The authors would like to thank Dr. Jay Pepose for helping teaching the model to us. This work was supported by National Institutes of Health Grants EY11885 (PMS), EY21247 (PMS) and an unrestricted grant from Research to Prevent Blindness to Department of Ophthalmology.

Animal Care Note: Analgesics are not used in this model as they are anti-inflammatory and thus would invalidate the model.

The recurrent model of herpetic stromal keratitis (HSK) described here enables the investigator to study human HSK in a model that is more consistent with that which is observed during human disease. Thus, the model's strengths are that disease occurs in the context of an immune system that has already by stimulated during primary disease. Since these mice already have an immune response to HSV-1, the factors that reactivate that immune response are likely different from those that originally generated it. Therefore, the...

recurrent herpetic stromal keratitis in mice, a model for studying human hsk

Herpetic eye disease, termed herpetic stromal keratitis (HSK), is a potentially blinding infection of the cornea that results in over 300,000 clinical visits each year for treatment. Between 1 and 2 percent of those patients with clinical disease will experience loss of vision of the infected cornea. The vast majority of these cases are the result of reactivation of a latent infection by herpes simplex type I virus and not due to acute disease. Interestingly, the acute infection is the model most often used to study this disease. However, it was felt that a recurrent model of HSK would be more reflective of what occurs during clinical disease. The recurrent animal models for HSK have employed both rabbits and mice. The advantage of rabbits is that they experience reactivation from latency absent any known stimulus. That said, it is difficult to explore the role that many immunological factors play in recurrent HSK because the rabbit model does not have the immunological and genetic resources that the mouse has. We chose to use the mouse model for recurrent HSK because it has the advantage of there being many resources available and also we know when reactivation will occur because reactivation is induced by exposure to UV-B light. Thus far, this model has allowed those laboratories using it to define several immunological factors that are important to this disease. It has also allowed us to test both therapeutic and vaccine efficacy.

Recurrent Herpetic Stromal Keratitis in Mice, a Model for Studying Human HSK

Most studies of herpetic corneal disease use a primary infection model. However, primary infection with HSV-1 does not typically lead to human disease. Here we describe a recurrent model of herpetic corneal disease, which more closely mimics human disease.

No entanto, a infecção primária por HSV-1 normalmente não conduzem à doença humana. Aqui nós descrevemos um modelo recorrente de doenças da córnea herpética, que mais imita a doença humana.
