Abstract

Availability of nicotinic acetylcholine receptors containing beta2 subunits (beta2-nAChRs) was studied in unmedicated, symptomatic patients with post-traumatic stress disorder (PTSD) and healthy control subjects, all current non-smokers. A subgroup of participants had a history of smoking. Availability of beta2-nAChRs in the mesiotemporal cortex, prefrontal cortex, thalamus and striatum was determined using the radiotracer [123I]5-IA-85380 ([123I]5-IA) and single-photon emission computed tomography (SPECT). PTSD symptoms were assessed using the Clinician-Administered PTSD Scale (CAPS). Never-smoking PTSD patients compared to never-smoking healthy controls showed significantly higher [123I]5-IA binding in the mesiotemporal cortex (ANOVA: F=6.21, d.f.=1, 11, p=0.030). Among all PTSD patients, there was a significant correlation between the re-experiencing symptom cluster and thalamic [123I]5-IA binding (R2=0.66, p=0.019, Bonferroni corrected). These findings not only suggest an involvement of beta2-nAChRs in the pathophysiology of PTSD but also raise the possibility that this receptor may be a novel molecular target for drug development.

  • PTSD patients who never smoked showed significantly higher β2 nAChR density in the mesiotemporal cortex including the amygdala and hippocampus compared to healthy individuals who never smoked.

    “Czermak et al. (2008) found that PTSD patients who never smoked showed significantly higher β2 nAChR density in the mesiotemporal cortex including the amygdala and hippocampus compared to healthy individuals who never smoked.”

  • The effects of nicotine on hippocampus-dependent fear memories require activation and upregulation of high-affinity β2-containing nAChRs.

    “results from the studies using acute, chronic, and withdrawal from chronic nicotine suggest that the effects of nicotine on hippocampus-dependent fear memories require the activation and upregulation of the high-affinity β2-containing nAChRs.”

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.
