严重急性呼吸综合征冠状病毒2(SARS-CoV-2)是许多病理过程的原因,包括改变血管疾病的发展,功能障碍性血栓形成和炎症反应的加剧。然而,有有限的工作,以确定暴露于SARS-CoV-2结构蛋白诱导的潜在细胞反应。因此,我们的目的是研究人动脉外膜成纤维细胞炎症,血栓形成和糖尿病疾病标志物是如何改变响应刺突,核衣壳和膜包膜蛋白。我们假设,在短期暴露于SARS-CoV-2蛋白后,外膜成纤维细胞将具有更高的炎症、血栓形成和糖尿病蛋白表达,这将支持改变血管疾病进展的机制。孵育后,gC 1 qR、ICAM-1、组织因子、GLUT-4和TGF-β 1的表达显著上调。总的来说,每种SARS-CoV-2蛋白的表达程度是不同的,这表明SARS-CoV-2蛋白通过不同的机制与细胞相互作用。因此,SARS-CoV-2蛋白与血管细胞的相互作用可能调节血管疾病的反应。
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for many pathological processes, including altered vascular disease development, dysfunctional thrombosis and a heightened inflammatory response. However, there is limited work to determine the underlying cellular responses induced by exposure to SARS-CoV-2 structural proteins. Thus, our objective was to investigate how human arterial adventitial fibroblasts inflammation, thrombosis and diabetic disease markers are altered in response to Spike, Nucleocapsid and Membrane-Envelope proteins. We hypothesized that after a short-term exposure to SARS-CoV-2 proteins, adventitial fibroblasts would have a higher expression of inflammatory, thrombotic and diabetic proteins, which would support a mechanism for altered vascular disease progression. After incubation, the expression of gC1qR, ICAM-1, tissue factor, RAGE and GLUT-4 was significantly up-regulated. In general, the extent of expression was different for each SARS-CoV-2 protein, suggesting that SARS-CoV-2 proteins interact with cells through different mechanisms. Thus, SARS-CoV-2 protein interaction with vascular cells may regulate vascular disease responses.
