A recent study identified different inflammation profiles when comparing gingival tissues of bronchiectasis patients having chronic periodontitis, with 7 genes significantly altered in bronchiectasis patients (LTA, LTB, TNFSF4, TNFSF11, TNFSF13, TNFSF13B, and TNFRSF11B) [105]. This evidence concerns the gene TNFSF13 and bronchiectasis.
