IL6 and Alzheimer disease: Results showed that at baseline in those aMCI individuals who did not convert to AD: 1) Aβ1-42 stimulated production of the pro-inflammatory cytokines IL6 and IL1β by CD14+ cells was significantly reduced (p = 0.01), 2) CD14+/IL-33+ cells were increased (p = 0.0004); 3) MFI of TLR8 and TLR9 was significantly increased, and 4) better preserved hippocampus volumes were observed and correlated with IL33+/CD14+ cells.
