SAN FRANCISCO (GenomeWeb) – Researchers at Seattle Children's Hospital have launched a clinical trial that aims to identify the immune pathways involved in inflammatory bowel disease and in patients who undergo bone marrow transplantation and develop graft versus host disease of the gastrointestinal tract.

The goal is to identify immune system-related gene expression signatures that can lead to better diagnosis of the diseases, enabling subtyping to identify the most severe cases, and even to enable targeted treatment.
