KEGG pathway enrichment analysis revealed that STING-interacting proteins during P. gingivalis infection were predominantly enriched in ribosome biogenesis, systemic lupus erythematosus, necroptosis, neutrophil extracellular trap formation, and the PD-L1/PD-1 checkpoint pathway in cancer (Figure 5e). Here, STING1 is linked to systemic lupus erythematosus.
