载脂蛋白AI(apoAI)是高密度脂蛋白的主要成分,是阿尔茨海默病中观察到的老年斑的主要淀粉样纤维蛋白和次要成分之一。我们在这项研究中研究了apoAI在各种系统性淀粉样变性中的共定位。48例福尔马林固定石蜡包埋的心脏标本中有43例与抗人apoAI抗体发生化学反应。通过免疫印迹法在水提取的淀粉样物质中也检测到ApoAI。此外,我们还观察到apoAI和小鼠淀粉样蛋白A(AA)淀粉样变性在人apoAI转基因小鼠中的共定位。这是第一次报告共定位apoAI与淀粉样蛋白沉积在各种形式的人类系统性淀粉样变性和小鼠AA淀粉样变性在人类apoAI转基因小鼠。ApoAI可能并不总是淀粉样纤维的主要成分,即使它存在于系统性淀粉样沉积物中。
Apolipoprotein AI (apoAI), a major component of high-density lipoproteins, is one of the major amyloid fibril proteins and a minor constituent of the senile plaques observed in Alzheimer's disease. We examined colocalization of apoAI in various kinds of systemic amyloidosis in this study. Forty-three of 48 formalin-fixed paraffin-embedded heart specimens with various forms of systemic amyloidosis reacted immunohistochemically with anti-human apoAI antibody. ApoAI was also detected in water-extracted amyloid material by immunoblotting. In addition, we observed colocalization of apoAI and murine amyloid A (AA) amyloidosis in human apoAI transgenic mice. This is the first report of colocalization of apoAI with amyloid deposits in various forms of human systemic amyloidosis and murine AA amyloidosis in human apoAI transgenic mice. ApoAI may not always be a major component of amyloid fibrils, even when it is present in systemic amyloid deposits.
