| Abstract | In this study, we reveal that a neutral polysaccharide isolated from a Chinese medicinal herb, named Ginseng (Panaxgiseng C.A. Meyer), promotes maturation of BMDCs via inducing changes both inside and outside BMDCs, as well as changes of functions. These affects of NGP on BMDCs were evaluated with use of conventional scanning electronic microscopy (SEM), transmission electronic microscopy (TEM) for morphology of BMDCs, flow cytometry (FCM) for key surface markers of BMDCs, cytochemistry assay, FITC-dextran, bio-assay for their phagocytosis and enzyme linked immunosorbent assay (ELISA) for cytokine production by BMDCs. Our results proved that NGP induced maturation of BMDCs as reflected by the downregulation of acid phosphatase (ACP) activity inside the BMDCs, which occurs when phagocytosis of BMDCs decreased, while antigen presentation increased upon maturation. These data also revealed higher expression of MHC II, CD80, CD86, CD83, CD40 and secretion of higher level of IL-12 and low level of TNF- . Our approach suggests that NGP could therefore stimulate the maturation of murine BMDCs through a series of regulation to the BMDCs. |

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.
