Biomarkers. (PubMed, Alzheimers Dement)
The concentrations of cytokines (IL-4, IL-6, IL-8, IL-10 and TGF-β) present in saliva were measured through enzymatic assays (ELISA), using the following kits, respectively: IL-4, IL-6, IL-8, IL-10 - HCYTOMAG-60K-04 CYTOKINE PANEL WITH 04 PLEX (IL4, IL6, IL8 AND IL10); E-EL-H0110 - Human TGF-1(Transforming Growth Factor Beta 1), ELISA Kit We identified important changes in IL-4, IL-6, IL-8 and TGFb1, with increased expression in participants with AD and a reduction in healthy ones, except for TGFb1, which had exactly the same levels found in participants without AD, except for women, where it was increased, a fact to be investigated For IL-10 Cytokines we did not find any type of variation, however IL-8 was elevated in patients with AD and reduced in patients without AD; IL-6, IL-4 and TGF-b are also elevated in AD patients and reduced in healthy subjects. These findings support the hypothesis that AD is an inflammatory process.
