Common inflammatory markers seen in endothelial dysfunction (Kaur et al., 2018) including C-reactive protein (CRP), IL-6, interferon gamma-induced protein-10 (IP-10), monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1 alpha (M1P1A), and TNF-α were also elevated in patients with COVID-19 (Zhou et al., 2020). This evidence concerns the gene TNF and endothelial dysfunction.
