Research Interest
만성폐쇄성폐질환(chronic obstructive pulmonary disease, COPD)

흡연에 의한 폐의 만성염증성질환인 COPD는 현재 국내 10대 사망요인이며, 2010년에는 세계적으로 사망 및 불구를 유발하는 4위의 질환이 될 것으로 전망하고 있다. 적극적인 금연 운동에도 불구하고 현재까지도 COPD의 유병률 및 사망률은 지속적으로 증가하는 추세이다. 그 이유 중 하나는, COPD 분야에서 지속적인 연구에도 불구하고 아직까지도 COPD의 병인 기전을 잘 이해하지 못하고 있으며, 따라서, 조기 진단(early diagnosis) 및 근치적인 치료(curative therapy)가 전무하다는 것이다. 따라서, 본 연구진은 COPD의 발병기전을 연구하여, 조기 진단 및 근치적 치료를 위한 진단/치료 표적을 탐색하고, 이를 이용하여 새로운 진단/치료법을 개발하고자 노력하고 있다. 최근 본 연구진은, 항콜레스테롤 제제인 simvastatin(HMG-CoA reductase inhibitor)과 당뇨병 치료제인 rosiglitazone(PPAR-g ligand)이 흡연에 의한 COPD의 발병을 효과적으로 억제하는 것을 알아내었다. 또한, 근치적인 치료로서 골수이식에 의한 폐조직 재생도 효과적인 것을 관찰하였다. 현재 본 연구진은 이들 가능성 있는 치료법(potentially therapeutic regimens)의 세포내,외 기전(신호전달계, 특정 유전자의 조절 기전 등)을 연구함으로써 정확한 치료 기전/표적을 밝히고 이를 통해 이상적인 COPD 치료법을 도출하고자 세부 연구를 지속하고 있다. 현재 연구 방향은, 항염증, 조직 재생, 세포고사/세포증식, stem cell, 단백분해 및 세포외 기질 형성, 관련 신호전달계, 발병 및 발병 억제 유전자 스크리닝, 관련 유전자 발현과 조절 등의 기전 연구가 중심이다.
