| Abstract | One of the most striking examples of localized vascular differentiation is exhibited by specialized lymphoid organ venules that mediate the extravasation of circulating lymphocytes from the blood. These vessels are characterized by cuboidal or "high" endothelial cell morphology and are unique in their functional capacity to interact with migrating lymphocytes, regulating both the rate and specificity of lymphocyte traffic through particular regions of the body. We describe here a monoclonal antibody, MECA-325, that defines an endothelial cell differentiation antigen selectively expressed on high endothelium in the mouse. Thus an antigen defining a specific functional subset of endothelial cells has been found. Furthermore, we demonstrate that the MECA-325 antigen can be induced in mouse lung or bone marrow-derived endothelial cell lines in vitro by interferon-gamma but not by interferon-beta, interleukin-1, or endothelial cell mitogens. The results define a unique marker associated with differentiated endothelial cells mediating lymphocyte traffic from the blood, and they provide evidence that the specialized phenotype of these high endothelial cells may be induced and controlled by local factors associated with immune activity. |

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.
