Expansion of the orbital contents, by adipogenesis and hyaluronan (HA) overproduction, causes Graves orbitopathy (GO). Orbital HA is generated predominantly by hyaluronan synthase 2 (HAS2) whose transcription is positively regulated by pAkt in cell lines. GO is most frequently associated with Graves’ disease (GD) in which thyroid stimulating antibodies bind the TSH receptor (TSHR) increasing cAMP. Previous studies highlight a role for TSAB and ‘neutral’ TSHR ant...
