Furthermore, patients with AD showed a significantly higher expression of IL-13 (2.06 × 10−4 [4.53 × 10−5; 6.47 × 10−4], p < 0.05), as well as IL-13RA1 (1.28 × 10−2 [9.92 × 10−3; 2.73 × 10−2], p < 0.005) and IL-13RA2 (4.45 × 10−4 [2.81 × 10−4; 1.21 × 10−3], p < 0.001), compared to HC (IL-13: 2.44 × 10−5 [2.36 × 10−5; 2.58 × 10−5], IL-13RA1: 2.79 × 10−3 [2.43 × 10−3; 3.74 × 10−3], IL-13RA2: 1.35 × 10−4 [1.05 × 10−4; 1.70 × 10−4]). Here, IL13RA1 is linked to Alzheimer disease.
