Moreover, to gain better understanding of IL-19 signaling following SARS-CoV-2 infection, we examined levels of IL-19 heterodimer receptor complex, IL-20R1 and IL-20R2, in SARS-CoV-2 infected AECs, nasopharyngeal swabs and lung autopsies of COVID-19 patients (Fig. 2G–L). The gene discussed is IL20RA; the disease is COVID-19.
