A model of fibrocytes in the pathogenesis of thyroid-associated orbitopathy (TAO). Fibroblasts are uniformly CD34 in healthy humans and CD34+ in TAO patients. Fibrocytes appear to infiltrate the orbit in TAO and transition into CD34+ orbital fibroblasts, which express much higher levels of thyroglobulin (Tg) and thyroid-stimulating hormone receptor (TSHR), and mediate orbital inflammation and remodeling. Bovine thyroid-stimulating hormone (bTSH) and M22 are TSHR inhibitors.
