The decrease of CD8-positive lymphocytes in Alzheimer's disease

Pirttilä, Tuula, Mattinen, Satu, Frey, Harry·1992·Journal of the Neurological Sciences

Abstract

The aim of this study was to analyze the possible association of the changes in systemic immunity in the neurodegenerative diseases and in brain atrophy per se. Therefore we enumerated the numbers and proportions of the CD3-, CD4- and CD8-positive cells and B-lymphocytes in peripheral blood of 136 patients with various neurodegenerative disorders of the brain and 58 healthy age-matched controls. The selective decrease of the CD8-positive lymphocytes was demonstrated in the patients with Alzheimer's disease. In contrast, in the patients with brain atrophy of unknown origin and in the patients with vascular dementia the number of the CD8-positive cells tended to increase. The results suggest that brain degenerative changes are associated with changes in the systemic immunity and the changes are linked with the underlying disorder more than brain degeneration per se.

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.
