Effects of DNLA on Aβ25−35-induced neuronal Nissl bodies in the hippocampus and cortex. Sections of the hippocampus CA3 region and cortex were obtained and stained with Nissl staining (400×). (A–C) showed the CA3 hippocampal cyto-architecture of mice in sham, model and DNLA groups, respectively; (D–F) showed the cortical cyto-architecture of mice in the sham group, model group and DNLA groups, respectively.
