| Abstract | The role of complement receptors in phagocytosis of herpes simplex virus (HSV) by PMN was examined. Complement components were deposited on the surface of the virus particle in the presence or absence of specific anti-HSV antibodies. Flow cytometry was used to analyze the phagocytosis of fluorescence-labeled viruses and demonstrated that although a virion is able to associate with PMN in the presence of complement alone, the granulocyte is not triggered to mount a metabolic burst. Efficient stimulation of PMN occurs when complexes are formed consisting of virus, specific antibodies, and complement. To address the question whether the viruses were inside or outside the cell, a combined enhancement/quenching method was developed using ammonium chloride as a lysosomotropic agent and trypan blue as a quenching dye. The data indicate that Fc receptor-mediated phagocytosis by PMN results in the ingestion of all cell-associated herpes virions. Interactions of virions through PMN-complement receptors CR1 and CR3 results solely in binding to the PMN but not in internalization. Interactions via both complement and Fc receptors cause synergistic stimulation of the PMN and result in very efficient association of viruses, greater than 80% of which were inside the cell. |

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.
