Kip Kinchington, PhD has long been interested in the viruses that cause infections of the eye that can cause blindness.  I started in the Department of Ophthalmology at Pitt at the beginning of 1991, because at that time there was a suspected big breakthrough in understanding how the herpesvirus herpes simplex virus (HSV) might switch between active growth, in which more virus is made and the virus inflicts repeated damage to cause recurrent eye diseases: and a quiet dormant state, in which the virus hides in nerves for the life of the host (also caused latency).  I was a molecular virologist with experience in the much less understood herpesvirus Varicella zoster virus (VZV), which causes potentially devastating diseases of the eye during shingles.  I felt the opportunity was ripe to combine molecular virology with ophthalmology.  In addition to my research on VZV, I have worked on other viruses that cause eye disease, including adenoviruses (which cause infectious pink eye), herpesviruses (causing blinding stromal keratitis and anesthetic corneas), and some RNA viruses in the eye.

I was also excited by the opportunity to collaborate at Pitt.  First with Dr Jerry Gordon, who was studying HSV ocular disease using animal models, who had lots of ideas, but little experience in molecular virology.  Secondly, I would be directing a Molecular Biology core module of the NEI funded CORE grant EY08098 , something I have done now since (for 30 years).  It allowed me to help many other researchers in vision, since the facility provides services and expertise to NEI funded researchers and Investigators. I knew how to manipulate DNA and RNA, make recombinant viruses and /or virus based expression systems, and have continually kept it up-to date so that I and the module can guide vision researchers in the ever-evolving methods, kits and techniques that are used in molecular biology and for transcriptome expression.

My passion with VZV is to understand how it grows to cause eye diseases and the problems associated with Shingles.  I have three different projects.  The first is address why VZV causes the pain and post herpetic neuralgia that often follows a bout of Shingles.  We developed an exciting new facial model that mimics the pain seen in facial shingles that involves the eye, causing ocular pain. We are using it to test new pain relieving treatments.  The second is to understand how the virus infects and co-operates with neurons and nerve cells to stay quiet, and then awaken to cause Shingles. The virus hides in neurons for decades, and then awakens to cause shingles (and eye disease if it’s on the head).  We developed a new cultured human neuron platform to examine how virus spreads and moves up and down neurons to get from the eye to the nerve cell bodies in the ganglia.  We are even testing ways to remove the latent virus from neurons using CRSPR-cas9.  Finally we have projects to investigate why the live virus used in the vaccines are attenuated.  If we know the cause of attenuation, we could improve the vaccines so it does not have the occasional problems associated with current vaccination.

"A rat model for Varicella Zoster Virus induced post herpetic neuralgia” 1-15-2009 to 12-30-2013. The work in this program aims to identify the mechanisms underlying the ability of VZV to induce long term behavioral responses indicative of pain. The project also aims to develop VZV mutants that lack the ability to induce pain, and uses novel viral delivery strategies to suppress the pain induced by VZV.
