Type 1 Diabetes: A Treatment’s In Sight?

A Leader in Immunogenetics

Untitled-30McGowan Institute for Regenerative Medicine faculty member Massimo Trucco, MD, is an international leader in the field of immunogenetics, having dedicated his life’s work to finding a cure for diabetes. Dr. Trucco is the Director of the Division of Immunogenetics at the Children’s Hospital of Pittsburgh of the University of Pittsburgh Medical Center, the Hillman Professor of Pediatric Immunology at Children’s Hospital, and a Professor of Pediatrics at the University of Pittsburgh School of Medicine.

Dr. Trucco and his team are closing in on a cure for Type 1 diabetes. He has made several significant findings including the isolation of a super-antigen that is believed to trigger juvenile diabetes in children. It is widely suspected that this discovery, and others that Dr. Trucco has made, will lead to a cure.

A Career Dedicated to Diabetes Research

Type 1 diabetes is regarded as an autoimmune disease because a person’s immune system’s T-cells attack and destroy the beta cells in the pancreas that produce insulin. Type 1 diabetes also is known as insulin-dependent diabetes mellitus or juvenile-onset diabetes. The Centers for Disease Control and Prevention (CDC) and the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)-funded SEARCH for Diabetes in Youth Study reports that 1 of every 523 youth had physician diagnosed diabetes in 2001 (this number included both Type 1 and Type 2 diabetes). SEARCH also found that about 15,000 youth are diagnosed with Type 1 diabetes each year.

Building on his 1994 discovery that Type 1 diabetes susceptibility may be genetic in nature and triggered by viruses, Dr. Trucco’s discoveries have continued to lead to better processes for molecular typing for matching bone marrow donors and recipients, the ability to identify those at risk for diabetes, an understanding of the link between a common virus and Type 1 diabetes, and a potential cure for the pancreatic damage that causes insulin dependence. The research milestones of Dr. Trucco include:

In 1977-78, research into why some organ transplants were successful and why some were not, as well as why all donors and recipients were not compatible, showed that abnormalities in HLA cells (histocompatibility locus antigens) were a genetic predisposition for autoimmune disease.
In 1988-90, landmark studies were published on the genetic susceptibility of certain individuals to Type 1 diabetes. Research also showed that the low incidence of diabetes in China is related to that population’s relative genetic resistance to the disease, while the high incidence of diabetes in Finland is related to that population’s genetic predisposition.

In 1998, the Coxsackievirus B is identified as one of the viruses responsible for triggering Type 1 diabetes, making it possible to potentially develop a vaccine.

In 2006, Dr. Trucco’s lab discovered a process using a patient’s own blood, combined with a safe mixture of molecules. With the use of this combination, it is possible to interrupt T-cell and beta cell interaction, which is known to cause diabetes. The team removed dendritic cells from the patient’s own blood, and the cells were mixed with the proteins CD40, CD80, and CD86, and injected back into the patient where it was found that the CD40, 80, and 86 block the process of the T-cell and beta cell interaction.

Dr. Trucco and his team continue their landmark research into improving the prediction of Type 1 diabetes and understanding and managing its complications. “We have some of the best researchers and clinicians in their fields, and it is conceivable that with this concentration of talent, Pittsburgh could be the place where the cure for diabetes is discovered,” says Dr. Trucco.

Recently reported by the Pittsburgh Post-Gazette, today Dr. Trucco needs $7 million to $10 million for a multi-site trial involving 105 people with a recent diagnosis of Type 1 diabetes. He’s considering beginning with 18-year-olds, and if the therapy succeeds, working backward in age to adolescents.

“It would be the first trial in which live cells are used to treat a disease that is not cancer, and we would be dealing with children,” Dr. Trucco said, discussing his desire to see results after decades of research.
A study published in Diabetes describes the advantages in using one’s own genetically engineered dendritic cells to stop the autoimmune cycle that destroys insulin-producing beta cells.

“It is our conviction that the age of personalized cell therapy … has arrived and that Type 1 diabetes could be the first autoimmune disorder to be successfully treated,” the study states.

Dr. Trucco is leading the pack of researchers targeting dendritic cells as the focus of treatment for Type 1 diabetes. The Phase I human clinical trial already has proven the therapy to be safe while raising excitement for success.

“Massimo clearly is the leader in the field, and the only one, to my knowledge, to get approval for a Phase I trial. He has the correct equipment and facilities to do this,” said C. Garrison Fathman, chief of the division of immunology and rheumatology at the Stanford University School of Medicine.

For proposed treatments, he’s leading the research in using adoptive cellular therapy, or modifying the immune system’s effect on certain cells, to treat a disease other than cancer.

The McGowan Institute congratulates Dr. Trucco on all his scientific achievements and thanks are extended to him and his colleagues on behalf of all of the patients that these emerging technologies may one day help.

Regenerative Medicine Summer School

Untitled-34Under the leadership of Bryan Brown, PhD, the McGowan Institute is organizing the first annual Regenerative Medicine Summer School which will be held July 14-18, 2014. The program is designed to provide national and regional students with a week-long didactic and experiential learning experience addressing the science and engineering related to the multidisciplinary field of regenerative medicine.

The target audience is undergraduates, enrolled in a science or engineering program that will have completed their 3rd year of study; exceptional candidates who will have completed their 2nd year of undergraduate study will be considered.


Small Blood Pumps for Small Patients

Untitled-35McGowan Institute for Regenerative Medicine faculty member Peter Wearden, MD, PhD, Surgical Director, Pediatric Heart and Lung Transplantation, and Director, Pediatric Mechanical Cardiopulmonary Support Program, Children’s Hospital of Pittsburgh of UPMC, and Assistant Professor of Cardiothoracic Surgery, University of Pittsburgh School of Medicine, is the co-recipient of a National Institutes of Health National Heart, Lung, and Blood Institute award under its Small Business Innovation Research Program. The project, “Small Blood Pumps for Small Patients,” was granted to VADovations, Inc., a small, Oklahoma-based start-up company working to build a miniature ventricular assist device (VAD), a mechanical blood pump, which is smaller and lighter than ones currently on the market. Trevor Snyder, PhD, vice president of research and development at VADovations, is the project principal investigator and a former Senior Biomedical Engineer at UPMC and Research Assistant at University of Pittsburgh, Department of Bioengineering.

Dr. Wearden is also a member of the research team, the PediaFlow Pediatric VAD Consortium. PediaFlow, which is made of a titanium alloy and is about the size of an AA battery, incorporates innovative mag-lev technology. Blood is drawn through it by means of a high-speed rotor that essentially floats within its housing due to magnetic levitating forces. The rotor geometry, which is designed using state-of-the-art computer models and analyses, pulls oxygenated blood from the left ventricle through the device, returning the blood to the aorta and patient circulation. The flow rate of the PediaFlow can be varied between 0.5 to 1.5 liters per minute, suitable for the very smallest infants to toddlers.

“We believe the PediaFlow will be capable of replacing the heart function of our smallest patients,” explained Dr. Wearden. “Left ventricular assist devices (LVADs) have been very successful in supporting older children and adults as a bridge to eventual heart transplantation, or, in some cases, as a temporary measure that allows the heart to rest and recover. But there currently are no FDA-approved LVADs for babies and toddlers.”

Precise Electronic Drug Release Thanks to Graphene Oxide Nanocomposite Material

Untitled-36McGowan Institute for Regenerative Medicine faculty member Tracy Cui, PhD, an Associate Professor and the Bicentennial Alumni Faculty Fellow, Department of Bioengineering, and researchers at the University of Pittsburgh are reporting the development of a new material based on graphene oxide that can be electrically triggered to release an anti-inflammatory drug on demand. The results of the study were recently reported by the editors of MedGadget.

The graphene oxide nanocomposite had the drug embedded within its scaffolding and then itself embedded inside an electrically conducting polymer pouch. An electrode ran to the polymer, which, when energized with electrical current, released its drug payload in a controlled fashion. The team also showed that the rate of release was linear to the voltage applied and that the graphene oxide can be fashioned in different ways to allow for a variety of options like different payload quantities, rates of release, and maybe even automatic delivery of a drug when a disease biomarker is detected.

The study abstract reads:

On-demand, local delivery of drug molecules to target tissues provides a means for effective drug dosing while reducing the adverse effects of systemic drug delivery. This work explores an electrically controlled drug delivery nanocomposite composed of graphene oxide (GO) deposited inside a conducting polymer scaffold. The nanocomposite is loaded with an anti-inflammatory molecule, dexamethasone, and exhibits favorable electrical properties. In response to voltage stimulation, the nanocomposite releases drug with a linear release profile and a dosage that can be adjusted by altering the magnitude of stimulation. No drug passively diffuses from the composite in the absence of stimulation. In vitro cell culture experiments demonstrate that the released drug retains its bioactivity and that no toxic byproducts leach from the film during electrical stimulation. Decreasing the size and thickness of the GO nanosheets, by means of ultrasonication treatment prior to deposition into the nanocomposite, alters the film morphology, drug load, and release profile, creating an opportunity to fine-tune the properties of the drug delivery system to meet a variety of therapeutic needs. The high level of temporal control and dosage flexibility provided by the electrically controlled GO nanocomposite drug delivery platform make it an exciting candidate for on-demand drug delivery.

Mood-Stabilizing Drug Could Be New Treatment for Inherited Liver Disease

Untitled-37Opening up a can of worms is a good way to start hunting for new drugs, David Perlmutter, MD, physician-in-chief and scientific director, Children’s Hospital of Pittsburgh of UPMC, and a Distinguished Professor and the Vira I. Heinz Endowed Chair, Department of Pediatrics, University of Pittsburgh School of Medicine, and researchers from Children’s Hospital and Pitt’s School of Medicine recommend. In a study published in the Public Library of Science One, they used a primitive worm model to show that a drug typically used to treat agitation in schizophrenia and dementia has potential as a treatment for α-1 antitrypsin (AT) deficiency, an inherited disease that causes severe liver scarring.

In the classic form of AT deficiency, which affects 1 in 3,000 live births, a gene mutation leads to production of an abnormal protein, dubbed ATZ, that unlike its normal counterpart is prone to clumping, explained Dr. Perlmutter.

“These protein aggregates accumulate in liver cells and eventually lead to scarring of the organ or to tumor formation,” Dr. Perlmutter said. “If we could find a drug that slows or stops this process, we might be able to prevent the need for liver transplantation in these patients.”

To find that drug, Dr. Perlmutter’s team worked with Pitt’s Stephen Pak, PhD, assistant professor of pediatrics, and Gary Silverman, MD, PhD, Twenty-five Club Professor of Pediatrics, Cell Biology and Physiology, who developed a model of AT deficiency in Caenorhabditis elegans, or C. elegans, a harmless microscopic worm or nematode typically found in soil. Previous experiments conducted by Drs. Pak and Silverman, in which more than 2,000 compounds were screened, showed that fluphenazine, a drug approved for human use as a mood stabilizer, could reduce ATZ accumulation in the worm, so the team studied it further.

Worms that produce ATZ die sooner than normal ones, which typically have a life span of fewer than 20 days. Those that were exposed to fluphenazine, however, had lower burdens of ATZ and lived more than a day longer that untreated animals. The lifespan of normal worms was unchanged by fluphenazine exposure. The researchers also labeled with fluorescent markers intracellular structures called autophagosomes, which help clear abnormal proteins out of the cell in a process called autophagy. Fluphenazine exposure was associated with a greater presence of autophagosomes, suggesting that increased autophagy led to reduced ATZ accumulation.

Follow-up experiments showed that fluphenazine reduced ATZ accumulation in several mammalian-cell line models of AT deficiency, Dr. Silverman said. The project also reveals the power of the worm model to rapidly screen drug candidates, Dr. Perlmutter noted.
