Changes in monocyte cell surface expression of β2-integrins (CD11a, CD11b and CD11c) as a function of stress reactivity, indexed by change in negative affect (Quartiles 1,2,3 and 4) following exposure to the Anger Recall Interview (ARI). Data represent the adjusted change in Mean Fluorescent Intensity (+SD) of monocytic β2-integrins, controlling for age, sex, body mass index (BMI), exercise status and baseline level. Monocyte cell surface expression of β2-integrins was significantly greater in the upper quartile range of negative affect (Q4). A similar pattern of findings was observed for norepinephrine (Ne) and diastolic blood pressure (DBP) reactivity (data not shown). *p < .05 relative to quartiles 1 and 3 for CD11a and CD11b, and quartiles 1, 2 and 3 for CD11c.
