| Abstract | Retinitis pigmentosa is a group of inherited eye disorders that result in profound vision loss with characteristic retinal neuronal degeneration and vasculature attenuation. In a mouse model of retinitis pigmentosa, endothelial progenitor cells (EPC) from bone marrow rescued the vasculature and photoreceptors. However, the mechanisms and cell types underlying these protective effects were uncertain. We divided EPC, which contribute to angiogenesis, into two subpopulations based on their aldehyde dehydrogenase (ALDH) activity and observed that EPC with low ALDH activity (Alde-Low) had greater neuroprotection and vasoprotection capabilities after injection into the eyes of an rd1 mouse model of retinitis pigmentosa compared with EPC with high ALDH activity (Alde-High). Of note, Alde-Low EPC selectively recruited F4/80(+) /Ly6c(+) monocyte-derived macrophages from bone marrow into retina through CCL2 secretion. In addition, the mRNA levels of CCR2, the neurotrophic factors TGF-ß1 and IGF-1, and the anti-inflammatory mediator interleukin-10 were higher in migrated F4/80(+) /Ly6c(+) monocyte-derived macrophages as compared with F4/80(+) /Ly6c(-) resident retinal microglial cells. These results suggest a novel therapeutic approach using EPC to recruit neuroprotective macrophages that delay the progression of neural degenerative disease. |

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.
