It is known that Bcl‐XL is expressed in eosinophils and contributes to the pro‐survival function of IL‐5 and GM‐CSF,36, 59 and is transcriptionally regulated by SRF.46 Bcl‐XL mRNA expression is upregulated in eosinophils from atopic dermatitis patients in comparison to eosinophils from healthy controls.31 Therefore, our finding supports the significance of Bcl‐XL in enhanced eosinophils survival. The gene discussed is SRF; the disease is atopic eczema.
