Dr. Trucco's Quest: Find a Vaccine Against Type 1 Diabetes Based on a Patient's Own Blood

Of all the quests that researchers have undertaken in search of a cure or decisive treatment for type 1 diabetes, the search for a vaccine has to be the boldest. But how would you develop such a vaccine, and how would it work?

JDRF-Funded Study Takes First Step Toward Development of Medicines That Can Regenerate Pancreases

Researchers funded by the Juvenile Diabetes Research Foundation have found two chemical compounds that can trigger the growth of insulin-producing beta cells in the pancreas. The discovery could become the basis for medicines designed to regenerate the pancreas in people with type 1 diabetes.

The Cure: The Slow Road to Hope

Talk of a cure has been around forever. Sometimes it seems as if the cure is a constantly receding dream, always ten years away or just around the next corner.

Students Invent a Protective Pouch to Hold Transplanted Beta Cells

A team of five seniors and two freshmen at Johns Hopkins University has devised a little "pouch" to hold microcapsules of beta cells in the portal vein, from which the cells can send out insulin while safely protected inside. It's made by sandwiching a porous cylinder of nylon mesh between two cylindrical metal stents, similar to the ones that are used to keep clogged blood vessels open.

Glucose Triggers the Development of Embryonic Beta Cells

A new study out of London and Paris indicates in the developing embryo, beta cells form in the pancreas in response to the presence of glucose. Glucose triggers a gene called Neurogenin3 to switch on another gene, neuroD, which is critical for the normal development of beta cells. If glucose levels are low, the gene doesn't switch on and the beta cells don't develop.

A New 'Morning-After' Diabetes Shot Stops Beta-Cell Destruction in Adults

Five years ago, when Dana Elias, PhD, first clutched a publication reporting that a synthetic peptide had halted beta-cell destruction in mice that already were showing high blood-glucose levels, she felt a shiver of excitement. She had helped develop the synthetic peptide, called DiaPep277.

What is the C-peptide Test?

The precursor to insulin produced by the pancreas's beta cells is a peptide chain known as proinsulin. Made up of amino acids bound into a u-shape by a connecting polypeptide, proinsulin is stored in beta cells until a glucose load demands the release of insulin. At this point, the connecting molecule is broken off the bottom of the "u"-its shape earning it the moniker C-peptide-freeing the insulin molecule for secretion.
