To supply insights into SARS-CoV-2 infection of numerous human tissues and comprehend the prospective mechanism of SARS-CoV-2 infection, we investigated TMPRSS2 expression in many typical human tissues and SARS-CoV2-infected human tissues. Working with publicly out there datasets, we performed computational analyses of TMPRSS2 expression levels in 30 regular human tissues, and compared them involving males and females and among younger (ages 49 years) and older (ages 49 years) populations in these tissues. We located that TMPRSS2 expression levels were the highest within the prostate, stomach, pancreas, lungs, little intestine, and salivary gland. The TMPRSS2 protein had fairly high expression levels within the parathyroid gland, stomach, tiny intestine, pancreas, kidneys, seminal vesicle, epididymis, and prostate. On the other hand, TMPRSS2 expression levels had been not substantially unique amongst females and males or involving younger and older populations in these tissues. The pathways enriched in TMPRSS2-upregulated pan-tissue were mainly involved in immune, metabolism, cell development and proliferation, stromal signatures, and cancer and also other ailments. Several cytokine genes displayed positive expression correlations with TMPRSS2 in pan-tissue, which includes TNF-, IL-1, IL-2, IL-4, IL-7, IL-8, IL-12, IL18, IFN-, MCP-1, G-CSF, and IP-10. We additional analyzed TMPRSS2 expression levels in nasopharyngeal swabs from SARS-CoV-2-infected individuals. TMPRSS2 expression levels showed no considerable difference between males and females or involving younger and older individuals. Nonetheless, they had been considerably reduced in SARS-CoV-2infected than in wholesome individuals and patients with other viral acute respiratory illnesses. Interestingly, TMPRSS2 expression levels have been positively correlated using the enrichment levels of four immune signatures (B cells, CD8+ T cells, NK cells, and interferon response) in SARS-CoV-2-infected individuals but most likely to become negatively correlated with them.
