Paul (Kip) Kinchington, Ph. D. heads the ‘Molecular Herpesvirus’ section of the Campbell Laboratory of Infectious Diseases in The Department of Ophthalmology. His research addresses viruses that cause eye infections, particularly Varicella Zoster Virus (VZV), the cause of Herpes Zoster (“Shingles”), and herpes simplex virus (HSV-1).
Dr Kinchington is recognized as a world expert on VZV and the diseases it causes. The importance to vision comes from “Shingles”, a debilitating and crippling disease that is most often seen in the elderly and in patients whose immunity is weakened by disease, cancer or its treatment. The disease arises from within, when VZV awakens from a quiet “latent” state that was established in a person’s sensory nerves during the childhood disease, “chickenpox”. Most people over 30 years old have VZV within them and a third will get zoster in their lifetime. It can have devastating consequences to vision when it occurs on the head. The eye becomes infected and the diseases that develop can be blinding. The cornea may become cloudy and obscure vision: it can also become totally numb, so that it does not sense touch or damage to the cornea. VZV can also destroy the retina quickly, or set up a painful inflammatory disease that can last months to years. Last but not least, a host of neurological problems can develop that reduce quality of life and how we see, including tics, palsies, uncontrollable eye movements and an intractable, debilitating and difficult-to-treat pain.
Our group is one of only a few in the world that study VZV and its biology. The goals of our research are to understanding how VZV remains quiet in a person’s nerves for so long after chickenpox (usually decades), what makes the virus awaken and how the virus causes chronic, long lasting pain after zoster. A huge step to studying these was our development of cultured human neurons, which allowing us to take an unprecedented look at the silent dormant state in human nerves. We can now assess the events that lead to virus reawakening. We are targeting those underlying mechanisms and keep the virus latent to zoster does not develop. We use this same system to visualize virus moving along the nerve axons, which virus must do to reach and infect the eye.
A second important development is our new animal models that are allowing us to study how VZV causes pain. These are being used to test new anti-pain strategies that do not rely on problematic opioids or drugs with serious side effects. Indeed, we now have a potential treatment strategy that could allow the patient to tune their own relief by topical treatments. Our work could improve the quality of life of many patients that reach their twilight years.
Dr. Kinchington is also the Director of a Molecular Biology Core facility in the Department of Ophthalmology, which has long been supported by the National Eye Institute. This allows all vision researchers in Pittsburgh to use molecular biology applications and DNA/RNA manipulation in their research.
