What this trial studies

This study involves up to 30 participants with celiac disease who have been on a gluten-free diet for at least six months. Participants will consume gluten-containing cookies or bread for three days, after which blood samples will be collected before and six days after the gluten challenge. The study aims to analyze gluten-specific T cells using HLA-tetramers and flow cytometry, providing insights into the immune response to gluten. Additional analyses will include other T cell populations to understand the broader immune response.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 80 with a confirmed diagnosis of celiac disease who have adhered to a gluten-free diet for the past six months.

Not a fit: Patients who are pregnant, breastfeeding, or have serious reactions to gluten may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of the immune mechanisms in celiac disease and lead to improved management strategies.

How similar studies have performed: Similar studies have explored immune responses in celiac disease, but this specific approach to analyzing gluten-specific T cells is relatively novel.
