Type 1 diabetes triggered by lazy T-cells

A research team led by Dr. Ciriaco A. Piccirillo of McGill University's Department of Microbiology and Immunology has discovered that in some individuals, the specialized immunoregulatory T-cells that regulate the body's autoimmune reactions may lose their effectiveness and become "lazy" over time, leading to the onset of type 1 diabetes.
