The new salicylate derivative UR-1505 modulates the Th2/humoral response in a dextran sodium sulphate model of colitis that resembles ulcerative colitis.
The aim of the present study was to evaluate the inmunomodulatory effects of UR-1505, a new salicylate derivative, on the T helper (Th)2/humoral response produced during dextran sodium sulfate (DSS)-induced rat colitis. In the in vitro studies, UR-1505 (300 microM) inhibited both the production of interleukin (IL)-10 and IL-5 in concanavalin A (Con A)-activated splenocytes and the production of immunoglobulin (Ig) G and IgA by B-lymphocytes. However, in contrast to the in vitro results, the administration of UR-1505 (10 and 30 mg/kg per day) to rats with established DSS-colitis enhanced both IL-10 and IgA production, whereas it inhibited IgG production, thus ameliorating the intestinal inflammation.
