Abstract

The age-associated decline of the neurological and cognitive functions becomes more and more serious challenge for the developed countries with the increasing number of aged populations. The morphological and biochemical changes in the aging brain are the subjects of many extended research projects worldwide for a long time. However, the crucial role of the blood-brain barrier (BBB) impairment and disruption in the pathological processes in age-associated neurodegenerative disorders received special attention just for a few years. This article gives an overview on the major elements of the blood-brain barrier and its supporting mechanisms and also on their alterations during development, physiological aging process and age-associated neurodegenerative disorders (Alzheimer's disease, multiple sclerosis, Parkinson's disease, pharmacoresistant epilepsy). Besides the morphological alterations of the cellular elements (endothelial cells, astrocytes, pericytes, microglia, neuronal elements) of the BBB and neurovascular unit, the changes of the barrier at molecular level (tight junction proteins, adheres junction proteins, membrane transporters, basal lamina, extracellular matrix) are also summarized. The recognition of new players and initiators of the process of neurodegeneration at the level of the BBB may offer new avenues for novel therapeutic approaches for the treatment of numerous chronic neurodegenerative disorders currently without effective medication.

Claims other papers make about this one

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

  • Normal physiological aging is associated with BBB disruption through multiple mechanisms including decreased expression of endothelial tight junction proteins, increased microglial activation, and neuronal senescence.

    “Normal physiological aging is associated with BBB disruption through multiple mechanisms including decreased expression of endothelial tight junction proteins, increased microglial activation, and neuronal senescence (Erdő et al., 2017).”
  • 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”

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.
