The complexity of coagulopathy pathogenesis in COVID-19
Abstract
Summary. Background. The coronavirus SARS-CoV-2 is a new virus capable of human-human transmission and inducing a severe atypical pneumonia often associated with coagulopathy. A role of SARS-CoV-2 structural proteins in coagulopathy pathogenesis is unknown. Objectives: to use a bioinformation analysis to identify SARS-CoV-2 sequences in the structural proteins that are homologous to hemostasis system proteins, regard their possible participation in coagulopathy pathogenesis and explain the antiviral effect of heparin. Materials/Methods. For computer analysis, Internet databases were used of the primary structures of coronavirus proteins and their receptors, as well as surface proteins of other viruses, proteins of hemostasis and immune systems. The amino acid composition of proteins and the distribution of basic amino acids (arginine and lysine) in their primary sequences were compared. For detection of peptide (immunoepitopic) relationship of coronaviruses structural proteins with human hemostasis proteins, a search for homologous sequences in their proteins was performed. Results. Many sequences have been identified in structural proteins of SARS-CoV-2 coronavirus that are homologous to the proteins of hemostasis and immune systems. In contrast with SARS-CoV and MERS-CoV coronaviruses, the S1-subunit of SARS-CoV-2 coronavirus S-protein has a positive polarity. Conclusions. Many sequences in SARS-CoV-2 structural proteins that homologous to hemostasis system proteins are…
