Abstract

In the cerebrum of patients with tuberous sclerosis (TSC), there are three types of nodular lesions: cortical tubers, subcortical heterotopic nodules and subependymal giant cell astrocytomas. Histologically, these hamartias and hamartomas contain abnormal giant cells that show evidence of abnormal differentiation of immature neural cells. Recent identification of the TSC1 and TSC2 genes has facilitated studies of the molecular pathology of TSC. The expression of their protein products, hamartin and tuberin, is altered in various TSC lesions. However, the molecular mechanism by which cortical tubers develop remains to be elucidated. The Eker rat, a naturally occurring animal model of TSC, will provide a powerful tool for future investigations of TSC.

  • Malformations of cortical development, known as cortical tubers, are a hallmark of TSC.

    “Malformations of cortical development, known as cortical tubers, are a hallmark of TSC5.”
  • Human TSC neuropathology shows abnormal migration and differentiation of neurons within and proximal to tubers in the cerebral cortex and abnormally large cells with features of neurons or astrocytes or both, indicating a defect in differentiation.

    “Neuropathologic observations in human subjects with TSC indicate abnormal migration and differentiation of neurons within and proximal to the tubers in the cerebral cortex [163] and the presence of abnormally large cells, which show features of either neurons or astrocytes or both, indicating a defect in differentiation [243].”

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.
