Amyloid Fibrils03:03

Amyloid Fibrils

9.6K
Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Alzheimer's Disease: Overview

539
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

概括

在像阿尔茨海默氏症 (AD) 这样的病中,FKBP52蛋白在神经元中减少,这表明它在清除中发挥了作用. 恢复FKBP52水平可能为这些神经退行性疾病提供新的治疗策略.

科学领域:

  • 神经科学是一个神经科学.
  • 细胞生物学 细胞生物学
  • 病理学 病理学 病理学

背景情况:

  • 病理性陶蛋白在阿尔茨海默氏症 (AD),渐进性超核性麻 (PSP) 和前叶退化 (FTLD-Tau) 等陶病症中形成神经纤维状.
  • FKBP52 (FK506结合蛋白52) 免疫基因与tau相互作用,并减少AD大脑神经元,与tau沉积相关.
  • 在AD神经元中,FKBP52与自酶体标志物和早期病理性共同局部化,这表明它在自细胞清除中可能发挥作用.

研究的目的:

  • 与对照对神经元FKBP52表达和定位在AD,PSP,家族FTLD-Tau和hTau-P301S小鼠模型中的差异进行调查.
  • 为了确定FKBP52水平和局部是否在病的早期阶段发生变化.

主要方法:

  • 免疫性光分析和FKBP52的定量测定在从陶病患者的死后人脑样本.
  • 来自hTau-P301S小鼠的脊髓样本的分析.

主要成果:

  • 在各种陶氏病变和hTau-P301S小鼠中观察到FKBP52的减少及其与神经元自-溶解体通路内的早期病理性陶氏形式的同定位.
  • FKBP52的减少发生在病理过程的早期,在布拉克IVAD大脑中的tau沉积的神经元和无症状的年轻hTau-P301S小鼠中明显.

结论:

  • 这些发现表明FKBP52在细胞信号传递和清除中发挥作用.
  • 预防FKBP52下降或在早期病理阶段恢复其表达可能是治疗病症的新治疗方法,包括AD,FTLD-Tau和PSP.
