Researchers Develop Novel Treatment to Treat Diabetes, Multiple Sclerosis

However, in people with autoimmune disease, these cells somehow escape the checkpoint and the immune system remains in a state of alert, attacking body cells

Researchers have developed a novel and safe treatment for autoimmune diseases including Type-1 diabetes and multiple sclerosis (MS) that arise when the body’s immune cells attack itself.

Current treatments eliminate these misfunctioning immune cells, but also destroy normal, protective immune cells, leaving patients susceptible to immune deficiency and opportunistic infections.

The new approach, by researchers from the University of Utah in the US, targets the misfunctioning immune cells while leaving the normal immune cells in place.

In the study, published in the journal Nature Biomedical Engineering, the team engineered a protein molecule to deplete the misfunctioning PD-1-expressing cells from the body while leaving normal immune cells in place.

“We wanted to target PD-1-expressing cells. Using this method, we may avoid long-term immune deficiency caused by common treatments for autoimmune disease,” said lead author Peng Zhao, from the varsity.

When tested in a mouse model mimicking Type-1 diabetes, the treatment delayed the onset of diabetes.

“We are really taking treatment for autoimmune disease in a new direction,” said Mingnan Chen, Assistant Professor at the varsity.

“To make similar therapeutics for people, we would need to find the anti-human PD-1 antibody, like the anti-mouse PD-1 antibody.

“If we can generate the human version of therapeutics, I think we could make a huge impact in treating autoimmune disease,” Chen said.

In addition, the treatment was also applied to a mouse MS model.

Besides halting the progression of paralysis, the treatment also restored the mice’s ability to walk.

In a normal functioning immune system, the PD-1-expressing cells, including immune cells, contain a mechanism that prevents the cycle from attacking itself.

Cardiovascular Events Cause 58% Deaths Among Diabetics

Fifty-eight percent of deaths among people with type 2 diabetes are due to cardiovascular events, a leading Mexican expert has said.

“Patients who live with this disease have a greater risk of premature death or disability derived from cardiovascular events,” Hector Sanchez Mijangos, President of the Mexican Diabetes Federation, told Efe news.

The specialist said that the high glucose levels associated with diabetes damage blood vessels, resulting in problems with blood pressure and vision, joint pain and other maladies.

Data from the World Health Organization indicate that more 442 million people suffer from type 2 diabetes.

Mexico’s Health Secretariat has found that while roughly 13 million inhabitants of the Aztec nation are living with diabetes, only half of those afflicted know they have the disease.

In 2015 alone, according to Mijangos, there were more than 98,000 premature deaths in Mexico related to diabetes and the average age of those who died was 66.7 years old.

“This is regrettable, because these people could have lived roughly another 15 years,” he said.

According to the 2012 National Health and Nutrition Survey, only 25 percent of Mexicans suffering with diabetes are managing their condition adequately.

That figure illustrates “why our greatest challenge continues to be access and adherence to treatment”, Mijangos said.

To improve treatment options, Mexican health authorities in January issued an approval for the use of canagliflozin, a drug that helps reduce the amount of blood glucose reabsorbed by the kidneys, which in turns causes more glucose to be eliminated through urination.

“With this medicine, a person can lose 100 milligrams of glucose per day as well as about 400 kilocalories (4,000 calories) a day, which also helps with weight loss,” Mijangos said.

The medicine likewise helps lower the amount of sodium in the body and reduce triglyceride levels and blood pressure.

A scientific trial involving more than 10,000 patients worldwide showed that when combined with conventional treatment, canagliflozin can reduce the incidence of cardiovascular events by up to 18 percent. (IANS)
