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]. The gene discussed is TNFSF4; the disease is bronchiectasis.
