In this study, we established the COVID-19 infection model in cynomolgus macaques (CMs), the differentially expressed proteins was analyzed in lung tissue collected from 3 untreated (NC1-3) and 4 CMs inoculated with SARS-CoV-2 for 7 days (nCoV1-4). The results showed the differentially expressed genes (DEGs) before and after exposure. The median CV values was analyzed to confirm the proteomics data with good degree of consistency and reproducibility (median<0.25). The histogram of GO terms enriched in biological process, cellular component and molecular function.
