2021年1月9日,西湖大學郭天南等研究人員合作在《細胞》雜誌發表論文,該研究繪製出COVID-19屍檢樣本中不同器官的蛋白質組學圖譜。
研究人員報導了19個COVID-19患者中來自七個器官144個屍檢樣品的蛋白質組學分析。研究人員對這些樣品中的11394種蛋白質進行了定量,其中COVID-19患者與對照組相比有5336種蛋白質被幹擾。這些數據顯示,COVID-19患者的肺組織蛋白酶L1而非ACE2顯著上調。在多個器官中檢測到全身性過度炎症以及葡萄糖和脂肪酸代謝的失調。
研究人員還觀察到COVID-19患者多個器官中涉及缺氧、血管生成、血液凝固和纖維化的關鍵因素失調。睪丸損傷的證據包括Leydig細胞的減少、膽固醇生物合成和精子活動的抑制。
總而言之,這項研究報導了COVID-19屍檢樣品中多種器官的蛋白質組學結果,這將進一步加深人們對COVID-19病理生物學基礎的理解。
據介紹,COVID-19患者多器官損傷的分子病理學仍不清楚,這阻止了有效治療方法的發展。

Abstract: The molecular pathology of multi-organ injuries in COVID-19 patients remains unclear, preventing effective therapeutics development. Here, we report a proteomic analysis of 144 autopsy samples from seven organs in 19 COVID-19 patients. We quantified 11,394 proteins in these samples, in which 5336 were perturbed in the COVID-19 patients compared to controls. Our data showed that cathepsin L1, rather than ACE2, was significantly upregulated in the lung from the COVID-19 patients. Systemic hyperinflammation and dysregulation of glucose and fatty acid metabolism were detected in multiple organs. We also observed dysregulation of key factors involved in hypoxia, angiogenesis, blood coagulation and fibrosis in multiple organs from the COVID-19 patients. Evidence for testicular injuries include reduced Leydig cells, suppressed cholesterol biosynthesis and sperm mobility. In summary, this study depicts a multi-organ proteomic landscape of COVID-19 autopsies that furthers our understanding of the biological basis of COVID-19 pathology.
