TNF and colitis: In the mouse colitis model, oral administration of BBR/CUR@MC inhibited ADAM17 in the TNF signaling pathway and MAPK11/13, COL4A1, and COL1A1 in the AGE-RAGE signaling pathway, thereby downregulating pro-inflammatory cytokines such as TNF-α and IL-1α, upregulating IL-10, scavenging ROS, significantly alleviating colonic inflammation and repairing the intestinal barrier in mice, with a therapeutic effect superior to that of single-drug microcapsules and 5-ASA.
