Signaling from the nervous system through the β2-adrenergic receptor can help control the type of inflammation that characterizes inflammatory bowel disease (IBD), a new mouse study shows. These findings suggest that new therapies targeting the same pathway as the nervous system may help control inflammation in IBD. The study, “β2-adrenergic receptor–mediated negative regulation of group 2 innate lymphoid cell responses,” was published in the journal Science. Diseases that are characterized by inflammation, such as IBD, tend to exh
