Severe COVID-19 is characterized by acute respiratory distress syndrome (ARDS)-like hyperinflammation and endothelial dysfunction, that can lead to respiratory and multi organ failure and death. Interstitial lung diseases (ILD) and pulmonary fibrosis confer an increased risk for severe disease, while a subset of COVID-19-related ARDS surviving patients will develop a fibroproliferative response that can persist post hospitalization. Autotaxin (ATX) is a secreted lysophospholipase D, largely responsible for the extracellular production of lysophosphatidic acid (LPA), a pleiotropic signaling lysophospholipid with multiple effects in pulmonary and immune cells. In this review, we discuss the similarities of COVID-19, ARDS and ILDs, and suggest ATX as a possible pathologic link and a potential common therapeutic target.
严重的 COVID-19 以类似于急性呼吸窘迫综合征(ARDS)的过度炎症和内皮功能障碍为特征,可导致呼吸和多器官衰竭和死亡。间质性肺疾病(ILD)和肺纤维化使疾病严重的风险增加,而 COVID-19 相关 ARDS 存活患者的亚组将发展出一种纤维增生性反应,这种反应在住院后仍会持续存在。自分泌酶(ATX)是一种分泌型溶脂酶 D,主要负责细胞外产生溶血磷脂酸(LPA),LPA 是一种具有多种作用的多效信号溶脂磷脂,对肺和免疫细胞有多种影响。在这篇综述中,我们讨论了 COVID-19、ARDS 和 ILD 的相似性,并提出 ATX 可能是一种病理联系和潜在的共同治疗靶点。
