Research Abstract

First, I showed that in the point of view of decrease of IL-12p70 production, upregulation of IL-23 production, and enhanced expression of DC maturation markers, new DC subset which I previously identified had very similar characteristics to DC differentiated under prostaglandin E2 (PGE2).Next, I focused on interaction of PGE2 on DC. I showed that PGE2 interacted with renal-DC which had been considered to have important role for glomerulonephritis, and enhanced productions of pro-inflammatory cytokines for example IL-6.The present study suggested that the DC-PGE2 interaction would be involved in pathogenic and progression mechanism of glomerulonephritis.
