Presepsin is secreted by blood cells immunostained with CD163. (a) Immunofluorescence staining of presepsin and CD163. Presepsin (green) and CD163 (red) immunostaining can be observed in the same cells. Nuclei were counterstained with DAPI (blue). Scale bars, 50 μm. (b) The double-positive ratio of presepsin-CD163. We selected 6 cases of tubulointerstitial nephritis with severe interstitial inflammatory cell infiltration. The double-positive ratio of five fields for each case is presented (total, 30 fields). DAPI, 4’,6-diamidino-2-phenylindole.
