Background: The microvasculature is a target organ for the early manifestations of cardiovascular disease. Therefore, a better understanding of the prostaglandin system and characterising the effects of mPGES-1 inhibition and concomitant reduction of PGE 2 in vascular beds are of interest.Experimental Approach: The effects of mPGES-1 inhibition on constriction and relaxation of resistance arteries (diameter: 100-400 μm) from patients with end stage kidney disease (ESKD) and controls (Non-ESKD) were studied using wire-myography in combination with immunological and mass-spectrometry based analyses.
