說明

老化是神經退化性疾病(Neurodegenerative diseases)的重要危險因子,神經退化性疾病佔老年人口的比例已經逐年增加,相對的醫療資源用在預防與治療與老年相關的神經疾病,也以同步的速度遞增;其中老年失智症(又稱為阿茲海默症;Alzheimers diseaseAD」)和帕金森氏症(Parkinson’s diseasePD」)無論是歐美或是我國,均是最常見的神經退化性疾病;隨著老年人口的快速增加,可以預期ADPD或其他神經退化性疾病將是未來影響全球醫療、經濟、家庭與社會的重要議題。欲思對神經退化性疾病的防制有所突破,必須從多方面的醫療與研究著手,才能收到預期的成效。有鑑於世界各國的醫療團隊不乏有卓越的阿茲海默氏症和帕金森氏症研究中心,本研究團隊建立的主要目的乃利用長庚大學醫、工與管理學院對神經老化疾病既有的研發基礎與長庚醫療體系龐大的資料庫做人力與資源的配合與整合,期能開發早期預警的生物指標(biomarker)、生物標記(biosignature)與開創神經退化性疾病特有的動物與細胞模式,提供基礎研究從事病變機轉或連結臨床疾病判斷和當做藥物測試平台;此外將藉由醫工與管理專才對健康老年人和神經退化病患的生理參數作數據整合與分析,提供臨床醫護未來對老年生活品質提升的重要依據。本研究團隊成立的初期是以神經退化性疾病的各研究平台建立為主要目標,目前業已開發出各種研究退化性疾病的細胞與動物模式,並積極與國際一流醫學研究團隊建立團隊合作關係,使本中心的神經科學群達到國際頂尖的水準,以培訓本中心基礎研究人才,達到卓越與國際化的目標。未來本中心的發展將參考國外研究退化性疾病的最新趨勢,擴充本研究團隊的動能與開發新的研究議題,以符合科研精進的精神與目的。

 

背景

神經退化性疾病是一個緩慢的病變過程,涉及遺傳與非遺傳的環境因素,經由共通性的病理變化造就最終的疾病表徵(disease phenotypes),瞭解疾病的起始原因和過程除可掌握病情的發展外,尚可發展出早期預警指標,以幫助病患改善生活品質,並節省社會醫療成本。在眾多的神經退化性疾病中,阿茲海默症和帕金森氏症的罹病人口最多,帶給家庭與社會上的壓力也最大,而背後的原因複雜,包括體內氧化壓力的上升、代謝症候群、免疫力下降導致的慢性感染和發炎因子在腦部的堆積等等因素。其中帕金森氏症患者腦部或因基因的突變或因外在環境因子的誘發,導致a-synuclein蛋白的堆積,形成Lewy body的病理結構,致使紋狀體內多巴胺神經末稍退化影響運動功能;而阿茲海默症患者在大腦皮質和海馬迴因為b-amyloid蛋白的不正常聚合而形成plague的病理結構,或是因為Tau蛋白質過度磷酸化而導致微管(microtubule)的崩散,這些病理變化最終造成患者的失智症與認知功能受損。有鑑於此,國內最龐大的醫療體系-長庚醫院業已成立相關的研究中心,針對失智症、帕金森氏症和運動功能障礙從事病理分析、臨床診斷與基礎研究。本校老化中心內的「神經退化性疾病研究團隊」在過去頂尖大學研究計畫的經費支助下成立,當時即與長庚醫院既有的醫療研究團隊以及「神經科學中心」充分合作,利用長庚醫療體系的病患基因檢體分析與分子影像檢析,與本校各個核心實驗室(蛋白質體中心、生醫影像中心、基因體中心、代謝體中心、生物資訊實驗室)的尖端研發平台,並配合「動物行為核心實驗室」的設立,得以縱深性的從生物指標的確認到動物模式的建立與臨床病例做關聯,達到相輔相成的成效,與基礎與臨床結合的目標。此外,本中心以早期預警的生物標記為主要研究目標,所獲得的資料將可與老化中心內其他研究團隊配合與合作,以建構起多方位的老年醫療研究中心,提升國民健康指數。

 

目的

神經退化性疾病是一個緩慢的病變過程,涉及遺傳與非遺傳的誘發因子,經由共通性的病理變化造就最終的疾病表徵(disease phenotypes),瞭解疾病的起始原因除可掌握病情的發展外,並可發展出早期預警指標,幫助病患改善生活品質減緩疾病的發展過程,以節省整體社會醫療成本。在眾多的神經退化性疾病中,阿茲海默症和帕金森氏症的罹病人口最多,帶給家庭與社會上的壓力也最大;有鑑於此,本研究團隊成立的主要目的在於開發神經退化性疾病的各細胞與動物模式,以提供退化性疾病病變過程的機制研究、測試環境因子導致神經退化的原因與治療性藥物測試的平台,我們的利基在於長庚醫療體系已有神經科學中心、失智症中心與帕金森氏症研究中心,針對退化性疾病與運動功能障礙從事病理分析與臨床診斷,尤其利用遺傳分析與分子影像造影技術已成功的確認若干家族性病例的基因病變位點。本中心的成立除可利用本校既有的各核心實驗室的研發平台,配合臨床病例以開發出特有的退化性疾病動物與細胞模式,達到基礎與臨床結合的目標,以期最終能增進全民健康福祉。

 

方法

一)開發退化性疾病的生物指標或標記(biomarker/biosignature identification:利用帕金森氏症和失智症病患的基因、血液或其他生物檢體,配合長庚大學既有的分析平台:例如基因體學、次世代基因定序(NGS)、蛋白質體學、代謝質體學、分子及生醫影像和生物資訊等尖端的分析平台,綜合性與複合式的搜尋病變基因位點、早期預警生物指標或病變的生物標記以及腦病變過程的分子影像profile,提供臨床病變過程的追蹤與確認。此外,我們也藉由團隊中具光電專長的周晟教授利用高靈敏的SPR表面電漿技術偵測帕金森氏症血液中a-synuclein以及失智症患者血液中b-amyloid不正常蛋白質聚合體的形成,當作早期預警或疾病進展的生物指標。

(二)神經退化性疾病的細胞與動物模式研究(disease models):神經退化性疾病的成因包含諸多環境因子與基因的交互作用,藉由生物指標的開發、我國特有病變家族的基因型確定以及環境毒素(environmental toxin)的確認等先決條件,可供長庚實驗動物中心製作特定的失智症或帕金森氏症動物模式;並利用業已於HARC設立的動物行為及活性實驗室的測試平台做功能性評估;此外,藉由本團隊吳瓊媛老師先進的piggyBac iPS (induced pluripotent stem cell)技術,可以開發出疾病特有的細胞模式,供研究者了解病變的細胞生理過程和做藥物篩選平台;或是利用神經腫瘤細胞株予以發炎因子的刺激當作模擬神經細胞病變退化的細胞模式。這些動物和細胞模式的成功建立,對未來相關神經退化性疾病的諸多研究課題,進行系統性的機制探討。

(三)老年醫療的整合性生物資訊:神經退化性疾病發作前的各項生理參數往往可提供極有價值的醫療資訊,配合生物指標的偵測,作為疾病發作前的臨床預警。利用長庚醫、工、管經營「養生文化村」既有的研發經驗導入失智症與退化性疾病的研究群,將可提供老化研究重要的資訊平台。充分運用Dr. E觀念做非侵入性檢測、無線追蹤日常生活作息、人際活動、飲食與生理參數,提供未來老化研究與退化性疾病發展的重要參考數據。

(四)推動國際合作機制:本研發團隊建立的另一目標就是藉由提升研發深度以達國際頂尖研究的水準,已利推動國際合作。團隊內的神經內科陸清松醫師長期與荷蘭鹿特丹(Rotterdam, NetherlandsErasmus醫學中心有研究合作,將分析有關帕金森氏症家族性病變的特定致病基因,此外生醫影像團隊也參與多項的國際廠商合作,在這樣的基礎上我們未來將持續推動進行以深化合作基礎,對本團隊的研究國際化將具有正面的意義。
