Researchers from the Medical School of Nanjing University hypothesized that in ulcerative colitis, the gut-resident macrophages may be compromised, leading to impaired integrity of the epithelial barrier. “From a basic science standpoint, our work uncovers a novel etiology of ulcerative colitis. From a translational perspective, it identifies a promising therapeutic target, potentially paving the way for developing effective drugs to treat or even cure the disease,” senior author Minsheng Zhu told BioWorld.
