| Abstract | A characteristic feature of systemic autoimmune diseases, along with the appearance of autoantibodies that target self-antigenes, is the deposition of immunoglobulins and components of the complementary system in kidneys. However, the process of the development of a deposit and its cytotoxic effects still remain poorly studied. To elucidate these questions, we used SJL/J mice, which develop an autoimmune process accompanied by the appearance of anti-fibrillarin antibodies following regular administrations of sublethal dozes of HgCl$_{2}$. Using antibodies to total mouse immunoglobulins, we showed that immunodeposits are present in glomeruli of autoimmune and control (not-autoimmune) animals. The intensity of these antibodies was directly correlated with the titer of anti-fibrillarin autoantibodies and was minimal in control mice. Confocal microscopy and conventional fluorescence microscopy show that immunodeposits deeply penetrate glomeruli and are clearly identified within mesangial cells. Immunoglobulins fully colocolized with the C3-component of the complement, but not with fibrillarin, which is a major autoantigen. We failed to determine the signs of cell proliferation or death in glomeruli. The most prominent difference between control and autoimmune mice was the presence of immunodeposits in renal blood vessels. These observations argue in favor of the idea that destructive and dysfunctional renal lesions that accompany the development of autoimmune diseases can be caused in part by the accumulation of immunodeposits in blood vessels. |

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.
