Further indicators of immune evasion include ST3GAL1 which is carried in circulation by platelets and released upon activation37 and ST3GAL1-mediated O-linked sialylation of CD55 act as CD55-mediated immune evasion38 and the dramatic early proinflammatory IL10 elevation which may play a pathological role in COVID-19 severity proinflammation and T-cell exhaustion4. This evidence concerns the gene CD55 and COVID-19.
