What is herpes keratitis?
Herpes keratitis is an infection of the cornea caused by the herpes simplex virus, leading to severe vision impairment.
Why use an ex vivo model?
Ex vivo models provide a more accurate representation of human disease compared to traditional cell cultures.
What are the advantages of using corneas from human donors?
Human donor corneas allow for the study of disease processes in a system that closely resembles human physiology.
How does this model compare to traditional methods?
This model offers improved relevance and insights into the pathology of viral infections compared to mono-culture systems.
Can this model be used for other diseases?
Yes, the ex vivo corneal model can be adapted to study various diseases affecting the cornea.
