To further explore the role of GC sensitivity in BD, we assessed transactivating and transrepressing capacity of GC in vitro by measuring the EC50 values of two representative GC-mediated genes, GILZ (TSC22D3) and IL2. We measured higher EC50 values of both genes in BD, indicating decreased in vitro GC sensitivity compared with healthy controls. The gene discussed is IL2; the disease is Behcet disease.
