近期研究主題

(一)副溶血弧菌 (Vibrio parahaemolyticus) PirAvp 和 PirBvp 毒素結構。

利用蛋白質體學方法 (諸如等溫滴定量熱法、凝膠過濾分析、交聯質譜分析、氫-氘交換質譜分析等),推論 PirAvp 與 PirBvp 毒素間可能的結合比例、親合力以及兩者間可能的結合介面,並基於上述結果提出此二元毒素複合物的異四聚體模型,以推論蛋白質構形變化如何激活 PirBvp N 端成孔功能域的可能機制。未來將繼續探討其他因素對於 PirAvp/PirBvp 複合體穩定度與結構的影響,以期協助未來設計有效的抗 AHPND 策略。

(二)副溶血性弧菌 PirAvp 和 PirBvp 毒素的基因調控。

PirAvp 與 PirBvp 毒素為造成 AHPND 之主要因子,然而,其基因調控機制目前未明。哈維氏進化枝 (Harveyi clade) 的弧菌物種中,包括哈維氏菌 (V. harveyi) 與霍亂弧菌 (V. cholerae),已知有群聚感應 (quorum sensing) 系統,可隨族群密度調控其基因表現,控制諸如生物膜形成、抗藥性、生物發光、質體傳遞、細菌接合作用,以及毒力因子 (包括 T3SS、T6SS、TDH) 的生成等等。而在副溶血弧菌的基因組中同樣也具有高度保守的完整系統,初步試驗結果顯示與 PirAvp、PirBvp 表現有關聯,現階段正探討群聚感應系統對 PirAvp、PirBvp 基因調控的可能機制。

(三)造成白蝦極高致死率之未知弧菌菌株之分析。

目前已有越來越多的弧菌物種被發現會引發 AHPND,或是攜帶含有不同變異的 pVA1-like 質體,並產生不同之毒性。本中心於發生大量蝦隻死亡之畜養池中分離出不同於副溶血弧菌之菌種,其代表菌株可引發白蝦極高死亡率,且該菌株中亦攜帶具有變異之 pVA1-like 質體。研究針對菌種鑑定、毒性蛋白質表現、基因結構等進行分析,以期釐清此高威脅性新菌株之致病機制。
