Abstract

Of Mice and Men: Just how closely must mouse models replicate the known features of human disorders to be accepted as useful for mechanistic and therapeutic studies? Soliman et al. (p. 863 , published online 14 January) compared mice that vary only in their allelic composition at one position within the gene encoding brain-derived neurotrophic factor (BDNF) with humans exhibiting the same range of allelic variation. Individuals (mice and humans) carrying the allele that codes for a methionine-containing variant of BDNF retained a fearful response to a threatening stimulus even after its removal in comparison to those with the valine variant. Furthermore, in both cases, this linkage was mediated by diminished activity in the ventral-medial region of the prefrontal cortex. This deficit in extinction learning may contribute to differential responses to extinction-based therapies for anxiety disorders.

  • Both rodents and humans with BDNF Val66Met polymorphisms exhibit impaired fear extinction learning and reduced mPFC activity during extinction.

    “Both rodents and humans with BDNF Val66Met polymorphisms exhibit impaired fear extinction learning and reduced mPFC activity during extinction (138)”

    From Psychedelics and Other Psychoplastogens for Treating Mental Illness. (2021) · cites this paper as [138]

    The paper reports impaired fear extinction in both mice and humans carrying the Met allele, and significantly reduced vmPFC activity during extinction in human carriers (section labeled Abstract; page unavailable). For mice, it reports only a trend toward blunted vmPFC c-Fos expression after extinction, not an established reduction in mPFC activity during extinction. (LLM, conf=0.90)

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.
