Summary
Bovine viral diarrhoea virus (BVDV) evades host immunity by altering metabolism and downregulating antiviral genes. This study reveals key host responses to BVDV, offering insights into viral persistence and host-pathogen interactions.
Area of Science:
- Veterinary Virology
- Immunology
- Molecular Biology
Background:
- Bovine viral diarrhoea virus (BVDV) causes significant economic losses in the cattle industry.
- BVDV employs strategies to persist in hosts and evade innate immunity.
- Understanding BVDV's immune evasion mechanisms is crucial for controlling its spread.
Purpose of the Study:
- To investigate host gene expression changes during BVDV infection.
- To identify host pathways involved in BVDV-host interactions.
- To elucidate mechanisms of BVDV immune evasion.
Main Methods:
- RNA-Sequencing (RNA-Seq) analysis of BVDV-infected MDBK cells at various time points.
- Validation of differentially expressed genes (DEGs) using RT-qPCR.
- Gene Ontology (GO) and KEGG pathway enrichment analyses.
- Protein-protein interaction (PPI) network analysis.
Main Results:
- Identified numerous differentially expressed genes (DEGs) at 2, 6, 12, and 24 hours post-infection.
- BVDV infection upregulated genes involved in lipid metabolism.
- Antiviral genes (ISG15, Mx1, OSA1Y) and complement/coagulation cascade genes were downregulated.
- PPI network analysis revealed potential interactions among DEGs.
Conclusions:
- BVDV infection alters the host's metabolic network.
- Downregulation of antiviral and complement system genes likely contributes to BVDV proliferation.
- Findings provide insights into BVDV-host interaction mechanisms.

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

4.0K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...
