Schematic diagrams depicting the proposed relationship between 5-HT released from EC cells under healthy conditions and in colitis. In colitis, there is a reduction in SERT expression by enterocytes, which leads to more 5-HT entering the circulation and greater activation of 5-HT1B receptors in bone, which has a negative impact on bone mass.
