Genomic analysis and mRNA expression of equine type I interferon genes.
Abstract: This study aimed at identifying all of the type I interferon (IFN) genes of the horse and at monitoring their expression in equine cells on in vitro induction. We identified 32 putative type I IFN loci on horse chromosome 23 and an unplaced genomic scaffold. A phylogentic analysis characterized these into 8 different type I IFN classes, that is, putative functional genes for 6 IFN-α, 4 IFN-β, 8 IFN-ω (plus 4 pseudogenes), 3 IFN-δ (plus 1 pseudogene), 1 IFN-κ and 1 IFN-ε, plus 1 IFN-ν pseudogene, and 3 loci belonging to what has previously been called IFN-αω. Our analyses indicate that the IFN-αω genes are quite distinct from both IFN-α and IFN-ω, and we refer to this type I IFN as IFN-μ. Results from cell cultures showed that leukocytes readily expressed IFN-α, IFN-β, IFN-δ, IFN-μ, and IFN-ω mRNA on induction with, for example, live virus; while fibroblasts only expressed IFN-β mRNA on stimulation. IFN-κ or IFN-ε expression was not consistently induced in these cell cultures. Thus, the equine type I IFN family comprised 8 classes, 7 of which had putative functional genes, and mRNA expression of 5 was induced in vitro. Moreover, a relatively low number of IFN-α subtypes was found in the horse compared with other eutherian mammals.

The research identifies all equine type I interferon (IFN) genes and monitors their expression in horse cells during in vitro induction. The study found 32 putative type I IFN genes in horses, divided into 8 different classes, and was able to induce mRNA expression of 5 of these classes in vitro.
Identification of Equine Type I IFN Genes
- Through genomic analysis, the study identified 32 putative type I IFN genes in the horse genome.
- These genes were found on horse chromosome 23 and an unplaced genomic scaffold.
- Phylogenetic analysis further divided these genes into 8 different classes, including IFN-α, IFN-β, IFN-ω, IFN-δ, IFN-κ, IFN-ε, IFN-ν and a previously uncharacterized class, tentatively named IFN-μ.
- It’s important to note that some of these were identified as pseudogenes, non-functional segments of DNA that resemble functional genes.
mRNA Expression of Equine Type I IFN Genes in vitro
- The researchers monitored the expression of the IFN genes in horse cells during in vitro induction.
- They found that leukocytes (white blood cells) readily expressed IFN-α, IFN-β, IFN-δ, IFN-μ, and IFN-ω mRNA when induced with live virus.
- In contrast, fibroblasts (cells that produce connective tissue) only consistently expressed IFN-β mRNA on induction. Neither IFN-κ nor IFN-ε expression was consistently induced in these cell cultures.
Comparison with Other Eutherian Mammals
- It was found that the horse has a relatively low number of IFN-α subtypes compared to other eutherian (placental) mammals. This could potentially impact how the horse’s immune system responds to viral infections.
Conclusion
- The research has added to a growing body of knowledge about the molecular biology of the horse’s immune response, which could have implications for understanding and treating diseases in horses.
