TLR3 and COVID-19: Gene product types may reflect the importance of structural proteins in EDS and immune signaling after COVID-19 infection, with 76 or 25% of EDS-relevant genes being structural (St), versus 6 or 7.2% for COVID-relevant genes, and 39 or 12% of the former having signal (Si) functions versus 20 or 35% of the latter in Figure 2B. Other product proportions are similar, with 3 (11%) of 82 COVID-19-related genes having mitochondrial connections, including STAT2 (elongated mitochondria in muscle), TLR3 (mitochondrial antiviral pathway), and NDUFAF7 (assembly of mitochondrial complex I).
