However, the activation of multiple complement pathways, dysregulated neutrophil responses, endothelial injury, and hypercoagulability appear to be interlinked with SARS-CoV-2 infection and instead serve to drive the severity of the disease [91] . Regarding SLE, the prototypic systemic autoimmune disease, a group of investigators suggested that inherent epigenetic dysregulation causing hypomethylation and overexpression of ACE2, the functional receptor for SARS-CoV-2, might facilitate viral J o u r n a l P r e -p r o o f entry, viremia, and increased likelihood of cytokine storm in such patients [153] . ./cache/cord-312486-rumqopg0.txt ./txt/cord-312486-rumqopg0.txt
