Immunotherapy treatment shown safe in type 1 diabetes clinical trial
A small clinical trial showed an immune system therapy was safe for people with type 1 diabetes, British researchers report.
The immunotherapy also showed signs of helping to keep insulin production steady in people newly diagnosed with the disease, the study authors said. However, because this was a placebo-controlled safety trial, there weren't enough people included to know for sure how well the treatment works.
The therapy is similar to an allergy shot in the way it works, the researchers explained.
"Type 1 diabetes comes about when the immune system inadvertently and irreparably damages beta cells that make insulin," said one of the study's authors, Dr. Mark Peakman. He's a professor of clinical immunology at King's College London in England.
Insulin is a naturally occurring hormone that helps usher the sugar from foods into the body's cells to be used as energy. If the immune system continues to attack the beta cells, which are found in the pancreas, a person with type 1 diabetes will no longer make enough insulin to meet the body's needs. It's at this point that they must take insulin injections or use an insulin pump to replace the lost insulin.
Peakman and his colleagues are trying to stop the attacks on the beta cells.
"We have learned that immune attacks like this can be suppressed by immune cells called T-regs (regulatory T cells)," Peakman said.
When people develop type 1 diabetes, it's likely that they don't have enough of the right type of T-regs or those T-regs aren't working very well. So, the investigators developed a type of treatment called peptide immun Continue reading
