RNAseq is a valuable tool that can aid researchers in uncovering the transcriptional changes that occur when a viral pathogen infects a host cell. Viral infection will invariably cause differential expression of many genes, from transcription of mRNA to alternative splicing and degradation. This change in gene expression can be a result of immune activation or a direct activity of the virus to alter the host cell's environment to make it more favorable for viral replication. Studying the innate immune response to a pathogen can reveal which cellular pathways are active, indicating the steps that the host takes to halt viral infection, and detecting virus-mediated mRNA expression changes can help with identifying the pathways which may be exploited by the virus. Gene expression changes-both cell-caused and virus-caused-can be studied through RNAseq, helping to provide a clearer picture of the cellular changes that occur during viral infection. In this protocol, we outline methods to carry out mRNA sequencing in Rift Valley fever virus-infected cell cultures, from infection to library prep and analysis.
