摘要
NECTIN4是犬瘟热病毒的受体之一。通过在牛肾MDBK细胞株中表达NECTIN4,建立MDBK-N4细胞株用于培养犬瘟热病毒。接种犬瘟热病毒后,MDBK-N4细胞能够扩增病毒并产生细胞病变,这说明病毒受体的表达增强了病毒与细胞膜表面的结合能力,进而改变细胞对病毒的敏感性。这一发现为工业疫苗生产细胞株的开发提供了新的思路。
Nectin cell adhesion molecule 4(NECTIN4) is one of the receptors for canine distemper virus(CDV). In this study, a Madin-Darby Bovine Kidney(MDBK) cell line expressing canine NECTIN4, designated MDBK-N4, was established for CDV culture. We found that MDBK-N4 cell line could multiply the virus and it was caused typical cytopathic effect(CPE) after CDV inoculation, which demonstrated that transfection with viral receptor complementary DNA may enables a non-susceptible cell line to bind virus, support virus replication and develop CPE. Viral receptors expression provides a new way to develop a cell line for vaccine production in industry.
