TUBB2A and COVID-19: Furthermore, the function enrichment results of the IFI27 and TUBB2A co-expression genes are both consistent with those enrichment results of the dysregulated genes (Figure 3C, D and H–K), suggesting that the two genes may play a critical role in regulating antiviral immunity pathways of the SARS-Cov-2 infection, such as the KEGG pathway responsible for neutrophil extracellular trap (NET) formation that was widely accepted to be contributory to the COVID-19 pathology (23,27–29).
