Teprotumumab is an IGF-1 receptor (IGF-1R) blocking human monoclonal antibody. Teprotumumab binds to the ligand binding extracellular α-subunit domain of Akt phosphorylation. Teprotumumab can be used for troid-associated ophthalmopat research[1].
Teprotumumab (0-500 μg/mL, 12 h) attenuates the actions of both IGF-1 and TSH in fibrocytes. IGF-1R and TSHR mRNA abundance is unaffected by Teprotumumab after 24 hours[1].
