UB researchers studying myelination are discovering how metabolic diseases like diabetes may cause neuropathy.
BUFFALO, N.Y. — Diabetic neuropathy is one of the most common complications of diabetes. While not life-threatening, it affects millions in the U.S. and elsewhere, and leads to limb amputations if left unchecked. But the reasons why metabolic disease can lead to neuropathy, which is damage to the peripheral nervous system, have never been well-understood.
Now, in a paper published this week online in Proceedings of the National Academy of Sciences, researchers at the Hunter James Kelly Research Institute (HJKRI) at the University at Buffalo report on research that illuminates what causes some kinds of neuropathy and may reveal potentially powerful therapies.

Researchers at the Hunter James Kelly Research Institute (HJKRI) are highlighting the critical role of a metabolic checkpoint kinase pathway in Schwann cells for the formation of myelin sheaths.
“We are encouraged by our findings and think that our discoveries could be exploited to regenerate myelin sheaths and nerve structure to help patients with neurological disorders.”
This pathway, centered around the molecule “mammalian target of rapamycin (mTOR),” is known to play a paramount role in the regulation of cell metabolism, growth and cell division, as well as aging.
Nerve cells talk to each other by transmitting electrical signals along communication cables called axons, which are enwrapped by insulating myelin sheaths. The myelin sheaths produced by Schwann cells keep axons energized and healthy, and they facilitate the propagation of electrical signals by a process known as saltatory conduction.

African Trypanosomes, Krabbe Disease Among Topics
Nadav Weinstock, a fifth-year MD/PhD student, aspires to become a physician-scientist working on developing therapies for rare diseases that affect babies.
During his first two years of medical school, Weinstock became interested in global health and spent time providing medical care at local free health clinics and to underserved remote populations in the Himalayan Mountains of India.
In 2016, he was awarded an F30 fellowship from the NIH for his research on Krabbe Disease.
Weinstock’s presentation was titled “Understanding Krabbe Disease.”

More researchers have identified a critical step in myelination after birth that has significance for treating neurodegenerative diseases like multiple sclerosis (MS).
In MS and similar diseases, myelin — the protective coating that neurons need to function — becomes lost or damaged.
December 7, 2016
UB researchers have identified a critical step in myelination after birth that has significance for treating neurodegenerative diseases like multiple sclerosis, in which myelin is lost or damaged. Myelin is the protective coating that neurons need to function.
The preclinical research, published online in October in the Journal of Neuroscience, concerns oligodendrocytes, the cells that make myelin, and the progenitor cells that are their precursors.
The work involved the study of voltage-operated calcium channels, which are responsible for initiating many physiological functions.
How myelin-making cells mature
“Our findings show that these calcium channels modulate the maturation of oligodendrocytes in the brain after birth,” said Pablo M. Paez, PhD, an assistant professor in the Department of Pharmacology and Toxicology in the Jacobs School of Medicine and Biomedical Sciences at UB and a research scientist with the Hunter James Kelly Research Institute (HJKRI) at UB, where most of the work was done.
“That’s important because it’s possible that the activity of this calcium channel can be manipulated pharmacologically to encourage oligodendrocyte maturation and remyelination after demyelinating episodes in the brain,” he said.

Neuroscientists at the University at Buffalo's Hunter James Kelly Research Institute (HJKRI) and European colleagues have provided proof of principle for how a genetic mutation leads to some neuropathies.
The international team also used a research drug to successfully alleviate the protein synthesis misstep, thereby improving myelin. Myelin is the fatty material that wraps the axons of neurons and allows them to signal effectively.
As a result, a potential new treatment strategy may be on the horizon for patients with a host of neurological disorders that result from misfolded proteins.

A potential new treatment strategy for patients with Charcot-Marie-Tooth disease is on the horizon, thanks to research by neuroscientists now at the University at Buffalo's Hunter James Kelly Research Institute and their colleagues in Italy and England.
The institute is the research arm of the Hunter's Hope Foundation, established in 1997 by Jim Kelly, Buffalo Bills Hall of Fame quarterback, and his wife, Jill, after their infant son Hunter was diagnosed with Krabbe Leukodystrophy, an inherited fatal disorder of the nervous system. Hunter died in 2005 at the age of eight. The institute conducts research on myelin and its related diseases with the goal of developing new ways of understanding and treating conditions such as Krabbe disease and other leukodystrophies.
Charcot-Marie-Tooth or CMT disease, which affects the peripheral nerves, is among the most common of hereditary neurological disorders; it is a disease of myelin and it results from misfolded proteins in cells that produce myelin.

An exchange student investigating the metabolic exchange that occurs between myelin and axons has received an award from the Center for Undergraduate Research and Creative Activities (CURCA).
Shedding Light on Axonal Damage Nunes' research could help scientists design protection for axons in demyelinating disorders like multiple sclerosis. He is studying what happens to axons when the metabolism of its surrounding glial cells is damaged. His research involves eliminating a crucial energy-producing component in myelinating glia. Myelin, made by glial cells, is the fatty sheath surrounding an axon, the part of a neuron that transmits impulses away from the cell body. Scientists believe that myelin cells provide nutrients and energy to neurons.

The mission of the Hunter James Kelly Research Institute (HJKRI) is moving forward with great fervor with the recent arrival of highly regarded neuroscientists Lawrence Wrabetz and Laura Feltri.
Dubbed "physiccian-scientist superstars" by Michael Cain, dean of the School of Medicine and Biomedical Sciences, at the press conference in 2010 announcing the pair's recruitment to UB, Wrabetz is the institute's first director and holds a primary appointment in the Department of Neurology, with a secondary appointment in the Department of Biochemistry; Feltri has a primary appointment in Biochemistry.
The husband-wife research team arrived in Buffalo in late spring from Milan, Italy, with family and laboratories, including 10 research associates-eight of Italian and two of French descents-and 56 lines of transgenic mice.
August 12, 2010
Lawrence Wrabetz, head of the myelin biology unit at San Raffaele Scientific Institute in Milan, Italy, has been appointed director of the Hunter James Kelly Research Institute (HJKRI) at UB.
Laura Feltri, who heads the neuroglia unit at the Italian institute and is Wrabetz's spouse, also has been recruited to the HJKRI, which was established in 2004 by UB and the Hunter's Hope Foundation. Wrabetz and Feltri will begin transitioning their laboratories to Buffalo this fall.
Both are highly regarded neuroscientists with significant backgrounds in basic and translational research on myelin, known as white matter-the sheath protecting brain nerve fibers that is essential for all normal functioning of the nervous system. They will work as a team in the HJKRI, located in UB's New York State Center of Excellence in Bioinformatics and Life Sciences on the Buffalo Niagara Medical Campus in downtown Buffalo.
