Introduction-objective: Fas-mediated thyroid cell apoptosis is differentially regulated in autoimmune thyroid disease (AITD) being up-regulated in Hashimoto’s thyroiditis (HT) and down-regulated in Graves’ disease (GD). The soluble form of Fas (sFas), lacking the transmembrane domain due to alternative splicing may inhibit apoptosis by binding to Fas ligand. In this preliminary study we examined whether sFas is also differentially expressed in patients with AITD....
