“…This observation may support our results, reinforced by the fact that severe COVID-19 usually presents a vWF significant increase in plasma levels, with apparently reduced tissue distribution. Elevated vWF levels have been linked to endothelial injury, disease severity, and increased mortality in COVID-19 patients [ 23 , 29 , 33 , 34 , 35 , 36 ]. PAI-1 plays a crucial role in COVID-19, contributing to the prothrombotic state characteristic of the disease.…”

“…Como já é sabido, o Fator VIII endotelial é uma glicoproteina que age como cola entre as plaquetas e a parede dos vasos 15 , e além de atuar na adesão e agregação plaquetária, participa como transportador do Fator VIII de coagulação de origem hepática e, sendo detectado por estudo imunoistoquímico, identifica área em que há plaquetas e vasos, por isso é considerado bom marcador de angiogênese 17 . O CD-34 também é marcador de angiogênese, uma vez que via anticorpo anti-CD-34, marca imunoistoquimicamente células CD-34 +, envolvidas no processo de replicação do endotélio vascular 8 .…”

“…O Fator VIII é uma glicoproteína adesiva de estrutura multimérica produzida exclusivamente por células endoteliais e megacariócitos 15 . Ele permite que as plaquetas fiquem aderidas à parede do vaso, formando uma ponte entre as fibrilas colágenas da parede vascular e receptores situados nas glicoproteínas plaquetárias, como se fossem amarrações entre uma embarcação e o ancoradouro 6 .…”

“…VWF is a multimeric glycoprotein structure, synthesized by endothelial cells in Weibel-Palade bodies and megakaryocytes, it's found in plasma and in the platelets. [5]. VWF is formed by identical sub-units, which have binding sites for both platelet glycoproteins and collagen [6].…”
