CD4＋FoxP3＋ regulatory T cells （Tregs） are immunosuppressive cells that are critical for immune tolerance. Several studies have demonstrated that one of the anti-inflammatory mechanisms of action of intravenous immunoglobulin （Wig） involves the expansion of Tregs. Recently, we demonstrated that IVIgmediated Treg expansion involves the cyclooxygenase-2 （COX-2）-dependent induction of prostaglandin E2 （PGE2） in human dendritic cells （DCs）. However, the validity of these findings in autoimmune patients is lacking.
