In addition to significantly higher NETs in COVID-19(+) TV vs. COVID-19(+) PU skin, COVID-19(+) TV skin also had more intense neutrophil elastase and CD61 staining than COVID-19(+) PU skin, correlating with the known ability of NETs to propagate inflammation and thrombosis (Figure 4D and Supplementary Figure 3). Here, ITGB3 is linked to COVID-19.
