IL4 and congenital rubella syndrome: Although increases in IL-4, IL-5, IL-13, and CCL11 mRNA levels were also detected in the DKO group, they were obviously lower than those in group CRS (IL-4: 1.84 ± 0.36 vs. 3.34 ± 0.93, p = 0.0203; IL-5: 6.68 ± 0.75 vs. 11.67 ± 2.58, p = 0.0100; IL-13: 4.87 ± 2.72 vs. 9.33 ± 2.48, p = 0.0423; CCL11: 4.57 ± 2.36 vs. 9.96 ± 2.72, p = 0.0159, Figure 8A).
