Adaptations in endocannabinoid signaling in response to repeated homotypic stress: a novel mechanism for stress habituation

Abstract

Daily life stressors are a major environmental factor contributing to precipitation and exacerbation of mental illness. Animal models using repeated homotypic stress induce anxious and depressive phenotypes and are used to study the pathophysiology of affective disorders. Here we discuss data demonstrating that repeated homotypic stress produces temporally and anatomically distinct changes in endocannabinoid signaling components within stress‐responsive brain regions. We also present evidence describing the neural and behavioral correlates of these adaptations in endocannabinoid signaling. These data support a role for endocannabinoid signaling in the central nervous system response to chronic, homotypic stress, and specifically in the process of stress–response habituation. The clinical implications of these findings for the pathophysiology and treatment of affective disorders are discussed.

  • Recent preclinical evidence indicates that stress mobilizes the eCB system in both the brain and the periphery, and that the eCB system can modulate behavioral and endocrine responses to both acute and chronic stress.

    “Recent preclinical evidence indicates that stress also mobilizes the endocannabinoid (eCB) system in both the brain and the periphery, and that the eCB system can modulate behavioral and endocrine responses to both acute and chronic stress (Hill et al, 2010;Patel and Hillard, 2008).”
  • Recent studies in animals and humans point to a major role of EC signaling in both the periphery and central nervous system in controlling adaptive processes to aversive situations and regulating and limiting stress reactions.

    “Despite the abovementioned diversity in central and peripheral functions, recent studies in animals [9] and humans [10] point to a major role of EC signaling in both the periphery [10] and central nervous system [11] in controlling adaptive processes to aversive situations and regulating and limiting stress reactions.”

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.
