mPGES1-Dependent Prostaglandin E (PGE) Controls Antigen-Specific Th17 and Th1 Responses by Regulating T Autocrine and Paracrine PGE Production.

The integration of inflammatory signals is paramount in controlling the intensity and duration of immune responses. Eicosanoids, particularly PGE, are critical molecules in the initiation and resolution of inflammation and in the transition from innate to acquired immune responses. Microsomal PGE synthase 1 (mPGES1) is an integral membrane enzyme whose regulated expression controls PGE levels and is highly expressed at sites of inflammation.
