Abstract

This study was undertaken to determine if apolipoprotein (apo) E-containing lipoproteins and their receptors could provide a system for lipid transport and cholesterol homeostasis in the brain, as they do in other tissues. To accomplish this goal, the lipoproteins in human and canine cerebrospinal fluid (CSF) were characterized, and rat brain and monkey brain were examined for the presence of apoB,E(LDL) receptors. Apolipoprotein E and apoA-I were present in human and canine CSF, but apoB could not be detected. Apo-lipoprotein E and apoA-I were both present on lipoproteins with a density of approximately 1.09 to 1.15 g/ml. In human CSF, the lipoproteins were primarily spherical (approximately 140 A), whereas in canine CSF the lipoproteins were a mixture of discs (200 x 65 A) and spheres (approximately 130 A). Apolipoproteins E and A-I were contained primarily in separate populations of lipoproteins. Although the apoE of CSF was more highly sialylated than plasma apoE, the apoE-containing lipoproteins in canine CSF competed as effectively as canine plasma apoE HDLc for binding of 125I-LDL to the apoB,E(LDL) receptors on human fibroblasts. The presence of apoB,E(LDL) receptors in both rat and monkey brain was demonstrated by immunocytochemistry. Astrocytes abutting on the arachnoid space and pial cells of the arachnoid itself, both of which contact CSF, expressed apoB,E(LDL) receptors. Relatively few receptors were present in the cells of the gray matter of the cortex. Receptor…

  • ApoE plays a central role in brain lipid homeostasis by mediating endocytosis of HDL-like lipoprotein particles.

    “ApoE plays a central role in brain lipid homeostasis by mediating the endocytosis of HDL-like lipoprotein particles (30).”
  • Non-neuronal cells, mainly astrocytes and to some extent microglia, are the major cell types that express apoE in the brain.

    “Non-neuronal cells, mainly astrocytes and to some extent microglia, are the major cell types that express apoE in the brain (Grehan et al., 2001; Pitas et al., 1987).”

  • The predominant apolipoprotein of HDL in the central nervous system is apoE.

    “Unlike plasma HDL that contains apoA-1 as its major apolipoprotein, the predominant apolipoprotein of HDL in the central nervous system (CNS) is apoE (Pitas et al., 1987).”

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.
