A study found that the protein tPA protects nerve cells in the brain from death caused by reduced blood flow, leading to two proposed models for its protective effect. Another study identified IL-15 as a potential new target for treating type II refractory celiac disease.

Insulin analogues: What's all the fuss?

A systematic review of insulin analogues found that they have minimal impact on managing type 1 and 2 diabetes, as well as gestational diabetes. However, rapid-acting insulin analogues may be cost-effective for adults with type 1 diabetes. Experts recommend educational programs to manage sugar levels over insulin analogues.

New discovery a step towards better diabetes treatment

Researchers at Uppsala University develop new image analysis methods to study the release of insulin and cAMP in beta cells. The findings show that ATP causes an increase in cAMP concentration, which varies rhythmically and coincides with variations in calcium signals, resulting in pulsatile insulin secretion.

Fat cells send message that aids insulin secretion

Researchers at WashU Medicine found that fat cells release an enzyme called Nampt, which enhances glucose-stimulated insulin secretion from pancreatic beta cells. This discovery could lead to new methods for improving glucose metabolism in type 2 diabetic or insulin-resistant individuals.

Insulin -- in need of some restraint?

Researchers at the Salk Institute found that knocking out the urocortin 3 gene protects mice against high-fat diet's harmful effects by reducing insulin production. This study suggests a new peptide plays a role in insulin secretion, offering potential therapeutic benefits for treating type 2 diabetes.

A non-invasive method for measuring beta cell mass during diabetes

Researchers have developed a non-invasive method to measure beta cell mass in individuals with diabetes using PET-based quantitation of VMAT2 receptors. This approach allows for the estimation of beta cell mass in rats with type 1 diabetes, providing insights into the pathogenesis of diabetes and potential therapeutic interventions.

MicroRNA study points to novel path for treating diabetes

A team of researchers has discovered that microRNA miR-375 regulates insulin secretion, opening up new avenues for understanding and treating diabetes. The study's findings define a biological function for a mammalian microRNA gene and highlight the importance of collaboration between computation and experiment in modern biology.

Mouse model of type 2 diabetes

Researchers have developed a mouse model that replicates the clinical features of type 2 diabetes, enabling studies on pathogenesis and testing of new therapies. The strain of mice, generated by selectively mutating an insulin-like receptor in muscle cells, fully recapitulates the disease's progression.

University of Pittsburgh research may lead to new therapies for diabetes

Researchers at the University of Pittsburgh have developed transgenic mice that overexpress hepatocyte growth factor, leading to increased beta cell proliferation and insulin production. The study suggests that this approach may lead to new therapies for diabetes by enabling islet cells to proliferate and produce insulin more effectively.

The CARDIA Study: Statement from Dr. Claude Lenfant, director, National Heart, Lung, and Blood Institute

The CARDIA Study found that high-fiber diets are associated with lower insulin levels, weight gain, and other cardiovascular disease risk factors in healthy, young black and white adults. The study of nearly 3,000 participants over 10 years revealed a significant inverse association between fiber consumption and CVD risk factors.
