Immune cell subset is associated with development of gastrointestinal GVHD after HSCT

Gastrointestinal graft vs. host disease (GI-GVHD) is a life threatening complication that can occur after allogeneic hematopoietic cell transplantation, a procedure that is commonly used to treat patients with leukemia. There is currently no way to predict which patients will develop GI-GVHD before the presentation of clinical symptoms. Unfortunately, the symptoms of GI-GVHD are not very specific and many patients undergo treatment for GI-GVHD in the absence of a confirmed diagnosis because the disease is so dangerous.

In this issue of JCI Insight, researchers led by Sophie Paczesny of Indiana University School of Medicine report the identification of a subset of that express the protein CD146 and are increased in that went on to develop GI-GVHD prior to the onset of clinical symptoms.

Paczesny and colleagues demonstrated that mice lacking CD146-expressing T cells had improved survival following allogeneic hematopoietic cell transplantation.

These findings indicate that the CD146-expressing cell subset could potentially be used as a marker to identify patients who are likely to develop GI-GVHD after .
