Celiac disease (CD) is an intestinal disorder with multifactorial etiology. HLA and non-HLA genes together with gluten and possibly additional environmental factors are involved in disease development. Evidence suggests that CD4(+) T cells are central in controlling an immune response to gluten that causes the immunopathology, but the actual mechanisms responsible for the tissue damage are as y...

OBJECTIVE To investigate the prevalence of coeliac disease (CD) in an adult population with Turner's syndrome (TS). Design A clinic population with TS was screened using a serological test for CD. METHODS Two hundred and fifty six patients with TS were included in the study. Five patients had existing diagnoses of CD. The remaining 251 asymptomatic patients were screened using an IgA endomysi...

BACKGROUND & AIMS Celiac disease (CD) is a common chronic disorder of the small intestine, resulting from aberrant cellular responses to gluten peptides, and often remains undiagnosed. It is a complex genetic disorder, although 95% of the patients carry the risk heterodimer human leukocyte antigen (HLA)-DQ2. Genome-wide association studies on CD have identified 9 non-HLA loci that also contribu...

Celiac disease (CD) is an intestinal chronic disorder with multifactorial etiology resulting in small intestinal mucosal injuries and malabsorption. Trigger from gluten and related cereal proteins, HLA-DQ2/DQ8 molecules and autoantibodies to tissue transglutaminase, are essential to precipitate the disease. Genetic, dietary and immunological factors explain geographically regional differences i...

Celiac disease (CD) is an enteropathy triggered by the ingestion of gluten proteins from wheat and similar proteins from barley and rye. The inflammatory reaction is controlled by T cells that recognize gluten peptides in the context of human leukocyte antigen (HLA) DQ2 or HLA-DQ8 molecules. The only available treatment for the disease is a lifelong gluten-exclusion diet. We have used RNAi to d...

The immune system is initiated and regulated through a process starting from the binding of antigenic peptides to major histocompatibility complex (MHC) molecules. Detailed understanding of such interactions would lead to the development of vaccine design for infectious diseases, and immunotherapies for autoimmune diseases and cancer. Since MHC class II genes are highly polymorphic, a computati...

Celiac disease (CD) patients are intolerant to gluten, proteins in wheat, and related cereals. Virtually all patients are human leukocyte antigen (HLA)-DQ2 or HLA-DQ8 positive and several studies have demonstrated that CD4 T cells specific for (modified) gluten peptides bound to these HLA-DQ molecules are found in patients but not in control subjects. These T cell responses are therefore though...

The T-cell receptor (TCR) Valpha/beta gene product expression upon in vitro stimulation with mycobacteria was investigated to assess whether T-cell proliferation was associated with any specific TCR V gene usage. T-cell-enriched populations from peripheral blood of Mycobacterium bovis BCG-vaccinated healthy blood donors were stimulated in vitro with live or killed M. tuberculosis or with a solu...
