Network analysis and protein-protein interactions showed that the GL’s key targets for COVID-19 may include the intercellular cell adhesion molecule-1 (ICAM1), matrix metalloproteinase-9 (MMP9), toll-like receptor 2 (TLR2), and suppressor of cytokine signaling 3 (SOCS3), and the inflammatory cytokine signals, growth factor receptor signaling, and complement system were the crucial pathways by pathway enrichment analysis [42]. Here, MMP9 is linked to COVID-19.
