Researchers develop the smart Insulin to control Diabetes

The researchers have developed 'smart' insulin that automatically adjusts the amount of blood sugar in the body of people who suffer from Type 1 Diabetes. This will be a breakthrough for patients who are struggle to maintain healthy blood sugar levels everyday.

Type 1 Diabetes occurs when the body's immune system attacks and destroys the pancreatic cells that produce insulin. Insulin is a hormone that helps the glucose metabolism of food, which used the body's cells for fuel.

People with Type 1 Diabetes must frequently check their glucose levels and inject insulin, sometimes several times a day. However, that's not appropriate routines. If Insulin is too little will raise blood sugar levels over time can lead to serious complications, including heart disease, kidney failure and blindness. But if patients with Type 1 Diebetes get too much insulin, they risk a dangerous coma.

"The idea is to get something completely autonomous. So if the patient does not have to check their blood sugar levels. If they can inject insulin in the morning and know that they have enough supplies for the day, it is a best-case scenario. But I guess where the role of the smart insulin generation in response to glucose," said Matthew Webber, a biomedical engineer at the Massachusetts Institute of Technology who helped develop the smart insulin that activate themselves when blood sugar levels rising.

Single injection of long-acting agent binding molecules of glucose circulating in the blood, automatically bring down blood sugar levels when they jumped. Webber said the researchers have conducted a several tests using laboratory pets. Tests showed that the smart insulin working for at least 14 hours, repetitive and automatic lowering blood sugar levels in rats.

The research is published in the Proceedings of the National Academy of Sciences. And the researchers hope the next step will conduct human clinical trials for the first glucose-response insulin. *** [EKA | FROM VARIOUS SOURCES | VOA NEWS]
