IL‐2 is a T cell growth and survival factor that promotes differentiation of the memory T cell phenotype.28 In T‐cell lines, IL‐2 was shown to interfere with the GC receptor (GR) nuclear translocation, reducing signaling29 and to inhibit GC‐induced apoptosis.30 Single nucleotide polymorphisms in IL‐2 and the IL‐2R are associated with asthma severity,31 suggesting the strength of the IL‐2 pathway may regulate GC responsiveness. This evidence concerns the gene IL2 and asthma.
