoimmunity in a therapeutic setting. Ligation of a Notch ligand and transduction of the gene Foxp3 induce iPS cells to differentiate into Treg cells. Expression of Foxp3 and coculture on Notch ligand-expressing stromal cells augment expression of CD3, TCR, CD4, CD25, and CTLA-4 on iPS cell-differentiated Treg cells, which are able to secrete TGF-ß and IL-10 both in vivo and in vitro. Importantly, adoptive transfer of iPS cell-derived Treg cells expressing large amounts of Foxp3 and Bcl-x(L) significantly suppresses host immune responses and reduces arthritis development within murine models. These data suggest that Notch signaling and Foxp3 regulate the development and function of Treg cells derived from iPS cells. Our results provide a novel approach for generating potentially therapeutic Treg cells for the treatment of autoimmune diseases. |

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.
