Selective Cyclooxygenase-2 Inhibitor Suppresses Renal Thromboxane Production but Not Proliferative Lesions in the MRL/lpr Murine Model of Lupus Nephritis

These data demonstrate that renal TXA2 production is COX2 dependent in murine LN and suggest that NO production is directly or indirectly COX2 dependent. However, COX2 inhibitor therapy in this model failed to improve renal pathology, making COX2 inhibition a less attractive approach for treating LN.
