Conquering a severe complication of celiac disease

Summary:
One severe complication of celiac disease is enteropathy-associated T cell lymphoma, an invasive lymphoma with poor prognosis. New research has identified the anti-death signals transmitted to immune cells in the wall of the small intestine by the soluble factor IL-15 that contribute to the development of enteropathy-associated T cell lymphoma, providing potential new targets for treating type II refractory celiac disease -- an intermediary clinical state between celiac disease and enteropathy-associated T cell lymphoma.

One severe complication of celiac disease is enteropathy-associated T cell lymphoma, a high-grade invasive lymphoma with a very poor prognosis. Previous research has suggested that chronic exposure of immune cells in the walls of the small intestine, which are known as intraepithelial lymphocytes, to potent anti-death signals initiated by the soluble factor IL-15 contributes to the development of enteropathy-associated T cell lymphoma.

A team of researchers, at INSERM U989, Universitι Renι Descartes, France, has now identified the survival signals delivered by IL-15 to freshly isolated human intraepithelial lymphocytes and to intraepithelial lymphocyte cell lines derived from patients with type II refractory celiac disease -- a clinical state considered an intermediary step between celiac disease and enteropathy-associated T cell lymphoma. Importantly, treatment with an antibody directed at IL-15 caused intraepithelial lymphocytes to die and wiped out their accumulation in mice overexpressing human IL-15 in the lining of their gut.

The team, led by Nadine Cerf-Bensussan and Bertrand Meresse, therefore suggests that IL-15 and its downstream survival signals might provide new targets for the treatment of type II refractory celiac disease.

The research appears in the Journal of Clinical Investigation.
