IL27RA and triple-A syndrome: Interestingly, 86% of mice transplanted with a 90%wt:10%Il27ra−/− mix of BM developed late stages of AAA and some died due to AAA rupture, whereas only 17% of mice transplanted with a 10%wt:90%Il27ra−/− mix of BM developed AAA, arguing for cell autonomous pathogenic role of IL-27R.
