ZFP36-mediated ZBP1 degradation inhibits microglia pro-inflammatory and NLRP3 inflammasome activation in Alzheimer's disease.

ABSTRACT: Alzheimer's disease (AD) is a heterogeneous disease with limited treatment efficacy. Identifying novel molecular targets and mechanisms is therefore crucial for developing therapeutic strategies. Zinc finger protein 36 (ZFP36) has not been reported in AD. This study found that the hippocampus of APP/PS1 mice showed ZFP36 upregulation. Using recombinant adeno-associated virus to overexpress ZFP36 improved the cognitive function of APP/PS1 mice, as assessed by Morris maze and Y maze tests. Furthermore, ZFP36 overexpression reduced Aβ deposition, expression of pro-inflammatory markers, and inhibited NLRP3 inflammasome activation in the hippocampus. These inhibitory effects of ZFP36 overexpression on the aforementioned proteins were also observed in Aβ₁₋₄₂-treated BV-2 cells. mRNA sequencing i
