CD55 and viral myocarditis: Additionally, the enrichment of the “Viral myocarditis” pathway (Figure S8), stemming from the strong upregulation of CD55* (aka DAF, encoding a glycoprotein that regulates the complement cascade), would positively regulate the tyrosine kinases ABL1/2 and the small GTP-binding proteins RAC1/2/3, leading to actin reorganization.
