| Abstract | PURPOSE: To evaluate whether nerve fibers of the subbasal nerve plexus (SNP) and dendritic cells (DCs) are in association with each other leading to neuropathy in the diabetic cornea. METHODS: BALB/c mice were injected with streptozotocin (STZ) for 5 days for induction of diabetes mellitus (DM) or with vehicle solution (control). B6.VLep(ob/ob) (ob/ob) mice served as an obese and glucose-intolerant DM type 2 (DM II) model and lean B6.VLep(ob/+) (ob/+) mice as respective controls. Using in vivo corneal confocal microscopy (CCM), nerve fibers and DCs were quantified over a period of 9 weeks and additionally analyzed by in vitro immunofluorescence whole-mount staining. RESULTS: In STZ-diabetic mice, CCM revealed an increase of DC density (DCD) in contrast to controls, whereas nerve fiber density (NFD) was decreased with duration of DM. In ob/ob mice, DCD was 3-fold higher than in both ob/+ mice and STZ-diabetic mice. Whole-mount staining displayed CD11c(+) and major histocompatibility complex (MHC) class II(+) mature DCs in colocalization with class III ß-tubulin(+) nerve fibers in the cornea. CONCLUSIONS: Hyperglycemia leads to corneal DC infiltration, and obesity aggravates this immune response. The direct contact between DCs and the SNP can be assumed to be a trigger of nerve fiber damage and thus a contributing factor to polyneuropathy in diabetic corneas. |

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.
