Abstract

OBJECTIVE: Anticipatory cognitive appraisal can affect the stress-induced release of stress hormones and stress hormones can modulate monocyte cytokine expression. We investigated whether anticipatory cognitive appraisal processes would predict changes in monocyte cytokine expression following psychosocial stress in relation to stress hormone release. METHODS: Forty-four men (mean age 43+/-2 years; mean arterial blood pressure (MAP) 102+/-2 mmHg; mean body mass index (BMI) 26+/-.4kg/m(2)) completed the Primary Appraisal Secondary Appraisal (PASA) scale before undergoing the Trier Social Stress Test (combination of mock job interview and mental arithmetic task). Lipopolysaccharide (LPS)-stimulated tumor necrosis factor (TNF)-alpha and interleukin (IL)-6 expression by monocytes was assessed in vitro immediately before and after stress, and during recovery up to 60min post-stress. Moreover, we repeatedly measured salivary cortisol as well as plasma epinephrine and norepinephrine levels. RESULTS: Stress hormones increased and cytokines decreased following stress (all p<0.05). Correlation analyses showed that a higher PASA "stress index" was associated with higher expression (area under the curve, AUC) of total LPS-stimulated TNF-alpha (r=.33, p=.03) and IL-6 (r=.32, p=.33) between rest and 60min post-stress. While controlling for age, BMI, and MAP, higher values in the primary PASA scale "control expectancy" predicted lower TNF-alpha expression following stress (ss=-.42, p=0.003). Higher "control expectancy" (ss=-.32, p=0.031) and lower "challenge" (ss=.30, p=0.046) predicted lower IL-6 expression. None of the stress hormones predicted expression of any cytokine. CONCLUSIONS: We found that anticipatory cognitive stress appraisal modulates monocyte inflammatory activity following stress suggesting that interventions aiming at improving coping skills might modify the monocyte cytokine response.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
