Abstract

Introduction

Small ruminant lentivirus (SRLV) infections occur worldwide in goats and sheep and have negative impact on the production and welfare of animals. During recent years, many studies have focused on the host factors that determine the resistance of individual animals to SRLV infection; consideration of such factors would be an alternative to current control programmes based on culling seropositive animals. The aim of this study was to analyse the relationship between the expression of two previously selected goat genes, TMEM154 encoding transmembrane protein 154 and PARP14 encoding poly ADP-ribose polymerase 14, and the kinetics of SRLV replication in primary skin cells of goats. Potential role of these genes as host factors determining susceptibility to SRLV infection was investigated.

Material and Methods

Primary fibroblast cultures obtained from the skin of goats with high SRLV proviral DNA load (HPL), low proviral load (LPL) or free of infection were inoculated with the A5 SRLV subtype circulating in the flock. The course of infection was observed based on cytopathic changes in cell cultures and the presence of SRLV A5 RNA, of which the level was monitored using a quantitative reverse-transcription PCR. The relative expression of the selected host genes following SRLV infection was analysed.

Results

The kinetics of SRLV replication differed, and distinctly higher numbers of SRLV particles were detected in cells derived from the HPL animal. The expression profiles of TMEM154 and PARP14 after in vitro SRLV infection also differed in skin cells derived from HPL from the profiles in LPL-animal cells.

Conclusion

The observed relationship between expression of TMEM154 and PARP14 and cell permissiveness after SRLV infection suggest their involvement in the infection process, but their utility as susceptibility factors still needs to be verified.
