“…Soluble Aβ 40 and Aβ 42 levels were very low (~an order of magnitude below those of Tg2576 mice [32,33]) at an advanced age (2 0 months), in both cortex and hippocampus. Despite the technical difficulties (some mice were below the limit of sensibility of the ELISA), by comparing the present results with those of our earlier study with a control diet [26], we noticed that Aβ levels are further decreased by HFD. The reason for this is unclear, since previous studies do not support such an inhibitory effect of HFD in 3xTg-AD [41,47] and Tg2576 [48].…”

“…The parental strains used in this study, GFAP-sgp130Fc and 3xTg-AD mice, were generated and characterized previously [24,27,28]. To obtain the 4 genotypes of interest the following crossing strategy was designed, as in [26]. Homozygous 3xTg-AD (+/+) animals were mated with heterozygous GFAP-sgp130Fc (+/−) to obtain the double transgenic 3xTg-AD/GFAP-sgp130Fc (+/−) (+/−) and 3xTg-AD (+/−) (−/−) mice.…”

“…STAT3 expression remained 15 days after surgery correlating with high glial activation and neuronal death. Besides, the classical IL-6 signaling pathway could induce anti-inflammation and a proinflammatory response by trans-signaling; it has been recently studied because of its implication in neurodegenerative disorders, such as amyloid pathology in AD [ 68 , 69 ]. Cytoplasmic STAT3 expression disappeared on day 15 in controls, but AβO rats exhibited nuclear STAT3 expression in hypertrophic glial cells, correlating with persistent neuronal density reduction.…”

“…Several studies on the brain reported that inhibition of IL-6 trans-signaling in microglia and neurons attenuated lipopolysaccharide (LPS)-induced sickness behavior in mice ( Burton et al, 2011 ) and also attenuation of IL-6 trans-signaling mediated neuroinflammation in Alzheimer’s disease models of mice ( Escrig et al, 2019 ). Shi and colleagues reported that elevated IL-6 mRNA levels in activated microglial cells in the PVN contribute to neurogenic hypertension.…”
