Mayo Clinic researchers have identified an immune-regulating molecule that may help explain why some patients with inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, do not respond to commonly used therapies. The findings, published in Cell Reports, describe a previously uncharacterized role for the molecule ST8Sia6 in regulating immune activity in the gut.
