In 1994 I was diagnosed with celiac disease, which led me to create Celiac.com in 1995. I created this site for a single purpose: To help as many people as possible with celiac disease get diagnosed so they can begin to live happy, healthy gluten-free lives. Celiac.com was the first site on the Internet dedicated solely to celiac disease, and since then it has become an invaluable resource to people worldwide who seek information about celiac disease and the gluten-free diet.
In 1998 I created The Gluten-Free Mall, Your Special Diet Superstore! which was also another Internet first—it was the first gluten-free food site to offer a shopping cart-style interface, and the ability for people to order gluten-free products manufactured by many different companies at a single Web site.
I am also co-author of the book Cereal Killers, and founder and publisher of Journal of Gluten Sensitivity.

Department of Clinical pathology, University of Vienna, Vienna, Austria. The in vitro challenge of duodenal mucosa with gliadin is a useful model to reproduce the immunological features of celiac disease (CD) and allows the study of early pathogenetic events in this disease. With this model it was shown that antigens such as ICAM-1 and HLA-DR are upregulated as early as 1-2 h after gliadin challenge in patients with CD. After 24 h the lamina propria contained CD4+ T cells expressing the IL-2 receptor alpha-chain, which is a sign of activation. intraepithelial lymphocytes increased in number and showed proliferative activity. After in vitro stimulation with gliadin, endomysial antibodies were found in the supernatant of the cultured mucosa from patients with celiac disease following a gluten-free diet. This supported the notion that endomysial antibodies are at least in part produced locally. The model was also successfully used to identify toxic constituents of gliadin. Presently, organ culture is not commonly used for diagnostic purposes.
