TGF-β超家族在阿尔兹海默病中的研究进展刘芬,李湘湘,邹伟*(南华大学衡阳医学院附属南华医院神经内科,衡阳421001)摘要:阿尔茨海默病是一种常见的神经退行性疾病。神经组织中淀粉样斑块的积累和Tau病理的传播在AD的发生发展中起关键作用。转化生长因子-β(TGF-β)超家族由几组高度保守的多功能信号蛋白组成,广泛参与细胞周期调控、分化和免疫等生理过程。TGF-β超家族具有神经保护功能,并在AD病理改变的多个方面起关键作用,包括Aβ沉积、Tau磷酸化、海马神经发生和突触可塑性障碍等。多种TGF-β超家族成员在AD模型中被证明可明显延缓其病程,改善认知功能障碍。本文对TGF-β超家族在AD病理学方面的相关研究进行了系统综述,表明TGF-β超家族的研究在AD治疗中具有巨大潜能。关键词:转化生长因子-β超家族;阿尔兹海默病;认知功能障碍ResearchprogressofTGF-βsuperfamilyinAlzheimer’sdiseaseLIUFen,LIXiangxiang,ZOUWei*(DepartmentofNeurology,AffiliatedNanhuaHospital,HengyangMedicalCollege,UniversityofSouthChina,Hengyang421001,China)Abstract:Alzheimer’sdisease(AD)isacommonneurodegenerativediseaseandismainlyattributedtotheaccumulationofamyloidplaquesandthespreadofTaupathology.Transforminggrowthfactorbeta(TGF-β)superfamilyconsistsofseveralgroupsofhighlyconservedmultifunctionalsignalingproteinsorchestratingmanyphysiologicalprocessesincludingcell-cyclecontrol,differentiationandimmunefunctions.TGF-βsuperfamilyhasneuroprotectivefunctionsandplaysakeyroleinmultipleaspectsofADpathologicalchanges,includingAβdeposition,Tauphosphorylation,hippocampalneurogenesis,andsynapticplasticitydisorders.MultipleTGF-βsuperfamilymembershavebeenshowntosignificantlydelaythecourseofdiseaseandimprovecognitivedysfunctioninADmodels.ThisstudysystematicallyreviewedtherecentprogressofTGF-βsuperfamilyinthepathologyofADtorevealitstremendouspotentialontheresearchofAD.KeyWords:transforminggrowthfactorbetasuperfamily;Alzheimer’sdisease;cognitiveimpairment近年来,阿尔兹海默病(Alzheimer’sdisease,AD)的发病率逐年升高,给家庭和社会经济带来严重负担,被列为全球公共卫生优先事项[1]。AD主要表现为进行性的认知功能障碍,其主要病理生理特征为β-淀粉样蛋白(amyloidβ,...
