TNF receptor protein levels and receptor localization in murine and human abdominal aortic tissue. (A) Aneurysmal protein levels of TNFR1 and TNFR2 from PPE- induced aneurysm in mice treated with vehicle (saline), ETN (20 mg/kg), or XPro1595 (20 mg/kg) (n = 3–5). Data are shown as mean SEM. A non-significant trend was detected in TNFR1 levels by one-way ANOVA using Bonferroni test for multiple comparisons. (B) Representative distribution of TNFR1 and TNFR2 in the PPE-induced AAA wall after treatment with saline, ETN, or XPro1595 for 14 days (n = 3–5). (C) TNFR1 distribution in unchallenged thoracic murine aorta. (D) Distribution of TNFR1 in human AAA specimens (n = 2) and human ascending aortas (n = 2). Black arrowheads indicate positive stained cells. M, media; Ad, adventitia.
