In our study, the used rat model increased Aβ in the hippocampus to promote M1 phenotype activation abetted by the increased NLRP3, which was validated by the increased activity of NOS2 and nitrated Aβ, as well as the upregulation of Iba-1 expression in the current hippocampal sections of AD rats, consistent with a previous finding (Heneka et al. 2013). The gene discussed is NLRP3; the disease is Alzheimer disease.
