Abstract

The contribution of immunological factors in the etiopathogenesis of Alzheimer's disease (AD) is increasingly noted. Apart from cerebral immunological findings, peripheral changes of the immune systems have been reported including lymphocyte function and subset distribution. As data still remain inconsistent, we investigated a sample of 43 patients with AD and of 34 healthy age-matched controls. Distribution of the T-, B- and NK cell subsets was determined by flow cytometry (FACS). We found a significant decrease of CD3(+) lymphocytes as well as of CD19(+) lymphocytes. A slight increase of the CD4(+) and a decrease of the CD8(+) subpopulation could be observed, without significant change of the CD4(+)/CD8(+) ratio. CD16(+)56(+) cells were not altered. Our findings of decreased T- and B-Cell numbers in AD sustain the hypothesis of a general decline of immune activity in AD. A putative association with premature immunosenescence in AD and possible pathogenetic implications are discussed.

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?

  • Other reports showed either no correlation or a positive association between peripheral B cell number and AD severity.

    “while other reports showed either no correlation [86] or a positive association [90].”

  • Investigations on proportions and phenotypes of circulating B cells in AD patients compared to age-matched healthy controls have concluded in a significant reduction of both absolute numbers and percentages of blood B cells in AD patients.

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.
