| Abstract | Human sera contain cytotoxic naturally occurring (CyNa) antibodies which discriminate between lymph node cells from mice differing only at the H-2 complex. Sera from three healthy subjects (normal human sera, NH sera) and one serum from a patient with multiple sclerosis reacted with cells expressing Db, Kd, Kk, and Kp molecules, respectively. However, the following observations suggested that the binding specificity of these CyNa antibodies is to antigens that are distinct from the classical H-2 antigens: (i) the NH sera did not contain cytotoxic anti-HLA antibodies, (ii) redistribution (capping) of H-2 antigens did not induce resistance to lysis for CyNa antibodies, and (iii) individual variation was demonstrated in the expression of the murine lymphocyte antigens detected by the human CyNa antibodies. The reason for this variation appeared to be different for individual NH serum. A maternal effect influenced the expression of the murine lymphocyte antigen detected by one NH serum (anti-H-2b). The differences detected by another NH serum (anti-H-2p) appeared to be inherited, as shown by progeny testing. We hypothesize that the human CyNa antibodies may be directed against antigens controlled or modified by murine viruses (milk borne or endogenous), whose expression is under the influence of the H-2 complex, and that their production might have been stimulated by the products of human genes homologous to murine viruses. |

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.
