Regulation of endocannabinoid signaling by stress: Implications for stress-related affective disorders

Gorzalka, Boris B., Hill, Matthew N., Hillard, Cecilia J.·2008·Neuroscience & Biobehavioral Reviews

Abstract

The endocannabinoid system is a widely distributed, neuromodulatory system which serves an integral role in regulating synaptic transmission. The presence of this system in stress-responsive neural circuits suggests that it may play a critical role in regulating neuroendocrine and behavioral responses to stress. Endocannabinoid content in limbic structures which regulate activation of the hypothalamic-pituitary-adrenal (HPA) axis is dynamically regulated by stress. Under conditions of acute stress, the endocannabinoid system tonically constrains activation of the HPA axis. During repeated exposure to aversive stimuli, the endocannabinoid system up-regulates in limbic structures, resulting in dampened neural activity in stress circuits, which could contribute to stress habituation. Disrupted endocannabinoid signaling, on the other hand, is associated with an inability to adapt to chronic stress. Therapeutically, these data suggest that the endocannabinoid system could be dysregulated in affective disorders, such as depression, which are characterized by maladaptive stress coping. In this review, we discuss the evidence demonstrating that the endocannabinoid system is affected by and can oppose the effects of prolonged stress and, as such, represents a potential target for the development of novel antidepressant agents.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • The finding that acute psychosocial stress increases serum NAEs is consistent with other preclinical evidence that the eCB system is involved in the response to acute stress.

    “This finding is consistent with other preclinical evidence that the eCB system is involved in the response to acute stress (Gorzalka et al, 2008).”
  • Tonic ECB signaling in the BLA and elsewhere is mediated by AEA, whereas phasic ECB responses to robust neuronal activation are sub-served by 2-AG.

    “There is growing evidence that tonic ECB signaling in the BLA and elsewhere is mediated by AEA, whereas phasic ECB responses to robust neuronal activation are sub-served by 2-AG [53–56].”
  • Activating CB1 receptors or increasing AEA signaling prevents some effects of stress in the amygdala and hippocampus and can reduce stress-induced HPA axis activation.

    “Several studies have shown that activating CB1 receptors or increasing N-arachidonylethanolamine (AEA) signaling prevents some of the effects of stress in the amygdala and hippocampus and can reduce stress-induced HPA axis activation (Ganon-Elazar and Akirav, 2009;Patel et al, 2004;Gorzalka et al, 2008).”

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.
