To go further insight into the involvement of neutrophils in COVID-19 clinical expression, we performed a proteomic analysis of this blood cell type in COVID-19 patients and two non-infected SARS-CoV-2 control groups composed of healthy subjects and ARDS patients hospitalized in intensive care unit (ICU) respectively. All patients were from Guadeloupe and represent a homogeneous population. We have performed a quantitative proteomic study of neutrophiles from French hot spot COVID region, Guadeloupe, confirming the activation of type I IFN pathway and in some target of IFN as TAP proteins, specifically in COVID patients, but not in hospitalized ARDS non-COVID patients and described modification of the NET proteome potentially associated with ARDS.
