Ultimately, the inflammatory response in monocytes/macrophages is induced by the cascade reaction of these molecules, and inflammatory factors such as interferon-γ (IFN-γ), interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) are released, allowing macrophages and other inflammatory immune cells in aneurysms to exert their biological effects [11]. Here, TNF is linked to aneurysm.
