Abstract

Parkinson's disease (PD) is associated with a loss of neurons from the midbrain. The cause of PD is unknown, but it is established that certain neurotoxins can cause similar syndromes. The brain is normally protected from these noxious blood-borne chemicals by the blood-brain barrier which includes specialized proteins on the inside of blood vessels in the brain. These act as molecular efflux pumps and P-glycoprotein (P-gp) is an abundant representative. Vulnerability to PD appears codetermined by the genotype for the P-gp gene. We hypothesized that PD patients have reduced P-gp function in the blood-brain barrier. We used positron emission tomography to measure brain uptake of [(11)C]-verapamil, which is normally extruded from the brain by P-gp. Here, we show significantly elevated uptake of [(11)C]-verapamil (18%) in the midbrain of PD patients relative to controls. This is the first evidence supporting a dysfunctional blood-brain barrier as a causative mechanism in PD.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • ABCB1 (P-gp) has reduced expression in vivo in PD patients.

    “Highly expressed at the BBB endothelium, MDR1 encodes for ABCB1 (P-gp) that has reduced expression in vivo in PD patients, and is proposed to contribute to PD progression (327).”

  • In Parkinson's disease patients, diminished activity of ABCB1 (P-gp) in mid-brain regions has been shown by [11C]verapamil PET.

    “Diminished activity of a major BBB active efflux transporter ABCB1 (P-gp) has been shown in the mid-brain regains of PD patients by accumulation of [ 11 C]verapamil using PET technique (327).”

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.
