WebThe proportion of antibodies secreted against TSHR is directly proportional to the complications in GO patients. TRAb is involved in active GO more than inactive GO. Studies show patients with thyroidal TSHR and extrathyroidal TSHR have some analogous affects20. PDGF-AB and PDGF-BB increase the response produced by orbital fibroblast … WebDetection of TRAb in clinical rou-tine is performed by 2nd gen assays using human or porcine TSHR. Such TSH bin- ding inhibition immunoglobulin (TBII) assays determine the ability of TRAb to inhi- bit the binding of labelled TSH to immobilized TSHR. TRAb are present in low con- centrations and mostly recognize conformational epitopes.
