CXCL8 and asthma: In the present study, we focused on ETV4 for a candidate gene association study of asthma, as ETV4 has been recently identified to be among the transcription factors that regulate multi-gene expression-based asthma biomarkers and increase the expression of IL6 and IL8 following stimulation with poly(I:C) in a nasal epithelial cell line model1.
