Furthermore, soluble P-selectin levels in COVID-19 patients were positively correlated with markers of neutrophil activation, i.e., CD11b expression (Fig. 4c) and LTB4 (Fig. 4d), as well as the circulating levels of JAM-C (Fig. 4e) and the percentage of rTEM neutrophils (Fig. 4f). The gene discussed is JAM3; the disease is COVID-19.
