Tg (M83 +/-: GFAP -Luc +/-) periton içine alfa-sinüklein fibrillerinin Çevresel enjeksiyon farenin sinükleinopatilerin önemli özelliklerini özetlemek için nöro eşlik nörolojik hastalık oluşturmak için, basit bir yöntemi temsil eder. Benzer bir şekilde, dil enjeksiyon transgenik farelerde alfa-sinüklein prionoids ile neuroinvasion için başka bir yol tasvir eder fakat daha az etkilidir. Biz enjeksiyon sonrası 420 gün bizim deneyler sonlandırmak için seçti ve biz daha ...

alfa-sinüklein özellikle kendinden tohuma sıfatıyla prion proteininin benzeyen ve hücreler arasındaki ve nöronal yollar boyunca yanlış katlanması yaymak özelliklere sahip olduğunu kanıtlar gittikçe artmaktadır. Alfa-sinüklein Bu özellik aynı zamanda &#39;prion-benzeri&#39; ya da &#39;prionoid&#39; olarak adlandırılır, ve yeni sağlıklı nöronlar 1, 2 nakledilen hastalıklı nöronlardan yanlış katlanmış alfa-sinüklein bulaşıcılığını göstermektedir nakli deneylerinde, gözlem ile desteklenmektedir , 3, 4. Ayrıca beyin veya çevresine, örneğin arka bacak, kas veya bağırsak duvarı, distal kısımlarına alfa-sinüklein patoloji yayılması ile sonuçlanır içine yanlış katlanmış alfa-sinüklein doğrudan enjeksiyon MSS 5, 6, 7, &lt;sup sınıfı = &quot;xref&quot;&gt; 8, 9, 10. Daha ayrıntılı olarak, periferik yollar ile alfa-sinüklein prionoids iletimini analiz edilmiş ve yanlış katlı alfa-sinüklein, tek intraglossal veya intraperitoneal enjeksiyondan sonra daha önce prionlar için değil, yanlış katlanmış alfa- için gösterilmiş olan bir özellik merkezi sinir neuroinvade olup olmadığı sorusunu ele synuclein. Dillerine prionların enjeksiyonundan sonra, CNS neuroinvasion beyin sapı 11 bulunur hipoglosal sinir, çekirdeğine neden dilin hipoglosal sinir boyunca yayılımı ile elde edilir. Tarafından astrositik aktivasyon izleme prion promotöründen insan alfa-sinüklein A53T mutantını aşırı ifade eden, ve ateş böceği bir GFAP promotörünün kontrolü altında lusiferaz fareler: bir fare modelinde olarak, Tg (GFAP -Luc +/- M83 +/-) seçtik biyoışıldama, daha önce beyinde de gösterildiği gibifareler 12 prion ile enfekte. Bizim ellerde bigenic Tg (M83 +/-: GFAP -Luc +/-) başkaları 13 tarafından gösterildiği gibi fareler yaşı 23 aya kadar hastalık olmadı. Beyinlerinde patolojisi ve Tg omurilik ile intraglossal ya da intraperitoneal yol kaynaklı nörolojik hastalık ile insan alfa-sinüklein fibrillerinin bir tek bir enjeksiyonu: hipotezi destekleyen farelerde (+/- M83 +/- GFAP -Luc) alfa-sinüklein prionoids prionların 14 ile önemli özellikleri paylaşır.

bioluminescence imaging of neuroinflammation in transgenic mice after peripheral inoculation of alpha-synuclein fibrils

yanlış katlı alfa-sinüklein prion benzeri bir davranış çalışma yapmak için, fare modelleri, merkezi sinir sistemi (CNS) içinde nevropatlojinin neden olan alfa-sinüklein prionoids, hızlı ve basit bir iletimine izin verir ihtiyaç vardır. Farelerde, prion proteini promoterinden A53T mutasyonu ile insan alfa-sinükleinin aşırı ifade eden ve ateş böceği lusiferaz: Burada bigenic Tg (GFAP -Luc +/- M83 +/-) içine alfa-sinüklein fibrillerinin bu intraglossal veya intraperitoneal enjeksiyon tarif glial fibriller asidik protein promotörü (GFAP), nöropatolojik hastalık oluşturmak için yeterlidir. Hayvanların bir ulaşana kadar spontan hastalığı serbest kalır: 8 ay, heterozigot Tg (GFAP -Luc +/- M83 +/-) bir yaşta başlayan şiddetli nörolojik semptomlar gelişebilir homozigot Tg (M83 + / +) fareler karşılaştırıldığında 22 ay yaşı.
