研究興趣與主題
Research interests and topics
致病性微生物在臨床上往往造成許多嚴重的問題,抗藥性菌株的出現及抗藥基因的傳播也使現有抗生素的使用受到限制,增加感染症治療上的困難。本實驗室研究興趣主要包括微生物致病分子機轉、微生物與宿主細胞交互作用機制、開發抗藥性細菌之替代性治療物質或療法,以及環境、腸道正常菌叢與細菌致病之關連等,主要利用分子生物學、細胞學、免疫學、蛋白質表現純化、基因體學及動物實驗等系統性和整合性方法,探討微生物與疾病相關議題,希望將微生物學研究應用於健康醫療產業,發展疾病篩檢、診斷工具、治療藥物或疫苗,希望幫助解決健康醫療實務問題。
我們的主題與方向
1. 微生物致病機轉、致病因子、病原菌與宿主細胞交互作用
找出病原菌重要之致病因子,探討致病因子作用的分子機制及調控網路,以及探討病原菌如何影響宿主細胞之反應及訊息傳遞,藉此了解病原菌致病機轉,未來可應用於設計藥物或疫苗之標的(target)。
2. 抗藥性細菌之替代性治療物質或方法
從中草藥與天然物中開發對抗藥性細菌有殺菌/抑菌潛力之物質,研究天然化合物之抗菌力與機制,針對抗藥性問題嚴重、可使用的藥物有限之臨床致病細菌,分析in vitro抗菌力、作用機制及in vivo動物試驗,進一步探討應用於感染症治療與控制之潛力。
3. 環境微生物、腸道正常菌叢菌株與致病菌之抗藥性分佈、致病力與多樣性
隨著One Health (健康一體、防疫一體)的概念越來越受到重視,認為人類、動物、環境的健康衛生關係是息息相關,這些面向的健康都需要監控與維護以達到疾病預防及緩減。我們希望探討環境、腸道正常菌叢(microflora)與造成感染之微生物之間的關連,藉由分析環境菌株、腸道菌株與感染菌株的特性與基因體,了解其致病力、抗藥性分佈、之間可能的傳播與演化,可應用於評估腸道微生物篩檢或環境檢測。
Our research interests are mainly focusing on pathogenic microbes, mechanisms and their interactions with human and environments. Pathogenic microbes could cause infections and serious problems clinically. Emergence of antibiotic resistance in microbes is a global health crisis and cause public health problems. Studies of microbial pathogens and the underlying mechanisms can be applied to develop new drugs, vaccines or diagnostic tools, which can help for treatment of disease and improvement of human health in the future.
We use multiple approaches to study microbial pathogens. Our research topics are including
1. Microbial pathogenesis (mechanisms) and virulence factors
2. Pathogen-host interactions and molecular details
3. Antimicrobial activities of natural occurring compounds; potent alternative therapeutic agents against drug-resistant bacteria (alternative medicine; complementary medicine)
4. Relationship between enteric bacteria, environments and infections
