A team of researchers with the Department of Medicine at the University Erlangen-Nuernberg in Germany recently set out to examine the role of the innate immune system in celiac disease. The team included Maryam Rakhimova, Birgit Esslinger, Anja Schulze-Krebs, Eckhart G. Hahn, Detlef Schuppan and Walburga Dieterich.
The researchers matured dendritic cells taken from venous blood of patients with both active and with treated celiac disease, along with DQ2–DQ8-positive or negative control subjects. They treated the dendritic cells with a peptic–tryptic digest of gliadin (500 μg/ml)
and assessed activation by means of fluorescent-activated cell sorting analysis, cytokine secretion, and the cells' ability to trigger T cell proliferation.

However, gliadin-stimulated dendritic cells from patients with active celiac disease showed greater stimulation of autologous T cells compared to the other groups. The team concluded that further research should be aimed at identifying the mechanisms that control inflammation in healthy individuals.
