It is known that age-related alterations of retinal pigment epithelium (RPE) cells and of glial reactivity are early hallmarks of AMD. Here we evaluated contributions of the age-related alterations of the RPE and of glia to the development of AMD-like retinopathy in OXYS rats. We showed that destructive alterations in RPE cells are a primary change during the development of retinopathy in OXYS rats. Furthermore, a defect of retinal maturation and decreased immune function at the preclinical stage of retinopathy were observed in OXYS rats in addition to the impairment of RPE cell proliferation and of their capacity for division. At the active stage of the disease, the atrophic alterations increased, and reactive gliosis was observed when disease progressed, but immune function stayed weakened. Unexpectedly, we did not observe migration of microglia and macrophages into the photoreceptor layer. These results and the wide spectrum of age-related retinal alterations in humans as well as individual differences in the risk of AMD may be attributed to genetic factors and to differences in the underlying molecular events.<\/jats:p>","DOI":"10.1038\/srep41533","type":"journal-article","created":{"date-parts":[[2017,1,30]],"date-time":"2017-01-30T05:18:01Z","timestamp":1485753481000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":48,"title":["Contributions of age-related alterations of the retinal pigment epithelium and of glia to the AMD-like pathology in OXYS rats"],"prefix":"10.1038","volume":"7","author":[{"given":"Darya V.","family":"Telegina","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oyuna S.","family":"Kozhevnikova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergey I.","family":"Bayborodin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nataliya G.","family":"Kolosova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2017,1,30]]},"reference":[{"key":"BFsrep41533_CR1","doi-asserted-by":"publisher","first-page":"299","DOI":"10.1111\/j.1755-3768.2011.02179.x","volume":"90","author":"K Kinnunen","year":"2012","unstructured":"Kinnunen, K., Petrovski, G., Moe, M.
