Alzheimer's disease (AD) is an irreversible neurodegenerative disease. Recent identification of AD biomarkers has led to the diagnosis of AD before the onset of dementia. It has been shown that Drosophila melanogaster is a valuable model for studying human neurodegeneration, including AD. According to its properties, curcumin shows promising potential for the diagnosis of AD. In order to improve its use, new formulations, including nanotechnology-based delivery systems, have been applied. The current study aims to diagnose AD by detecting the accumulation of amyloid beta-peptide via carbon-dot-curcumin nanoparticle conjugation in Drosophila. The accumulation of amyloid beta-peptide has been detected via the conjugate using the fluorescence imaging technique. These results suggest that carbon-dot-curcumin nanoparticle conjugation could be used as a diagnostic tool for AD.
阿尔茨海默病(AD)是一种不可逆转的神经退行性疾病。最近 AD 生物标志物的鉴定导致在痴呆症发作前可以对 AD 进行诊断。已经表明,黑腹果蝇是研究人类神经退行性变(包括 AD)的有价值的模型。根据其特性,姜黄素在 AD 的诊断中显示出有希望的潜力。为了提高其用途,包括基于纳米技术的递药系统在内的新制剂已被应用。本研究旨在通过检测果蝇中碳点-姜黄素纳米粒子缀合物对淀粉样β肽的积累来诊断 AD。通过荧光成像技术检测到淀粉样β肽的积累。这些结果表明,碳点-姜黄素纳米粒子缀合物可作为 AD 的诊断工具。
