La Dieta di 2 Settimane


For researchers, one of the vital irritating issues about sort 1 diabetes is that they haven’t been capable of decide precisely what causes it. We know that the physique’s immune system mistakenly causes T cells within the pancreas to destroy insulin-producing beta cells — however why?

In a groundbreaking article simply revealed within the journal Science Immunology, scientists from Scripps Research, a California-based biomedical analysis facility, mentioned that they’ve discovered a change that causes the immune system to start destroying beta cells. For greater than 5 years, they ran a sequence of experiments on nondiabetic, chubby mice that they judged to be in a prediabetic state. They sequenced T cells from their blood and analyzed the huge quantity of information they collected.

The researchers had been capable of uncover a mechanism that they name the “P9 switch.” The change allowed a specific group of T cells to assault the islet cells. The researchers additionally discovered that the cells turned on by the change lasted a really brief time — the cells initiated a bout of cell destruction after which vanished. The Scripps researchers conjectured that it was as a result of the cells’ lifespans had been so temporary that earlier diabetes researchers had been unable to establish them.

The researchers hypothesize that immune cells containing the P9 change could be detectable solely in those that are within the early phases of growing sort 1 diabetes.

They plan, subsequently, to recruit 30 people who find themselves thought of to be liable to growing the illness and accumulate blood samples to see in the event that they include the P9 change. If they discover blood check can display the presence of the switch-bearing cells, the invention might result in extraordinarily early detection of sort 1 diabetes and thus allow early intervention and even perhaps a technique of blocking the event of the sickness. As analysis staff chief Luc Teyton, MD, PhD, defined, “The translational aspect of this study is what’s most exciting to me. By using single-cell technologies to study the prediabetic phase of disease, we have been able to mechanistically link specific anti-insulin T cells with the autoimmune response seen in type 1 diabetes. And that has given us the confirmation we needed to move into human studies.”
