| Abstract | Potential reasons for the lack of pathogenicity of the simian immunodeficiency virus SIVagm in its natural host, the African green monkey (AGM, Cercopithecus aethiops), were investigated with respect to immunological mechanisms. The functional immune response of monkeys to infection was similar (though not identical) to that of humans to infection with human immunodeficiency virus type 1 (HIV-1). In the sera of infected animals, neutralizing antibodies were found to be low or absent, and in particular there was no neutralization of the various isolates by homologous sera. There was no detectable antibody/complement cytotoxicity, though AGM sera were able to initiate antibody-dependent cellular cytolysis of infected cells in the presence of healthy effector peripheral blood lymphocytes. As in the human/HIV system, macrophages from AGMs are readily infected by SIVagm. Two possibly important differences between the AGM/SIVagm system and the human/HIV system are (i) the low immune response of the AGMs to the core protein of SIVagm and (ii) the significantly lower inhibitory effect of SIVagm proteins on the proliferation of AGM lymphocytes. |

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.
