The placenta‐brain‐axis

Abstract

All mammalian species depend on the placenta, a transient organ, for exchange of gases, nutrients, and waste between the mother and conceptus. Besides serving as a conduit for such exchanges, the placenta produces hormones and other factors that influence maternal physiology and fetal development. To meet all of these adaptations, the placenta has evolved to become the most structurally diverse organ within all mammalian taxa. However, commonalities exist as to how placental responses promote survival against in utero threats and can alter the trajectory of fetal development, in particular the brain. Increasing evidence suggests that reactions of the placenta to various in utero stressors may lead to long‐standing health outcomes, otherwise considered developmental origin of health and disease effects. Besides transferring nutrients and gases, the placenta produces neurotransmitters, including serotonin, dopamine, norepinephrine/epinephrine, that may circulate and influence brain development. Neurobehavioral disorders, such as autism spectrum disorders, likely trace their origins back to placental disturbances. This intimate relationship between the placenta and brain has led to coinage of the term, the placenta‐brain‐axis. This axis will be the focus herein, including how conceptus sex might influence it, and technologies employed to parse out the effects of placental‐specific transcript expression changes on later neurobehavioral disorders. Ultimately, the placenta might provide a historical record of in utero threats the fetus confronted and a roadmap to understand how placenta responses to such encounters impacts the placental‐brain‐axis. Improved early diagnostic and preventative approaches may thereby be designed to mitigate such placental disruptions.

  • External neurotransmitter sources, such as the placenta, can play a role in the early shaping of cortical areas.

    “External neurotransmitter sources, such as the placenta, can play a role in this early shaping of cortical areas [114, 118, 241, 242].”

    From Development of prefrontal cortex (2022) · cites this paper as [241]

    The Placental Production of Neurotransmitters section says placental neurotransmitters can influence early fetal brain development; its Serotonin subsection describes effects on neuronal migration, differentiation, and synaptogenesis. Our copy does not specifically connect those effects to the early shaping of cortical areas. (LLM, conf=0.84)

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.
