The review describes correlations between impaired functioning of chaperones and co-chaperones in Alzheimer's disease (AD) pathogenesis. The study aims to highlight significant lines of research in this field. Chaperones like Hsp90 or Hsp70 are critical agents in regulating cell homeostasis. Due to some conditions, like aging, their activity is damaged, resulting in β-amyloid and tau aggregation. This leads to the development of neurocognitive impairment. Dysregulation of co-chaperones is one of the causes of this condition. Disorders in the functioning of molecules like PP5, Cdc37, CacyBP/SIPTRAP1, CHIP protein, FKBP52, or STIP1 play a key role in AD pathogenesis. PP5, Cdc37, CacyBP/SIPTRAP1, and FKBP52 are Hsp90 co-chaperones. CHIP protein is a co-chaperone that switches Hsp70/Hsp90 complexes, and STIP1 binds to Hsp70. Recognition of precise processes allows for the invention of effective treatment methods. Potential drugs may either reduce tau levels or inhibit tau accumulation and aggregation. Some substances neuroprotect from Aβ toxicity. Further studies on chaperones and co-chaperones are required to understand the fundamental tenets of this topic more entirely and improve the prevention and treatment of AD.
该综述描述了伴侣蛋白和共伴侣蛋白在阿尔茨海默病(AD)发病机制中功能障碍的相关性。本研究旨在强调该领域的重要研究方向。伴侣蛋白(如 Hsp90 或 Hsp70)是调节细胞内稳态的关键因子。由于某些情况(如衰老),它们的活性受损,导致β-淀粉样蛋白和 tau 聚集。这导致神经认知障碍的发展。共伴侣蛋白的失调是这种情况的原因之一。像 PP5、Cdc37、CacyBP/SIPTRAP1、CHIP 蛋白、FKBP52 或 STIP1 等分子的功能障碍在 AD 的发病机制中起着关键作用。PP5、Cdc37、CacyBP/SIPTRAP1 和 FKBP52 是 Hsp90 的共伴侣蛋白。CHIP 蛋白是一种切换 Hsp70/Hsp90 复合物的共伴侣蛋白,而 STIP1 与 Hsp70 结合。对精确过程的识别可以开发有效的治疗方法。潜在的药物可能降低 tau 水平或抑制 tau 积累和聚集。一些物质具有神经保护作用,可以抵抗 Aβ 毒性。需要进一步研究伴侣蛋白和共伴侣蛋白,以更全面地了解这一主题的基本原则,并改善 AD 的预防和治疗。
