Development of effective treatments has been hampered by the lack of good experimental models. In a new study published in <em>The American Journal of Pathology<\/em>, researchers describe the distinct stages of prion disease in the mouse retina and define an experimental model to specifically test therapeutic approaches.<\/p>\n<p>The study used an experimental mouse model of the prion disease scrapie to determine the temporal relationship between the transport of misfolded prion protein (PrPSc) from the brain to the retina, the accumulation of PrPSc in the retina, the inflammatory response of the surrounding retinal tissue, and the loss of neurons.<\/p>\n<p>It is believed that transmissible spongiform encephalopathy (TSE) progression depends on the spread of misfolded protein from one central nervous system structure to another. The investigators injected mouse-adapted scrapie into the brains of mice and studied the movement of misfolded prion protein from the brain into the retina via the optic nerve for up to 153 days post-inoculation (dpi), when clinical disease becomes apparent.<\/p>\n<p>By studying prion disease in the retina, which is relatively isolated from the brain, researchers were able to determine the time lag between stages of the disease process and were able to sequentially detect seeding of misfolded protein in the retina at 60 dpi, followed by accumulation of PrPSc and activation of retinal glia at 90 days, activation of microglia at 105 dpi, and retinal neuronal death at 120 dpi.<\/p>\n<p>Using this information, it is now possible to evaluate a potential therapy for its ability to interfere with accumulation of protein misfolding, to suppress damaging neuroinflammation, or to prevent death of neurons.<\/p>\n<p>Paper: <a href=\"http:\/\/ajp.amjpathol.org\/article\/S0002-9440(16)30213-9\/abstract\">&#8220;Temporal Resolution of Misfolded Prion Protein Transport, Accumulation, Glial Activation, and Neuronal Death in the Retinas of Mice Inoculated with Scrapie&#8221;<\/a><br \/>\n<strong>Reprinted from materials provided by <a href=\"https:\/\/www.elsevier.com\/about\/press-releases\/research-and-journals\/cascade-of-events-leading-to-prion-disease-described\">Elsevier<\/a>.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Prion diseases are deadly neurodegenerative disorders in humans and animals [&hellip;]<\/p>\n<a href=\"https:\/\/neurodegenerationresearch.eu\/fi\/2016\/09\/cascade-of-events-leading-to-prion-disease-described\/\">View Post<\/a>","protected":false},"author":3,"featured_media":4980,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[22],"tags":[275,497,496],"class_list":["post-6253","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-research-news","tag-prion-disease","tag-prion-protein","tag-prp"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
