The long term objective is to elucidate the biochemical properties of cholinesterases in the plaques and tangles of Alzheimer's disease. Anatomical, pathological, histochemical, biochemical, immunohistochemical and ultrastructural methods will be used to identify the unique properties of plaque and tangle-bound cholinesterases. This is and important objective because recent observations have revealed a selective and universal enhancement of cholinesterase activity in all plaques and tangles. Furthermore, it appears that these cholinesterases are different from the cholinesterases may thus play an important role in the pathogenesis of Alzheimer's disease. As part of this research, cholinesterase inhibitors that are optimally suited to inhibit the type of cholinesterases associated with plaques and tangles will be sought and identified. Cholinesterase inhibitors with this type of activity profile may be more effective than currently available substances for the treatment of Alzheimer's disease.

长期目标是阐明 阿尔茨海默氏病的斑块和缠结中的胆碱酯酶。 解剖学，病理，组织化学，生化， 免疫组织化学和超微结构方法将用于识别 斑块和结合缠结的胆碱酯酶的独特特性。 这 是和重要的目标，因为最近的观察结果表明 所有人的胆碱酯酶活性的选择性和普遍增强 斑块和缠结。 此外，看来这些胆碱酯酶 因此，与胆碱酯酶不同可能起重要作用 在阿尔茨海默氏病的发病机理中。 作为这项研究的一部分， 最适合抑制类型的胆碱酯酶抑制剂 将寻求与斑块和缠结相关的胆碱酯酶的 并确定。 具有这种活性的胆碱酯酶抑制剂 个人资料可能比当前可用的物质更有效 治疗阿尔茨海默氏病。
