Figure 4From: A coimmunization vaccine of Aβ42 ameliorates cognitive deficits without brain inflammation in an Alzheimer’s disease modelCoimmunization suppressed the expression of inflammatory cytokines in the brains of amyloid precursor protein 695 transgenic mice. Protein lysates were prepared from the brains of wild-type (WT), amyloid protein precursor 695 (APP695) and vaccinated mice 7 days after the fifth immunization (n = 5). The expression of cytokines was determined by cytometric bead array. Levels of interferon γ (IFN-γ), tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β) and IL-6 were analyzed, and mean ± SD values are expressed as picograms per 100 milligrams of brain tissue. Statistical analysis was performed using parametric one-way analysis of variance, and t-tests were used to compare two groups. *P < 0.05 compared with APP695 mice. co-Aβ42, APP695 mice immunized with co-amyloid-β42 vaccine; pro-Aβ42, APP695 mice immunized with amyloid-β42 protein vaccine.Back to article page
