| Abstract | Objective and Design: We investigated a signal transduction pathway involved in NGF induced histamine secretion from mast cells. We compared this mechanism with the exocytosis induced by basic secretagogue compound 48/80.Materials and Methods: Isolated rat peritoneal mast cells were obtained from male Wistar rats. Histamine release was assayed spectrofl uorometrically.Results: We found that tyrosine kinase inhibitor genistein, phospholipase C (PLC) inhibitor U-73122, phosphatidylinositol 3-kinase (PI-3 kinase) inhibitor wortmannin, protein kinase C (PKC) inhibitors, staurosporine and GF109203X, but not MAP kinase inhibitors, SB203580 and PD98059, reduce histamine secretion in NGF provoked mast cell degranulation. In compound 48/80 mediated degranulation, we confi rmed only the involvement of tyrosine kinase and PLC, but not PI-3 kinase, PKC and MAP kinases.Conclusions: Our results indicate that release of histamine from mast cells after stimulation with NGF is regulated by tyrosine kinase, PLC, PI-3 kinase and PKC, but not by MAP kinases. This biochemical pathway differs from that provoked by compound 48/80. |

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.
