NAMPT and chorioamnionitis: H&E staining (Figures 1A,B) and IHC evaluation of NAMPT expression (Figures 1C,D,E) in placental membranes from women with chorioamnionitis (n = 5) revealed significant inflammatory changes with neutrophil infiltration and focal necrosis (representative images in Figures 1A,B) and >10 fold increases in NAMPT staining compared to women without chorioamnionitis (n = 5) (Figure 1F).
