PRRSV感染对猪肺泡巨噬细胞IFITM3基因转录的影响
EFFECT OF PRRSV INFECTION ON IFITM3 TRANSCRIPTION IN PORCINE ALVEOLAR MACROPHAGES
摘要
Abstract
As an antivirus protein, interferon inducible transmembrane protein 3 (IFITM3) inhibits a broad spectrum of virus infections. In this study, the specific primers were designed based on the genes of IFITM3 and GAPDH to detect IFITM3 expression in PRRSV-infected porcine alveolar macrophages (PAMs). The recombinant plasmids containing the target genes were constructed as a standard control and real time SYBR Green I RT-PCR method was developed for detection of IFITM3 expression. The results showed that the detection limit of this method was 102copies/μL with good linear relationship, specificity, sensitivity and repeatability. Moreover, the variation coefficient of the method was less than 3%. We used this method to detect the IFITM3 mRNA levels in PRRSV-infected PAMs. The results revealed that the IFITM3 mRNA levels showed no significant difference at the early stage of infection but increased significantly at the late stage of infection in PRRSV-infected PAMs as compared with mock-infected PAMs, demonstrating that the changes of IFITM3 mRNA levels in PRRSV-infected PAMs might be related to PRRSV infection as well as immune evasion.关键词
