慢性魚(yú)藤酮小鼠模型中鐵與alpha-突觸核蛋白分布的相關(guān)性研究
發(fā)布時(shí)間:2021-07-03 12:37
帕金森病(Parkinson’s disease,PD)是一種常見(jiàn)的神經(jīng)退行性疾病,其主要病理特征包括中腦黑質(zhì)(substantia nigra,SN)多巴胺能神經(jīng)元的選擇性缺失,殘存的神經(jīng)元內(nèi)出現(xiàn)以alpha-突觸核蛋白(alpha-synuclein,α-syn)為主要成分的嗜酸性包涵體即路易小體(Lewy bodies,LBs)。Braak分級(jí)學(xué)說(shuō)認(rèn)為L(zhǎng)Bs的病理改變是一個(gè)從低位腦到高位腦的漸變過(guò)程。其典型的臨床表現(xiàn)包括:靜止性震顫、肌強(qiáng)直、運(yùn)動(dòng)遲緩、姿勢(shì)反射障礙等。而在運(yùn)動(dòng)癥狀出現(xiàn)之前,PD病人常出現(xiàn)嗅覺(jué)功能障礙、便秘、焦慮、體位性低血壓等非運(yùn)動(dòng)癥狀;赑D病人和PD動(dòng)物模型的大量研究發(fā)現(xiàn),PD病理情況下SN區(qū)鐵水平明顯增高,α-syn異常聚集往往伴有鐵的沉積。鐵能夠促進(jìn)α-syn聚集,而α-syn作為鐵代謝相關(guān)蛋白也影響鐵的沉積。LBs中的α-syn 90%以上都以磷酸化形式存在,磷酸化修飾后的α-syn可能更易聚集。為闡明鐵沉積與磷酸化alpha-突觸核蛋白(phosphorylated alpha-synuclein,phos-α-syn)之間的分布關(guān)系。本實(shí)驗(yàn)用12月...

魚(yú)藤酮對(duì)小鼠OB部位鐵含量的影響
9圖 1.2 魚(yú)藤酮對(duì)小鼠 DMV 區(qū)鐵含量的影響Fig. 1.2 Effect of rotenone on iron levels in the DMVls in the DMV of different groups using Perls' iron staining. Bn staining positive cells increased significantly in the DMV of after 3 months. No changes were observed from 1 week to 2 ated mice (***P< 0.001, n=6).
10圖 1.3 魚(yú)藤酮對(duì)小鼠 RP 區(qū)鐵含量的影響Fig. 1.3 Effect of rotenone on iron levels in the RPlls in the RP of different groups using Perls' iron staining. B: Statin staining positive cells increased significantly in the RP of rotenr 3 months. No changes were observed from 1 week to 2 months meated mice (*P< 0.05, n=6).
