William
H. Frey II, PhD
Director of the Alzheimer's Research Center at Regions Hospital in Saint
Paul, MN
Professor of Pharmaceutics
at the University of Minnesota
Consultant to the pharmaceutical and biotechnology industry.
Research Interests
Dr. Frey's patents, owned by Chiron Corporation and the HealthPartners
Research Foundation, target noninvasive delivery of therapeutic and diagnostic
agents to the brain and spinal cord for treating neurologic and psychiatric
disorders and the use of antioxidants to treat and prevent disease. Dr.
Frey has been interviewed on Walter Cronkite's "Universe," the
"Today Show, " "Good Morning America," "20/20,"
"All Things Considered," and on many other shows in the US and
abroad. Articles about Dr. Frey's research have appeared in the Wall Street
Journal, The New York Times, Forbes, US News and World Report, the New
Scientist and numerous other magazines and newspapers. Dr. Frey earned
his BA in Chemistry at Washington University and PhD in Biochemistry at
Case Western Reserve University.
Dr. Frey has discovered a novel,
noninvasive, intranasal method of delivering therapeutic agents, including
neurotrophic factors, to the brain along the olfactory and trigeminal
neural pathways. US patents have been granted for this method of delivery,
which bypasses the blood-brain barrier and should improve the treatment
and prevention of Alzheimer's disease, stroke, multiple sclerosis, Parkinson's,
head and spinal cord injury and other central nervous system disorders.
We have shown that noninvasive intranasal delivery of insulin-like growth
factor or the antioxidant myricetin to the brains of animals with stroke
can dramatically reduce brain damage and improve neurologic function.
We are now collaborating with interested pharmaceutical companies to use
this new method of drug delivery to treat central nervous system disorders.
An endogenous irreversible
inhibitor of agonist and antagonist binding to the muscarinic receptor
in human brain has been discovered. This inhibitor is elevated three-fold
in Alzheimer's brain. Loss of receptor function in aging and Alzheimer's
disease is thought to contribute to loss of memory and cognitive fucnction
and to iinterfere with cholinergic therapies. We have demonstrated that
pyrophosphate analogs and natural bioflavonoid antioxidants can prevent
this inactivation and receptor loss. This research utilizes our human
brain tissue depositorym, which contains over 2000 specimens.
