The following appeared in the Oct 3rd 1994 issue of the Durham
North Carolina Herald-Sun (Slightly abbreviated):
 
"Two studies involving the UNC medical school provide evidence that
gene therapy may help patients with Parkinson's Disease and a blood
disorder called Fanconi Anemia.
 
The studies are reported in the Oct.`93 issues of Nature Genetics and
the Journal of Clinical Investigation respectively.
 
Our study of Parkinson's Disease is the first demonstration that gene
therapy with adeno-associated virus safely can transfer and then express
a normal gene to the brain. This is a new delivery approach to gene transfer
in the central nervous system" said R. Jude Samulski, director of the UNC
at Chapel Hill Gene Therapy Center and associate prof. of Pharmacology.
 
Samulski is a member of the Lineberger Comprehensive Cancer Center and the
Program in Molecular Biology and Biotechnology.

Gene therapy is a form of molecular surgery in which a normally functioning
gene is placed into cells with a defective gene, Samulski said. Viruses
have been the main tool used to replace defective genes. `Using (adeno-
associated virus) to carry properly functioning genes to replace mal-
functioning ones has potential for numerous deseases, not just these two',
Samulski said. `Unlike many institutions that are concentrating on using
a specific viral carrier to treat or potentially cure one disease, we are
studying (adeno-associated virus) for use in many different diseases that
could be amenable to gene therapy.'
 
Adeno-associated virus has the potential to replace a defective gene for
the life of a person. It is safe to use, does not cause disease on its
own and can enter dividing and non-dividing cells.
 
Samulski and colleages demonstrated that L-dopamine, a neurotransmitter
that is diminished in PD was produced in a rat model of the disease after
administering adeno-associated virus.
 
`Compared to a group of control animals, the rats given (adeno-associated
virus) had significant behavioral improvement,' he said. When using adeno-
associated virus as a viral carrier for human genes, all of the adeno-
associated virus genes were removed and replaced with a gene that causes
cells to produce L-dopamine when a specific protein is present."
 
A phone call was made to Professor Samulski by Crayton Thompson, one of the
leaders of the Raleigh NC PD Support Group. Samulski indicated they may
ready for human trials in a year or two. They are working with monkeys at
the present time. The NIH, FDA, etc. will review the monkey data and
decide when human trials can begin.
