Complement lectin pathway activation is associated with COVID-19 disease severity, independent of MBL2 genotype subgroups
IntroductionWhile complement is a contributor to disease severity in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, all three complement pathways might be activated by the virus.Lectin pathway activation occurs through different pattern recognition molecules, including mannan binding lectin (MBL), a protein shown to intera
