Abstract

BACKGROUND: We planned to analyze the prevalence and distribution of beta-amyloid deposition in the HIV+ brain in the HAART era. Our working hypothesis is that long term survival, aging and the secondary effects of HAART may contribute to increased beta-amyloid accumulation in this patient population. METHODS: Paraffin embedded archival brain autopsy tissues were assessed by immunocytochemistry for beta-amyloid. Detailed in-vivo neuro-behavioral assessments and ApoE genotyping were available for a subset of the studied population. RESULTS: Immunoreactivity with the antibodies 4G8 and 6E10 was found predominantly in neuronal soma and dystrophic axonal processes. Extracellular, often perivascular plaques were also identified in many cases. CONCLUSIONS: We propose that prolonged HAART and aging may contribute to an overall increase in amyloid deposition, potentially mediated by inhibition of insulin degradation enzyme (IDE) or disruption of the axonal transport of the amyloid precursor protein.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Brains from post-mortem HIV patients display increased levels of deposited Aβ and hyperphosphorylated tau compared to age-matched controls.

    “Moreover, brains from post‐mortem HIV patients display increased levels of deposited amyloid beta (Aβ) and hyperphosphorylated tau compared to age‐matched controls, suggesting pathological links exist between Alzheimer’s disease and HAD (Green et al, 2005; Anthony et al, 2006; Achim et al, 2009).”

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.
