By performing a comparison analysis, we further found that seven druggable genes of IFNAR2, TYK2, VIPR2, PLEKHA4, PDE4A, P4HA2, and PTGFR were identified to be common targets across three COVID‐19‐relevant cell types of lung MSCs, intestinal tufts, and brain endothelial cells (Figure S38A). The gene discussed is P4HA2; the disease is COVID-19.
