Deficiency of immunoregulatory indoleamine 2,3-dioxygenase 1in juvenile diabetes.

A defect in indoleamine 2,3-dioxygenase 1 (IDO1), which is responsible for immunoregulatory tryptophan catabolism, impairs development of immune tolerance to autoantigens in NOD mice, a model for human autoimmune type 1 diabetes (T1D). Whether IDO1 function is also defective in T1D is still unknown. We investigated IDO1 function in sera and peripheral blood mononuclear cells (PBMCs) from children with T1D and matched controls.

Description of the EUROBIS program: a combination of an Epode community-based and a clinical care intervention to improve the lifestyles of children and adolescents with overweight or obesity.

The present paper describes the Epode Umbria Region Obesity Prevention Study (EUROBIS) and aims to implement the C.U.R.

Parental alliance and family functioning in pediatric obesity from both parents' perspectives.

Objective: The aim of the present study was to investigate the maternal and paternal specific contributions on the associations between family socioeconomic status, parental anthropometric factors, parental alliance, and family functioning. These were assessed separately for mothers and fathers, by means of a case-control study with families of Italian youths with and without overweight/obesity.

Methods: Ninety families with children aged 11 to 16 years (mean = 13.

Retrovirus-like long-terminal repeat DQ-LTR13 and genetic susceptibility to type 1 diabetes and autoimmune Addison's disease.

Controversial data are available on the association between the retrovirus-like long-terminal repeat (LTR) DQ-LTR13 and genetic susceptibility to type 1 diabetes and other autoimmune diseases. We analyzed DNA samples from 315 type 1 diabetic patients, 166 autoimmune Addison's disease (AAD) patients, 1,054 healthy subjects, and 144 families of type 1 diabetic offspring. DQ-LTR13 was more frequent among patients than healthy subjects (P(c) < 0.
