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 low-fucosylated antibodies. These antibodies were able to activate human macrophages in vitro to secrete proinflammatory cytokines. Thus, altered antibody glycosylation may contribute to disease severity in COVID-19.

Patients diagnosed with coronavirus disease 2019 (COVID-19) become critically ill primarily around the time of activation of the adaptive immune response. Here, we provide evidence that antibodies play a role in the worsening of disease at the time of seroconversion. We show ....

Mauna Kea Technologies Supports Clinical Research Evaluating the Use of Cellvizio on COVID-19 Patients with Respiratory Insufficiency


Mauna Kea Technologies Supports Clinical Research Evaluating the Use of Cellvizio on COVID-19 Patients with Respiratory Insufficiency
Regulatory News:
Mauna Kea Technologies (Euronext: MKEA) (Paris:MKEA) (OTCQX:MKEAY) inventor of Cellvizio, the multidisciplinary probe and needle-based confocal laser endomicroscopy (p/nCLE) platform, is supporting research to determine if Cellvizio can be effective in severe acute and/or long COVID-19 patients suffering from lingering respiratory complications. Mauna Kea Technologies is offering in-kind funding to researchers evaluating what role Cellvizio may play in the care management of COVID-19 patients, by assessing lung fibrosis and microvascularization changes, and alveolar and capillary morphology damages; symptoms observed in severe acute and/or long COVID-19 patients with mild to severe respiratory infections. Interested clinical teams can submit their projects to this website: www.landing.maunakeatech.com/covid19. ....
