Abstract

Inflammation has been involved in the development of dementia in cerebrovascular diseases. To investigate the cellular activation of the peripheral immune system in patients with Alzheimer's disease (AD) and vascular dementia (VaD), we determined the presence of IL-18 and TGF-beta1 in the plasma by using ELISA. The levels of IL-18 and TGF-beta1 were significantly elevated in patients with AD and VaD compared to non-demented, age-matched subjects. We found an inverse correlation between the levels of IL-18 and TGF-beta1 in AD patients. In VaD patients, the correlation between IL-18 and TGF-beta1 reached a borderline positive value. Whereas, in the non-demented, age-matched subjects, a positive correlation between IL-18 and TGF-beta1 levels was observed. These findings indicate that IL-18 and TGF-beta1 elevation is associated with AD and VaD patients, confirming that the immune system might exert a remarkable role in the development and progression of neurodegenerative disorders. Moreover, as different modifications were detected in the patients affected by AD and VaD, we propose that IL-18 and TGF-beta1 plasma levels might represent possible differential biomarkers.

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.
