CPAF is highly conserved among Chlamydia spp. leading us to hypothesize that immunization with rCPAF with IL-12 will protect against high-fat diet (HFD) and C. pneumoniae-induced acceleration of atherosclerosis. rCPAF ± IL-12 immunization induced robust splenic antigen (Ag)-specific IFN-γ and TNF-α production and significantly elevated serum total anti-CPAF Ab, IgG2c, and IgG1 antibody levels compared to mock or IL-12 alone groups.
The current authors have previously reported that exosomes from mature dendritic cells (mDC‑exo) participate in endothelial inflammation and atherosclerosis through membrane tumor necrosis factor‑α mediated the nuclear factor (NF)‑κB signaling pathway.
Biologic inhibitors of tumor necrosis factor-α may be beneficial in preventing cardiovascular disease because tumor necrosis factor-α promotes the initiation and progression of atherosclerosis.
The present study indicated that the mechanism underlying the effects of Tianxiangdan Granule on the prevention and treatment of atherosclerosis may be as follows: Tianxiangdan Granule may decrease the expression of the inflammatory cytokines IL‑1β and TNF‑α, and suppress activation of the NF‑κB p65 and p38 MAPK signaling pathways.
The aim of the present study was to measure the level of microRNA (miRNA or miR)-24 in the serum of patients with atherosclerosis and to investigate the effect of miR-24 on the expression of importin-α3 and tumor necrosis factor (TNF)-α, as well as the proliferation and migration of vascular endothelial cells.
We next studied the expression of TNFα and CCL18 mRNA in lesions corresponding to different stages of atherosclerosis progression and found that it was maximal in lipofibrous plaques that are most enriched in lipids.
This study is that ginsenoside Rb1 exerted an inhibitory effect on early atherosclerosis in ApoE-/- mice via decreasing body weight and food intake daily, upregulating the lipid levels of serum plasma, including those of TC, TG and LDL-C and HDL-C and reducing the atherosclerotic plaque area, suppressing inflammatory cytokines (levels of IL-1β, IL-6 and TNF-α) in the serum of ApoE-/- mice, changing the expression levels of BCL-2, BAX, cleaved caspase-3 and cleaved caspase-9 and weakening apoptosis associated with anti-inflammatory activity.
Tumour necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is increasingly recognised to play a protective role in atherosclerosis, however the molecular mechanisms by which it exerts its beneficial effects are unclear.
In addition, 7,8,4'-THI significantly downregulated TNF-α stimulated the expression of vascular cell adhesion molecule-1 and monocyte chemotactic protein-1 and phosphorylation of IκB kinase and IκBα involved in the initiation of atherosclerosis in HUVECs.
In this report, we evaluate the presence and grade of atherosclerosis in patients with AS, uninterruptedly treated with tumor necrosis factor-α (TNF-α) antagonists for 2 years, in comparison to that in a nontreated group of healthy controls.Fourteen patients with AS and 14 healthy controls underwent carotid sonography to measure intima-media thickness (IMT) and to evaluate the presence of plaque.
Inflammation relevant genes, such as F4/80, tumor necrosis factor (TNF)-α, interleukin (IL)-1, IL-6, and monocyte chemoattractant protein (MCP)-1, and lipid metabolism associated gene, such as LDL receptor, class A scavenger receptors (SR-A), scavenger receptor class B type I (SR-BI), CD36, ATP binding cassette subfamily A member 1 (ABCA1), and ATP binding cassette subfamily G member 1 (ABCG1) in the aorta were significantly down-regulated in miR-217 group when compared with atherosclerosis group.
The increased levels of pro-inflammatory cytokines (IL-6, TNF-α, sVE-cadherin) induced by AS were also decreased by baicalin treatment, indicating that baicalin acted as an anti-inflammation regulator in AS.
Although essential for inflammatory responses, leukocyte recruitment to blood vessel walls in response to inflammatory stimuli, such as TNF-α, can contribute to vascular occlusion in inflammatory diseases, including atherosclerosis.
In this review, we explore the emerging role of tumor necrosis factor receptor-associated factor 6 (TRAF6)-nuclear factor kappa B (NF-κB) signaling axis in atherosclerosis, ischemic heart disease, pathologic cardiac hypertrophy or heart failure, myocarditis, and sepsis-induced cardiomyopathy.
Hyperuricemia and artery atherosclerosis are closely associated and, as a classic inflammatory biomarker, tumor necrosis factor‑α (TNF‑α) has a direct role in atherogenesis.
