claim: afucosylated immunoglobulin g responses are a hallmark of dengue virus infections and show an exacerbated phenotype in covid-19
evidence_1: here, we report that afucosylated igg which are of minor abundance in humans (6% of total igg) are specifically formed against surface epitopes of enveloped viruses after natural infections or immunization with attenuated viruses, while protein subunit immunization does not elicit this low fucose response.", "in the case of covid-19, the critically ill show aggravated afucosylated-igg responses against the viral spike protein.", "our findings indicate antibody glycosylation as a potential factor in inflammation and protection in enveloped virus infections including covid-19."
