A Mechanism Study of NMDAR1 in A Rat Alzheimer Disease (AD) Model

ABSTRACT This study aimed to investigate the expression and mechanism of N- methyl -D- aspartate receptor 1 (NMDAR1) in the pathogenesis of Alzheimer disease (AD). Eighty adult Wistar rats were randomly divided into 4 groups (n=20 each) to receive an injection of 0, 5, 7 and 10 μl of 1 μg/μl amyloid-β 42 (Aβ1-42) in the hippocampus. Twenty rats in normal control group were injected with equal volume of saline. After 10 days, the hippocampus was isolated from 5 randomly selected rats in each group. The NMDAR1 protein and mRNA expression was determined by immunohistochemical staining and qR...
