Lab Extended Experimental Investigation.
An experimental treatment can essentially reverse type 1 diabetes in certain types of laboratory mice, according to a series of studies led by University of Utah Health scientists. An injection of the therapeutic agent converts cells that normally control glucose production into ones that generate insulin.

The researchers say giving the animals a single dose of a human antibody that suppress the actions of glucagon, a hormone involved in glucose regulation, Exlerimental a remarkable transformation in the pancreas, leading to a nearly 7-fold increase in insulin cell mass and the suppression of diabetic symptoms. However, the researchers caution they are still far from this goal. Glucagon and insulin are produced by groups of cells in the pancreas known as islets https://www.ilfiordicappero.com/custom/college-is-not-for-everyone/advertising-the-goal-of-advertising.php Langerhans.
These hormones work in tandem to keep blood glucose under control.

As a result, most people with type 1 diabetes rely on insulin injections or Lab Extended Experimental Investigation to survive. Danielle Dean, a study co-author and assistant professor of medicine at Vanderbilt University Medical Center. To determine if that can happen, Holland, Dean and colleagues induced diabetes in mice, triggering the death of insulin-producing beta cells in the pancreas. When these same mice were given a human monoclonal antibody called Ab-4 that blocks glucagon binding in the liver, their blood glucose levels normalized and circulating blood levels of insulin were restored. Digging deeper, the researchers tracked glucagon-producing alpha cells using a fluorescent protein marker that glows red. The Lab Extended Experimental Investigation number of glowing red cells were also producing insulin suggesting that these glucagon producing cells had started making insulin instead. These initial studies were performed in mice that were able to regenerate insulin-producing cells without interference from the immune system.
Next, the scientists turned their attention to non-obese diabetic NOD mice. These animals spontaneously develop diabetes because their overly aggressive immune systems readily provoke beta insulin cell death. This condition closely resembles Type 1 diabetes in humans.
However, treatment with Ab-4 restored insulin production and regeneration of abundant numbers of insulin-producing cells in the pancreas. However, many potential therapies that increase beta cell mass in mice fail to have the same effect in human islets or in patients. Lab Extended Experimental Investigation see if they could overcome that, the researchers grafted human islets into immunodeficient, diabetic mice. They then selectively killed mouse beta insulin cells, leaving only the human islets in place. Treating these mice with Ab-4 enhanced glucose control and increased the amount of circulating human insulin in their bloodstreams, confirming a benefit to human islets. These effects were still detectable 40 days following treatment.
Moving forward, the researchers are beginning to investigate how alpha glucagon cells convert into insulin-producing cells and avoid being damaged by the immune system. Source: University of Utah.
