| Outline of Final Research Achievements |
I showed the novel phenotype of renal dendritic cell (RDC), CD11c+F4/80+PDCA1+. Furthermore, RDCs expressed PGE2 receptor as well as Cox-2 and mPGES-1 molecule involved in prostaglandin E2 synthesis which is known as an inflammatory mediator. These findings suggested that RDC function might be regulated by PGE2 autocrine manner.
In in vivo experiment, the population of RDCs in UUO (unilateral ureteral obstruction) mouse kidney were decreased, in which model is known that PGE2 expression is upregulated. However, the expressions of MHC classII molecule, IL-12/23p40 and IL-23p19 were significantly increased in RDCs migrated in UUO kidney.
