| Outline of Final Research Achievements |
We studied the role of innate immune responses and its interaction with adaptive immune pathways in chronic inflammatory lung diseases and chronic pulmonary infections.
We found that high mobility group box 1 (HMGB1), one of the damage-associated molecular patterns, is released into the extracellular space during the early stage of an animal model of pulmonary arterial hypertension and contributes to the development of pulmonary arterial hypertension. Dectin-2 contributes to host immunity against mycobacterial infection through the recognition of mannose-capped lipoarabinomannan. Serum B cell activating factor (BAFF) levels were higher in the patients with connective tissue diseases-associated interstitial lung diseases compared to healthy subjects and the patients with idiopathic pulmonary fibrosis or idiopathic nonspecific interstitial pneumonia.
