Immune cell profiling of COVID-19 patients in the recovery stage by single-cell sequencing.

ABSTRACT: COVID-19, caused by SARS-CoV-2, has recently affected over 1,200,000 people and killed more than 60,000. The key immune cell subsets change and their states during the course of COVID-19 remain unclear. We sought to comprehensively characterize the transcriptional changes in peripheral blood mononuclear cells during the recovery stage of COVID-19 by single-cell RNA sequencing technique. It was found that T cells decreased remarkably, whereas monocytes increased in patients in the early recovery stage (ERS) of COVID-19. There was an increased ratio of classical CD14⁺⁺ monocytes with high inflammatory gene expression as well as a greater abundance of CD14⁺⁺IL1β⁺ monocytes in the ERS. CD4⁺ T cells and CD8⁺ T cells decreased significantly
