Abstract

The blood‐brain barrier (BBB) is important physiologically. Pathologically, BBB disruption has been implicated in a wide spectrum of neurological disorders including Parkinson’s disease (PD). Recent studies indicate that caffeine is protective against PD, but by poorly understood mechanisms. Using a MPTP neurotoxin model of PD we tested the hypothesis that the protective actions of caffeine were because of, at least in part, preventing MPTP‐induced BBB dysfunction. FVB mice were pre‐treated with caffeine (10 mg/kg, i.p.) or saline for 7 days prior to initiation of neurotoxin treatments; during the 7 days of neurotoxin treatment, caffeine or saline continued to be administered 10 min before each dose of MPTP (20 mg/kg, i.p.). Striatum (and for some studies hippocampus and cerebral cortex as well) were evaluated for BBB leakage, tight junction protein expression levels, integrity of dopaminergic neurons, and activation of astrocytes and microglia using immunostaining, immunoblotting and real‐time PCR techniques. We found that caffeine blocked MPTP‐induced decreases in numbers of tyrosine hydroxylase‐positive dopaminergic neurons, increases in leakage of Evan’s blue dye and FITC‐albumin in striatum but not in cerebral cortex or hippocampus, decreases in levels of the tight junction proteins occludin and ZO‐1, and increases in reactive gliosis. Our results suggest that caffeine might protect against PD and PD‐like features in animal models, in part, by stabilizing the BBB.

  • Reduced expression of tight junction proteins has been shown in MPTP Parkinson's disease models.

    “Reduced expression of TJ proteins has also been shown in MPTP PD models (108).”

  • In rodent models of Parkinson's disease induced by MPTP or 6-OHDA, compromised blood-brain barrier integrity is observed, including leakage of FITC-albumin, horseradish peroxidase, and Evan's blue in the substantia nigra and striatum.

    “compromised BBB integrity is also observed in rodent models of PD induced by systemic administration of MPTP (108, 680) or intrastriatal administration of 6-hydroxydopamine (6-OHDA) (95), including leakage of fluoresceinisothiocyanate (FITC)-labeled albumin (95, 108, 680), horseradish peroxidase (95), and Evan's blue (108) in the substantia nigra and striatum.”

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.
