High titers and low fucosylation of early human anti–SARS-CoV-2 IgG promote inflammation by alveolar macrophages
Excessive inflammation is a characteristic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, particularly in patients that are hospitalized with coronavirus disease 2019 (COVID-19). Here, Hoepel et al. investigated how human antibodies specific to SARS-CoV-2 spike protein may contribute to exacerbated inflammation. The authors found that spike protein–specific antibodies from patients with COVID-19 who were hospitalized had altered glycosylation, with an enrichment in ...
