Abstract

Brain endothelial cells are unique among endothelial cells in that they express apical junctional complexes, including tight junctions, which quite resemble epithelial tight junctions both structurally and functionally. They form the blood-brain-barrier (BBB) which strictly controls the exchanges between the blood and the brain compartments by limiting passive diffusion of blood-borne solutes while actively transporting nutrients to the brain. Accumulating experimental and clinical evidence indicate that BBB dysfunctions are associated with a number of serious CNS diseases with important social impacts, such as multiple sclerosis, stroke, brain tumors, epilepsy or Alzheimer's disease. This review will focus on the implication of brain endothelial tight junctions in BBB architecture and physiology, will discuss the consequences of BBB dysfunction in these CNS diseases and will present some therapeutic strategies for drug delivery to the brain across the BBB.

  • Blood-brain barrier integrity can be compromised by exposures to certain toxicants and by health conditions through molecular alterations in barrier function.

    “Integrity of the BBB can be compromised because of exposures to certain toxicants, such as pesticides, mixed vehicle emissions, and tobacco smoke, as well as certain health conditions including diabetes and neurological disorders reviewed in Neurotoxicity of PFAS in Sensitive Populations, through molecular alterations in barrier function (Gupta et al., 1999; Weiss et al., 2009; Mazzone et al., 201”

    From A Critical Review and Meta-Analysis of Impacts of Per- and Polyfluorinated Substances on the Brain and Behavior (2022) · cites this paper as Weiss et al., 2009

    Section 3 describes BBB dysfunction in neurological diseases, and §3.2.1 explains molecular changes that damage barrier integrity after stroke (page numbers unavailable). The cited passages do not substantiate the sentence’s specific claims about pesticides, vehicle emissions, tobacco smoke, or diabetes. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • PFAS exposure could be more hazardous for individuals with pre-existing neurological conditions or a predisposition for these diseases.

    “PFAS exposure could be more hazardous for individuals with pre-existing neurological conditions or a predisposition for these diseases”

    From A Critical Review and Meta-Analysis of Impacts of Per- and Polyfluorinated Substances on the Brain and Behavior (2022) · cites this paper as Weiss et al., 2009

    Sections 3.1 and 3.5.1 describe blood–brain barrier dysfunction in multiple sclerosis and Alzheimer’s disease, including increased permeability, and section 3.1 discusses genetically predisposed individuals. The paper does not address PFAS exposure or establish that it is more hazardous for people with these conditions or predispositions. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Many neurological conditions confer heightened damage by PFAS and other toxicants by functionally compromising the BBB.

    “Many neurological conditions, including Alzheimer’s disease (AD), Parkinson’s Disease (PD), multiple sclerosis (MS), Amyotrophic lateral sclerosis (ALS), Huntington’s disease, and brain tumors, confer heightened damage by PFAS and other toxicants by functionally compromising the BBB”

    From A Critical Review and Meta-Analysis of Impacts of Per- and Polyfluorinated Substances on the Brain and Behavior (2022) · cites this paper as Weiss et al., 2009

    Sections 3.1, 3.3.1, and 3.5 describe BBB dysfunction in MS, brain tumors, AD, and PD; the Conclusion says the BBB protects the CNS from xenobiotics. But the paper does not establish that these conditions heighten damage from PFAS or other toxicants, and the retrieved passages do not substantiate BBB compromise in ALS or Huntington’s disease. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Asiaticoside and madecassoside cross the blood-brain barrier at a high rate, with asiaticoside showing the highest permeability, followed by madecassoside, and with higher permeability coefficient values than donepezil.

    “The experiment demonstrated the remarkably high capability of the tested phytocompounds in crossing the BBB, with asiaticoside showing the highest permeability, followed by madecassoside. Notably, the compounds also showed higher permeability coefficient values than donepezil, a drug commonly used for AD. 43”

    From Therapeutic Properties and Pharmacological Activities of Asiaticoside and Madecassoside: A Review (2023) · cites this paper as [43]

    Section 2.3.1 discusses general factors affecting BBB solute permeability, but does not report permeability results for asiaticoside or madecassoside. Searches of our copy for those compounds and donepezil found no passage comparing their permeability coefficients or ranking their BBB crossing rates; page numbers were not available. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Asiaticoside and madecassoside cross the blood-brain barrier at a high rate without exerting toxic effects and while preserving the blood-brain barrier tight junction integrity.

    “In the same study using primary porcine brain endothelial cells, asiaticoside and madecassoside were proved to be efficient in crossing the BBB at a high rate without exerting any toxic effects, and while preserving the BBB tight junction integrity, making them desirable neurotherapeutics.”

    From Therapeutic Properties and Pharmacological Activities of Asiaticoside and Madecassoside: A Review (2023) · cites this paper as [43]

    The review’s sections 2.2 (Intercellular junctions) and 4 (Therapeutic approaches) discuss BBB integrity and drug delivery generally, but neither reports the claimed findings for asiaticoside or madecassoside. Searches of our full-text copy for both compounds and for the primary porcine brain endothelial-cell study found no passage addressing their crossing rate, toxicity, or effects on tight junctions. Page numbers were not available in our copy. (LLM, conf=0.77)

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.
