Abstract

Chronic psychological stress has been shown to adversely impact immune system functions and compromise host defenses against various infections. However, the underlying mechanisms remain elusive. Recent studies have demonstrated that myeloid-derived suppressor cells (MDSCs) play an important role in regulating immunity. It is of interest to explore whether or not chronic psychological stress plays immunosuppressive functions partially by inducing MDSCs accumulation. In this work, we report that chronic psychological stress led to the accumulation of CD11b+Gr1+ cells in the bone marrow of BALB/c mice. Repeated β-agonist infusion showed no such effect. However, β-adrenergic blockade, but not glucocorticoids blockade, partially reversed the accumulation of CD11b+Gr1+ cells under the condition of chronic psychological stress, suggesting catecholamines collaborate with other factors to induce the accumulation. Further exploration indicates that cyclooxygenase 2 (COX-2)-prostaglandin E2 (PGE2) loop might act downstream to induce the accumulation. A majority of the accumulated CD11b+Gr1+ cells were Ly6G+Ly6C(low) immature neutrophils, which inhibited cytokine release of macrophages as well as T cell responsiveness. Moreover, the accumulated CD11b+Gr1+ cells under the condition of chronic psychological stress expressed multiple inhibitory molecules. Taken together, our data demonstrate for the first time that chronic psychological stress induces MDSCs accumulation in mice, which can contribute to immunosuppression.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Chronic restraint stress is associated with diminished NK cell function, cytokine secretion, and enhanced viral replication, and its opposing immune effects on myeloid cells compared with RSD can be accounted for by differences in circulating GCs.

    “For example, several studies investigated the immune response to chronic restraint stress and reported diminished natural killer (NK) cell function, cytokine secretion, and enhanced viral replication (Hunzeker et al, 2004;Tseng et al, 2005;Jin et al, 2013).”
  • ATP binds to P2X 7 and initiates K + efflux from the cell.

    “ATP binds to P2X 7 and initiates K + efflux from the cell.”
  • Stress-induced ATP can stimulate IL-1β release to influence behavior via the NLRP3 inflammasome.

    “Clear evidence that stress-induced ATP can stimulate IL-1β release to influence behavior and does so via the NLRP3 inflammasome.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
