The invention relates to novel polypeptide analogs of GLP-1 and exendin-4. The polypeptide, in a preferred embodiment, is insulinotropic and long-acting. Preferably, the polypeptide's insulinotropic effect is comparable to or exceeds the effect of an equimolar amount of GLP-1 or exendin-4. The invention also relates to a method of treating a subject with diabetes, comprising administering to the subject the polypeptide of the invention in an amount that has an insulinotropic effect. The invention also relates to methods of using GLP-1, exendin-4, and polypeptide analogs thereof for neuroprotective and neurotrophic effects.

Disclosed are methods for identifying and isolating a precursor cell. Also, disclosed are methods of increasing insulin synthesis from a pancreatic B-cell. Further, disclosed are methods of improving pancreatic B-cell function. Still further, disclosed are methods of preventing or delaying the onset of a metabolic disease, methods of treating or preventing a metabolic disease in a subject, and to compositions for treating or preventing a metabolic disease in a subject in need of such treatment or prevention.

GLP-1 exendin-4 peptide analogs and uses thereof

The present invention relates to a population of insulin producing cells made by a process comprising contacting non-insulin producing cells with a growth factor selected from the group consisting of GLP-1 or Exendin-4, growth factors having amino acid sequences substantially homologous to GLP-1 or Exendin-4, and fragmets thereof. The present invention also relates to methods of differentiating non-insulin producing cells into insulin producing cells and of enriching a population of cells for insulin-producing cells. The present invention also relates to methods of treating diabetes.
