The protein levels of IL-1β (Figure 5A), IL-6 (Figure 5B), and TNF-α (Figure 5C) were significantly increased in AD mice (Figure 5Ab, 5Bb, 5Cb, 5Ae, 5Af, 5Be, 5Bf, 5Ce, 5Cf) and decreased in PAW-fed (AD+PAW) (Figure 5Ac, 5Bc, 5Cc, 5Ae, 5Af, 5Be, 5Bf, 5Ce, 5Cf) and FMT (AD+FMT) (Figure 5Ad, 5Bd, 5Cd, 5Ae, 5Af, 5Be, 5Bf, 5Ce, 5Cf) AD mice compared to water-fed AD mice (Figure 5Aa, 5Ba, 5Ca, 5Ae, 5Af, 5Be, 5Cf, 5Ce, 5Cf), as measured by an IF staining assay (Figure 5A–5C). This evidence concerns the gene IL1B and Alzheimer disease.
