Project description:Analysis of COVID-19 hospitalized patients, with different kind of symptoms, by human rectal swabs collection and 16S sequencing approach.
Project description:The emergence of a new type of COVID-19 patients, who were retested positive after hospital discharge with long-term persistent SARS-CoV-2 infection but without COVID-19 clinical symptoms (hereinafter, LTPPs), poses novel challenges to COVID-19 treatment and prevention. Why was there such a contradictory phenomenon in LTPPs? To explore the mechanism underlying this phenomenon, we performed quantitative proteomic analyses using the sera of 12 LTPPs (Wuhan Pulmonary Hospital), with the longest carrying history of 132 days, and mainly focused on seven LTPPs without hypertension (LTPPs-NH).
Project description:We performed the longitudinal peripheral blood transcriptome profiling after diagnosis in five patients, and found that patients' blood transcriptomes undergo dramatic and consistent changes in early recovery stage (ERS). Meanwhile, the blood transcriptome did not fully return to the healthy state even after more than one month of recovery. We also realized that differential expressed genes (DEGs) are enriched in biological processes of antigen processing and related processes, and promoter regions of these genes enrich key transcription factors (TFs) involved in T cell differentiation and activation. We further provided potential mechanisms underlying these orchestrated processes, by revealing these specific TFs mediated gene co-expression network.
