Hypothesis
Equine major histocompatibility complex (MHC) class I molecules act as entry receptors for equine herpesvirus-1 (EHV-1).
Conclusion
Equine MHC class I molecules are essential for EHV-1 entry into equine cells, including CNS endothelial cells.
Supporting Evidence
- Equine MHC class I molecules were shown to bind to EHV-1 glycoprotein D.
- Blocking MHC class I with antibodies significantly inhibited EHV-1 entry into equine cells.
- Knockdown of β2m reduced MHC class I expression and EHV-1 susceptibility in equine dermal cells.
- NIH3T3 cells expressing equine MHC class I became susceptible to EHV-1 infection.
Takeaway
The study found that a part of the horse's immune system helps the EHV-1 virus get into cells, which is important for understanding how the virus spreads.
Methodology
Functional cloning using an equine brain microvascular endothelial cell cDNA library and flow cytometry to assess viral entry.
Limitations
The study primarily focused on equine cells and may not fully represent the mechanisms in other species.
Participant Demographics
Equine cells, specifically equine brain microvascular endothelial cells and equine dermal fibroblast cells.
