title: Celiac disease: progress towards diagnosis and definition of pathogenic mechanisms.
abstract: The current issue of the International Reviews of Immunology is dedicated entirely to Celiac Disease (CD). Recent development of additional biomarkers and diagnostics resulted in a sharp revision of the prevalence of this condition, with a previously unrecognized subclinical occurrence in the adult population. This was paralleled by groundbreaking progress in understanding its molecular pathogenesis: while gluten-derived peptides activate the innate immunity, post-translationally modified gluten elicits an adaptive immunity. These arms amplify each other, resulting in a self- perpetuating autoimmune condition, influenced by disturbances of the gut flora and mucus chemistry. The process evolves dramatically in a subset of patients with vulnerable immune homeostasis (eg. Treg cells) explaining the progressive, aggravating syndrome in the clinically overt version of CD. In depth understanding of the pathogenesis of CD thus creates the premises of developing novel, more accurate animal models that should support a rationale development of new prophylactic and therapeutic interventions.
