Although treatment with anti-IL-7Rα mAb significantly suppressed the expansion of the abdominal aorta in mice treated with PPE (0.89 ± 0.30 mm vs. 1.32 ± 0.38 mm, Fig. 1A and B), it did not affect the incidence of AAA or the survival rates of mice with AAAs. The gene discussed is IL7R; the disease is triple-A syndrome.
