Malfunctioning Pancreatic

A malfunction in the pancreas's "circadian clock*," the built-in timer found in all living things that regulates major biological processes, may be one of the reasons that people develop diabetes.

Beware the Perils of Severe Hypoglycemia

Over 80 years ago, famed diabetologist Elliot Joslin said about the treatment of patients with type 1 diabetes: "Ketoacidosis may kill a patient, but frequent hypoglycemic reactions will ruin him."  Unfortunately, hypoglycemia continues to be the most difficult problem facing most patients, families, and caregivers who deal with the management of type 1 diabetes on a daily basis. Frequent hypoglycemia episodes not only can "ruin," or adversely impact the quality of life for patients, but also, when severe, can cause seizures, coma, and even death.

Recruiting Patients with Newly Diagnosed Type 1 Diabetes

Dr. Richard Hays announced today that he is now recruiting children with newly diagnosed type 1 diabetes for Protégé Encore, a randomized, placebo-controlled Phase III clinical trial. This is the second of two Phase III studies testing the safety and efficacy of an investigational drug called teplizumab. The first study, known as Protégé, has completed enrollment of more than 530 subjects with type 1 diabetes. There is currently no approved therapy to slow the progression of type 1 diabetes.

Stem Cell Treatment for Type 1 Diabetes

Osiris Therapeutics announced that it has been granted Orphan Drug designation from the U.S. Food and Drug Administration (FDA) for Prochymal as a treatment for type 1 diabetes mellitus. The FDA instituted the Orphan Drug Act to promote the development of treatments for underserved patient populations. To be eligible for Orphan Drug designation, the treatment must target a disease that affects fewer than 200,000 new patients per year in the United States.

Insulin-Producing Cells Derived from Specially Bred Pigs

NEW YORK, April 27, 2010 - The Juvenile Diabetes Research Foundation announced today that it is partnering with Living Cell Technologies (LCT), a New Zealand-based biotechnology company focused on developing cell based therapeutics, in a Phase II clinical trial to study the safety and effectiveness of transplanting encapsulated insulin-producing cells from pigs as a treatment for type 1 diabetes with significant hypoglycemia unawareness.

Artificial Pancreas for Type 1 Diabetes Works in Clinical Trials

The first human trials of the latest design of an artificial pancreas for people with type 1 diabetes found the device worked without causing low blood sugar (hypoglycemia).

Insulin-Producing Beta Cells Can Be Reborn

Healthy, insulin-producing beta cells in the pancreas have a relatively long life and typically do not replicate under normal conditions. Any loss of beta cells, therefore, is usually permanent. In the case of type 1 diabetes, for example, the destruction of beta cells by the body's own immune system is permanent.

The Story of GAD

You may not have heard of GAD, but it's a hot topic in the world of type 1 diabetes research. GAD, which stands for glutamic acid decarboxylase, is an enzyme in the brain and the pancreas that plays several roles in the body. As an enzyme, it converts the excitatory amino acid glutamate into the inhibitory neurotransmitter GABA, which nerve cells use to communicate.  But it also has a less helpful role, as an autoantigen (an element of self that provokes the generation of antibodies) in autoimmune diabetes.

Discovery of a Suspect Enzyme in Humans Could Lead to Powerful Type 1 Therapy

An enzyme that destroys pancreatic beta cells in lab mice has now been observed in human beta cells. Because scientists already know how to delete the mouse gene that produces the enzyme, they are hopeful that the same therapy can eventually be applied to people with type 1 diabetes. If so, it would be one of the most powerful therapies yet for addressing the destruction of insulin-producing beta cells that causes type 1.

JDRF-Funded Research Advances Potential for Regeneration as a Possible Cure for Type 1 Diabetes

A hormone responsible for the body's stress response is also linked to the growth of insulin-producing cells in the pancreas, according to JDRF- funded researchers at the Salk Institute for Biological Studies in California. The findings are the latest advances to underscore the potential for regeneration as a key component of a possible cure for type 1 diabetes.
