TNF and ischemic stroke: KEGG pathway analysis revealed that, when compared with vehicle controls, the top 20 enriched pathways in CPAG‐1‐treated mice were mainly related to inflammation 3 days after ischemic stroke, and included the TNF signaling pathway, NOD‐like receptor signaling pathway, cytokine‐cytokine receptor interaction, and IL‐17 signaling pathway (Figure 5D).
