Cutting edge: differential production of prostaglandin D2 by human helper T cell subsets.

Several effector molecules, including cytokines, are differentially produced by Th1 and Th2 cells. We used a gene expression screen method to identify a gene encoding hematopoietic PG D synthase ( hPGDS) which was preferentially expressed in human Th2 but not Th1 clones. Studies with anti- hPGDS mAbs confirmed the Th2-dominated expression of hPGDS protein. Upon stimulation with anti-CD3 plus anti-CD28 mAbs, coordinated cyclooxygenase-2 expression and PGD2 production were induced in Th2 lines. hPGDS expression was also observed in a small population (<1.0%) of peripheral blood CD4+ lymphocytes from healthy adults. Most hPGDS-expressing CD4+ lymphocytes showed a typical Th2-type cytokine pattern. Our results suggest that, at the sites of Ag presentation, at least part of the Th2 cell population produces PGD2, which may be involved in various aspects of Th2-related immune responses similar to mast cells.[1]
