Teprotumumab

Teprotumumab is an IGF-1 receptor (IGF-1R) blocking human monoclonal antibody. Teprotumumab binds to the ligand binding extracellular α-subunit domain of IGF-1R. Teprotumumab inhibits TSH and IGF-1 action in fibrocytes. Teprotumumab attenuates TSH-dependent IL-6 and IL-8 expression and Akt phosphorylation. Teprotumumab can be used for thyroid-associated ophthalmopathy 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].
