Transcriptomic microarray analysis of BoMac cells after infection with bovine foamy virus

Area of Science:

• Veterinary Virology
• Immunology
• Molecular Biology

Background:

• Bovine foamy virus (BFV) is a widespread cattle infection with poorly understood immune system effects.
• Understanding BFV's impact on host immunity is crucial for cattle health management.

Purpose of the Study:

• To investigate the molecular and cellular responses of bovine macrophages to BFV infection.
• To identify host genes and biological pathways affected by BFV in vitro.

Main Methods:

• Utilized a bovine macrophage cell line (BoMac) for in vitro BFV infection.
• Employed bovine BLOPlus oligo microarrays to analyze transcriptome-wide gene expression changes.
• Confirmed key gene expression alterations using reverse transcription quantitative PCR (RT-qPCR).

Main Results:

• Significant expression changes were observed in 124 genes following BFV infection.
• Enriched biological processes included metabolic and immune system functions, cell communication, transport, and response to stimuli.
• RT-qPCR validated the microarray findings for selected genes.

Conclusions:

• BFV infection induces substantial alterations in the bovine macrophage transcriptome.
• These changes suggest a complex interplay between BFV and host cellular machinery, particularly affecting immune functions.
• Further research is warranted to elucidate the full immunological consequences of BFV in cattle.
