Celiac.com 06/24/2010 - Scientists have previously seen a nuclear fluorescence reactivity (NFR) pattern on monkey esophagus in sections which were exposed to celiac disease patients that were sera positive for anti-endomysium antibodies (EMA). Because of this prior knowledge, scientists created a new study to illustrate the NFR, to study  NFR positive results in connection with gluten withdrawal, and also to assess  the possible role of NFR in celiac disease follow-up's.

For twelve months, scientists closely evaluated twenty untreated celiac patients, eighty-seven treated celiac patients, and fifteen healthy control subjects. Scientists incubated the sera of all 122 patients on monkey esophagus sections. The goal was to evaluate the existence of NFR by indirect immunofluorescence analysis.

To asses the rate of NFR in culture supernatants, duodenal mucosa samples from treated celiac patients were challenged with gliadin
