| Abstract | This study was designed to determine whether natural immune responses could elicit immunoregulatory auto-antiidiotypic antibodies. Female rabbits heterozygous at the a and b Ig loci were bred to homozygous males. Offspring of one such breeding were studied for natural production of antibodies specific for the noninherited allotypes and for the production of immunoregulatory auto-antiidiotypic antibodies. All offspring mounted natural antiallotype responses. The anti-a1 responses cycled as a function of time whereas the anti-b5 responses were invariant. Anti-a1 responses from two offspring were shown to change specificity for different a1 subsets as they cycled. Anti-a1 was purified from the first cycle and was used to assay for auto- antiidiotypic responses. Auto-antiidiotypic antibodies were detected and were found to cycle in an inverse way with the anti-a1 cycles. The idiotopes detected using the natural auto-antiidiotypic antisera were strongly cross-reactive. Subsequent deliberate immunization showed that antibodies specific for all a1 subsets could be elicited after auto- antiidiotypic regulation had functioned. The data support the interpretation that idiotype network interactions indeed function in naturally occurring immunologic situations and are not merely laboratory curiosities or artifacts. |

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.
