WebIn tau transgenic mice, deficiency in Cx3cr1 leads to activation of microglial cells and tau pathology progression in terms of protein aggregation ( Maphis et al., 2015 ). In alternative study, Cx3cr1 knockout AD mouse … WebHow microglia activation contributes to tau toxicity remains largely unknown. Here we show that nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling, activated by tau, drives microglial-mediated tau propagation and toxicity. Constitutive activation of microglial NF-κB exacerbated, while inactivation diminished, tau ...

We previously demonstrated the crucial deleterious role of Gal-3 in microglial activation in Alzheimer’s disease (AD). Under AD conditions, Gal-3 is primarily expressed by microglial cells clustered around Aβ …
WebMicroglia proliferation was assessed by measuring IBA1 expression with an immunofluorescence assay (Cuitavi, Lorente, et al., 2024), since IBA1 is considered a marker for microglial activation (Lier et al., 2024).
