[주요연구내용]
최근 이슈가 되는 미생물의 항생제내성 (antibiotic resistance)과 군집행동특성 (multicellularity behavior)으로 인해, 임상 및 산업환경에서 기존 항생제를 대체하는 신개념의 세균제어 방식에 대한 필요성이 증대되었으며, 병원성 세균의 독력인자 (virulence factors)를 제어하는 항독력제 (antipathogenics) 및 천적 요법인 파아지 (therapeutic phage/biocontrol) 연구가 주요한 대안으로 떠오르고 있습니다.
약학대학 바이오항생제 연구실 (Lab of Bioantibacterials)에서는 항생제다재내성 법정관리세균으로 고시된 녹농균 (Pseudomonas aeruginosa) 및 주요 병원세균을 대상으로, 독력인자인 산화환원반응회로 (redox response network)와 군집운동성(group behavior), 파아지 및 파아지 소재를 기반으로 바이오항생제 및 바이오항독력제를 개발하기 위한 기초 및 응용 연구를 수행하고 있습니다.
특히, 파아지-세균-숙주의 상호작용을 통합적으로 관찰할 수 있는 녹농균의 초파리 (Drosophila melanogaster) 감염 및 파아지 주입 모델을 구축하여 적은 양의 세균과 약물 및 파아지를 이용하여 다양한 연구를 수행할 수 있는 기반을 마련하고 있습니다.
