From: Phenotypic characteristics of human monocytes undergoing transendothelial migration
Cytokine-pretreated endothelium increases CD54 expression on monocytes. The fluorescein isothiocyanate (FITC) mean fluorescence intensity (mfi) of monocytes that migrated through endothelium pretreated with tumour necrosis factor-α (TNF-α) (a) or interleukin-1α (IL-1α) (b) is compared with the mfi of monocytes that simultaneously migrated through untreated endothelium (control). Statistical significance: (a) P = 0.043; (b) P = 0.019.
