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 (also known as “shingles”) is a debilitating and crippling disease seen mostly in the elderly and in patients whose immunity is weakened by disease, cancer or treatment. Zoster is not “caught” from someone else, but rather arises from within us when the 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 adults over 30 have VZV within us and a third will get zoster in our lifetimes. Zoster can have devastating effects on vision. It may induce a cloudy cornea that reduces vision: it can destroy the retina and the means to see light at the back of the eye; It may make the cornea totally numb (atrophic cornea), resulting in blinding eye wounds and damage from simple tasks such as applying eye drops: And it can cause a host of drastic neurological problems that affect the eye and means to see. These include 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. Our research is geared to understanding how VZV remains quiet in a person’s nerves for so long (decades), what makes it awaken, and why the virus causes so much pain when it causes zoster. First, we have developed a tissue culture model of human neurons that is allowing us an unprecedented look at what happens to the virus at the dormant ‘latency’ phase in nerves and the factors are that awaken the virus from this state. We have also been able to use this same system to visualize the virus moving along the nerves and understand how it reaches the skin and eye (and can be blocked). Secondly, we have developed a model that is allowing us to address why VZV causes so much pain. This model is not only enabling us to address the mechanisms by which pain is induced, but is also allowing us to test and develop better strategies to treat or even prevent pain associated with zoster. These lines of research could well establish a highly novel approach to treatment that could give long lasting relief to patients with zoster and chronic pain. 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 Director of Molecular Biology facilities in the Department of Ophthalmology, which is an NEI funded and sponsored core facility to aid the programs of all vision researchers in Pittsburgh in cloning, DNA and RNA manipulation, development of vectors to express proteins, and bioinformatics analyses of large datasets assessing gene expression.
