Abstract

Celiac disease (CD) is an autoimmune enteropathy characterized by intestinal malabsorption and immunological responses to dietary gliadins and an auto antigen located in the endomysium. The latter has recently been identified as the enzyme tissue transglutaminase (tTG). The linkage between gliadins, tTG and the autoimmune response has still to be clarified. In this work we report the production and analysis of a phage antibody library from the peripheral blood lymphocytes (PLB) of a CD patient. The library contained polyreactive and monoreactive antibodies to alpha-gliadin, to the dietary antigen beta-lactoglobulin, but not to tTG. The majority of the VH regions of the anti-alpha-gliadin antibodies belonged to the VH 4 family. The possibility of exploiting phage display antibodies as tools to study the molecular events associated with CD is discussed.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
