IL17A and COVID-19: These crossover genes are predominantly enriched in the cellular biogenic amine catabolic process, amine catabolic process, negative regulation of immune system process, cytokine receptor binding, TNF signaling pathway, IL-17 signaling pathway, NF-kappa B signaling pathway, etc. We can roughly divide these terms into modules of inflammatory-immune responses, catabolic process, and other events, which might play a non-neglected role in the association of COVID-19 on UTI.
