Abstract

Screening of cDNA libraries prepared from the frontal cortex of an Alzheimer disease patient and from fetal human brain has led to isolation of the cDNA for a core protein of the paired helical filament of Alzheimer disease. The partial amino acid sequence of this core protein was used to design synthetic oligonucleotide probes. The cDNA encodes a protein of 352 amino acids that contains a characteristic amino acid repeat in its carboxyl-terminal half. This protein is highly homologous to the sequence of the mouse microtubule-associated protein tau and thus constitutes the human equivalent of mouse tau. RNA blot analysis indicates the presence of two major transcripts, 6 and 2 kilobases lon g, with a wide distribution in normal human brain. Tau protein mRNAs were found in normal amounts in the frontal cortex from patients with Alzheimer disease. The proof that at least part of tau protein forms a component of the paired helical filament core opens the way to understanding the mode of formation of paired helical filaments and thus, ultimately, the pathogenesis of Alzheimer disease.

  • There are six tau isoforms expressed in the mature human brain.

    “There are six tau isoforms expressed in the mature human brain”

    From Tau hyperphosphorylation impairs cooperative binding to microtubules and perturbs organelle trafficking in neurons (2026) · cites this paper as Goedert et al., 1988

    The Discussion (page not provided) reports one sequenced form of human tau and describes cDNA evidence for a second form, suggesting that human tau mRNA may be alternatively spliced. It does not establish six isoforms or specify their expression in the mature human brain; its 6-kb measurement refers to transcript length, not isoform count. (LLM, conf=0.85)

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.
