New Study shows how Diabetes Injures Nerves

In a new study soon to be published in the FASEB Journal, PNR&D scientist Gina Leinninger reports her newest results on neuronal survival in the face of high glucose. Ms. Leinninger, a current University of Michigan Graduate Student in the Neuroscience Program, has found that Insulin-like Growth Factor I (IGF-I) enhances the survival of those neurons affected in diabetic neuropathy using a specific survival pathway. Cells use this pathway to increase production of a group of factors that protect the cell from glucose-induced damage and death. This increased understanding of both how glucose kills neurons and the factors needed to protect them could lead to the identification of therapeutic targets in the future.

Researcher Outlines New Way to Study Nerve Cells

PFUND researcher Joseph M. Corey, MD, Ph.D., has recent data suggesting that engineered synthetic materials produced in a specific pattern enhance the growth, shape, and migration of neurons and their processes. During spinal cord injury, neurons are damaged or killed. In order for a patient to regain function, the neurons must grow and connect with one another in a particular pattern. Scaffolds are used to aid in proper neuronal growth and connection. Dr. Corey’s results suggest that the material used and the patterns the materials are placed in determine how the neurons will behave. These results further our understanding of how these materials can be used to control the direction a neuron will grow or move in and the connections it will make with other neurons, which will be important for patient rehabilitation after spinal cord injury.

Dr. Rubin Goes the Distance for ALS Research

Dr. RubinDr. Adam D. Rubin has seen the destructive effects of ALS, more commonly known as Lou Gehrig’s disease, both personally and professionally. So it makes sense that the 44-year-old laryngologist would blend his love of running with his desire to find a cure for this devastating disease.

That is why Dr. Rubin planned to run his first New York City Marathon on Nov. 4 to raise funds for ALS research. And while the run was canceled following Hurricane Sandy, Dr. Rubin is continuing to fundraise and will run the Anthem Richmond marathon on Nov. 10 in Virginia.

Donations will go to the Program for Neurology Research & Discovery (PNRD) at the University of Michigan Health System, a laboratory directed by Dr. Eva Feldman with which Dr. Rubin has been affiliated for years.

U-M oversees cutting-edge trial that offers hope in fight against Lou Gehrig’s disease

Sometimes she glares at the painting of Jesus in her dining room.

“I just let it loose,” said Mary Kleiss at her Royal Oak home. “I look at that picture and I say, ‘You get down here and put on your boxing gloves and let’s get this over with.’ I am so damned angry.”

Her son, Regis, was diagnosed two and a half years ago with Lou Gehrig’s disease — amyotrophic lateral sclerosis, or ALS. It is, he writes, “as if God is torturing me.”

The disease kills with stunning efficiency — deadening its victims’ peripheral nerves, withering muscles and, in a final assault, shutting down their ability to breathe. An estimated 30,000 people have it at any given time; 5,000 are diagnosed yearly. Most die within years. There is no cure.
