TNF and COVID-19: IL6 participated in multiple inflammation-related pathways such as the cytokine receptor interaction, TNF signaling pathway, JAK-STAT signaling pathway, NF-κB signaling pathway, etc. We analyzed IL6 and hsTnI levels simultaneously in 267 patients with COVID-19 and found that the level of IL6 in COVID-19 patients with myocardial injury was higher than that in patients without myocardial injury.
