| Abstract | The cytokine receptor interleukin (IL)-4R, expressed by lymphocytes, is well known for its role in immunomodulatory signaling and has also been documented on oligodendrocytes, suggesting involvement in glial cell interactions. In the present study, we investigated the clinical course and pathology of experimental autoimmune encephalomyelitis in mice demonstrating deletion of IL-4R and found a correlation with cytokine expression during acute and chronic disease. Wild-type (WT) littermates served as controls. Although IL-4R(-/-) mice displayed a milder course throughout, they showed comparable pathology to WT in the acute phase. However, during the chronic phase, IL-4R(-/-) mice exhibited extensive remyelination and an apparent increase in oligodendrocytes. Cytokine patterns were examined by immunocytochemistry, fluorescence-activated cell sorting, and enzyme-linked immunosorbent assay and were strongly proinflammatory within the central nervous system during the acute phase in WT mice whereas IL-4R(-/-) animals expressed higher levels of IL-6 and IL-10 that became more pronounced with time. The milder experimental autoimmune encephalomyelitis and enhanced remyelination in IL-4R(-/-) mice appeared to be related to a shift toward a Th-2 pattern involving mainly IL-6 and IL-10. These data suggest that IL-4R exerts a negative regulatory role on oligodendrocytes that when deleted results in enhanced myelin repair. |

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.
