Outline of Final Research Achievements |
In this study, we analyzed the effects of pre-existing pulmonary hypertension on ARDS using a monocrotaline-induced pulmonary hypertension model. In rats with monocrotaline-induced pulmonary hypertension, some of the inflammatory responses triggered by intratracheal LPS administration were attenuated, and tissue damage was not exacerbated. These findings suggest that in patients with pulmonary hypertension accompanied by inflammation, the immune response in the lungs may be weakened, leading to reduced inflammation but increased susceptibility to infections.

Academic Significance and Societal Importance of the Research Achievements |
本研究では肺高血圧症がARDSに与える影響について動物モデルを用いて研究を行い、炎症を伴う肺高血圧症モデル動物では、病原体によって引き起こされる炎症反応の一部が減弱していることを明らかすることができた。本研究の成果から、肺高血圧症の患者さんが、肺炎などに対して脆弱であるメカニズムの解明につながることが期待される。
