The Environmental Determinants of Diabetes in the Young (TEDDY) study is the largest prospective observational cohort study of newborns with increased genetic risk for Type 1 diabetes (T1D). The TEDDY study operates in U.S. (Colorado, Georgia/Florida and Washington State) and Europe (Finland, Germany and Sweden). TEDDY investigators, including Baylor, have concluded from the data that there is an association between prolonged (1 month or more) enterovirus infection and the development of autoimmunity to the insulin-producing pancreatic beta-cells that precedes T1D.
The TEDDY study follows children at high genetic risk for T1D from birth to 15 years of age at six (6) sites across the U.S. and Europe. Appearing this week in the journal Nature Medicine, investigators from Baylor College of Medicine, the University of South Florida, and other institutions have studied samples available in the study database. They have found that by studying the virome, that is, all the viruses in the body they began get an understanding of connections between viruses and the development of autoimmunity against insulin-producing beta cells.
