Modulation of Inflammatory Reactions by Low-Dose Ionizing Radiation: Cytokine Release of Murine Endothelial Cells Is Dependent on Culture Conditions

Figure 4

Adhesion of WEH.1 monocytes to irradiated EC (a) nonactivated and (b) activated with TNF-α prior to IR. The percentage adhesion of monocytes to EC was determined by flow cytometric analysis 24 hours after irradiation with low doses of X-rays and normalized to the sham-irradiated, nonactivated samples. Changes in monocyte binding are presented as deviation (SD) from four independent experiments performed in duplicates; asterisks illustrate significance: and .
(a) Without TNF-α
(b) With TNF-α
