Paul (Kip) Kinchington, Ph. D. heads the Molecular Herpesvirus unit of the Campbell Laboratory of Infectious Diseases in The Department of Ophthalmology. His research addresses viruses that cause ocular complications and potential blindness, particularly Varicella Zoster Virus, the cause of Herpes Zoster (“Shingles”).
Herpes zoster is also known as “shingles”, a debilitating and crippling disease seen mostly in the elderly and in patients whose immunity is weakened by disease, cancer or its treatment. Zoster arises from within us when the human herpesvirus Varicella Zoster Virus (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 us, and a third will get zoster in their lifetime. Zoster can have devastating consequences on vision and well-being, potentially infecting any part of the eye. For example, the cornea may become cloudy and onscure vision. It can also become totally numb, so that one does not sense it when there is damage to the front of the eye. It can also destroy the retina and the means to transmit light to the brain, causing blindness, Finally there are a host of neurological problems that follow zoster that affect how we see, including tics, palsies, uncontrollable eye movements and most important, an intractable, debilitating and difficult-to-treat pain that may last for months to years.
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 model of human neurons, which is allowing us with an unprecedented look at what happens to VZV at the dormant ‘latency’ phase in human nerves. We can now assess what must happen for the virus to reactivate, and seek means to target the mechanisms and keep the virus latent. We use this same system to visualize virus moving along the nerves, which the virus does to reaches the skin and eye (and can be blocked).
A second important development is our new animal models that are allowing us to study how VZV causes pain. The models are enabling us to address the underlying mechanisms, and also the testing of pain alleviating strategies that do not rely on problematic opioids or similar drugs with side effects. Indeed, we now have a potetntial treatment strategy that could potentially allow the patient to tune their own relief by topical treatments. Given that zoster and the associated pain are important diseases of the elderly, and that pain is more likely to be more severe as one ages, 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.
