Researchers are continuing to uncover what may happen in the gut before disease develops.
New research from the University of Toronto is challenging the traditional focus on inflammation by identifying a potential immune defect involving , a gene strongly associated with Crohn’s risk.
The researchers found that when NOD2 was not functioning properly, fewer T cells were recruited to the gut’s lymph nodes and those cells were less effective at responding to infection. They propose that this impaired immune response, combined with a more permeable intestinal barrier, could contribute to the earliest stages of Crohn’s disease.
It’s another piece of evidence pointing to the importance of understanding what happens before chronic inflammation takes hold. It may also help explain why treatments that target inflammation work well for some patients but not others.

Crohn’s disease, a condition characterized by widespread inflammation in the gut, may arise from a weakened immune response, according to new research from the University of Toronto’s Temerty Faculty of Medicine.For the study, researchers led by Dana Philpott, a professor of immunology and labor...
