CXCL8 and bronchiectasis: Interestingly, Huang et al. (Huang et al., 2019) found that differentially expressed miR-223-3p and miR-92b-5p were associated with PA colonization in bronchiectasis patients, and their expression levels were significantly correlated with sputum inflammatory biomarker levels (IL-β and IL-8), suggesting that these miRNAs could be biomarkers associated with PA colonization.
