Stressful early life experiences and immune dysregulation across the lifespan

Abstract

There is considerable evidence that stressful early life events influence a variety of physical health problems later in life. Childhood adversity has been linked to elevated rates of morbidity and mortality from a number of chronic diseases. Immune dysregulation may be one potential pathway that explains this link. In this mini-review, we summarize human studies demonstrating that severe early life stressors have lasting immune consequences. We propose a model outlining potential biobehavioral pathways that explain how early life stressors leave people vulnerable to these maladaptive outcomes. Finally, we suggest ideas for future work to test different aspects of this model.

  • ELA has been linked in human studies and animal experimentation to chronic inflammation and low-level immunosuppression, including impairment of mucosal immunity in children and cellular immunity in adolescents and adults.

    “ELA has been linked in human studies and animal experimentation to chronic inflammation [59] and low-level immunosuppression, including impairment of mucosal immunity in children [60] and cellular immunity (e.g., poorer control of latent viral infection) in adolescents [61] and adults [62].”

    From Biological embedding of childhood adversity: from physiological mechanisms to clinical implications (2017) · cites this paper as [59]

    Section 2.1 (Inflammation; page unavailable) reports elevated inflammation after early-life adversity in human studies, including an association persisting into adulthood. But the Introduction says the review focuses entirely on human studies, so it does not substantiate the sentence’s reference to animal experimentation. The immunosuppression examples carry separate citations and are not assessed as claims attributed to this source. (LLM, conf=0.86)

  • Early-life stress is a critical factor in lifelong immune dysregulation.

    “early-life stress has been identified as a critical factor in lifelong immune dysregulation.”
  • The elevated inflammatory markers in individuals with adverse childhood experiences suggest a sustained pro-inflammatory state.

    “Individuals with adverse childhood experiences often exhibit elevated inflammatory markers even decades later, suggesting a sustained pro-inflammatory state [48].”
  • Individuals with adverse childhood experiences often exhibit elevated inflammatory markers even decades later.

    “Individuals with adverse childhood experiences often exhibit elevated inflammatory markers even decades later, suggesting a sustained pro-inflammatory state [48].”
  • Early-life psychological stress-from abuse, neglect, maltreatment, bullying or low socioeconomic conditions-can intensify neural threat responses, increase inflammatory activity, change immune competence, and produce SCI across the lifespan.

    “exposure to psychological stress early in life—for example, in the form of abuse, neglect, maltreatment, bullying or living in a low socioeconomic environment—can heighten neural responses to threat that can upregulate inflammatory activity170, alter immuno-competence and lead to SCI throughout the lifecycle27,169”

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.
