This IL-5 concentration is presumably low, since it does not result in significant expression of the mAb24 and CBRM1/5 epitopes in fully activated αMβ2; and the IL-5 concentration in the blood of subjects with asthma is only 1–10 pg/ml (0.04–0.4 pM) (Mastalerz et al., 2001; Joseph et al., 2004; Johnsson et al., 2011). This evidence concerns the gene IL5 and asthma.
