A new Nanovaccine could reverse type 1 diabetes in mice, according to Canadian researchers. The news raised hope that in the future a similar vaccine containing microscopic immune-system proteins could be developed for humans.
Dr. Pere Santamaria drew links with the vaccine and bodily T cells, the immune system cells that attack insulin-producing cells in the pancreas . The University of Calgary expert was reported as saying: “Essentially, there is an internal tug-of-war between aggressive T cells that want to cause the disease and weaker T cells that want to stop it from occurring”.
The vaccine his team developed expands the number of T cells, which then lowers the incidence of attack by other, more aggressive T cells that would otherwise be destroying insulin producing beta cells .
