Figure 1From: A promoter SNP rs4073T>A in the common allele of the interleukin 8 gene is associated with the development of idiopathic pulmonary fibrosis via the IL-8 protein enhancing modeLevels of IL-8 protein of in BAL fluid collected from normal controls and subjects with IPF. NC: normal controls, IPF: Surgical IPF, A: IPF subjects having rs4073 TT alleles, T: IPF subjects having rs4073 AA alleles. Levels of IL-8 protein were normalized with BAL protein concentration.Back to article page
