The Establishment of the Molecular Detecting Techniques for Porcine Endogenous Retrovirus

豬內源性反轉錄病毒分子檢測技術之建立

摘要


近年來報導發現豬內源性反轉錄病毒對於人類細胞具有傳染性,為解決此一隱憂,建立一系列高專一性、高敏感度之檢測技術乃早期診斷及流行病學研究當務之急。本研究根據先前選殖出之豬肉源性反轉錄病害標準病毒株之功能性酵素區域(pol)及殼蛋白區域(gag)設計開發聚合酶連鎖反應檢測技術;亦針對外套膜區域(env)建立適當引子及反應條件可辨別此病毒之A,B,C三種亞型。另建立粒線體核酸檢測以作為豬細胞之標幟序列。此檢測系統未來除了可應用於豬隻來源醫材及醫藥用蛋白質之檢測外,亦可提供臨床醫師追蹤檢測病患之用。

The incidence of porcine endogenous retrovirus (PERV) infecting human cells in vitro has heightened safety concerns over the transmission of PERV to xenograft recipients, making the establishment of diagnostic tests to closely monitor PERV of priority concern. This study detects PERV pol and gag sequences by designing highly specific polymerase chain reaction (PCR) assays with conserved primers. Three sets of primers for the env region are designed to identify A, B, and C subtypes of PERV, and a PCR assay is developed to detect a specific mitochondria sequence as a pig cell marker. These tests allow clinicians to effectively monitor PERV transmission in the serum, cell, or excretion fluid associated with the use of porcine source materials.
