Differential expression of cholinergic enzymes (BCHE
and CHAT) and nicotinic acetylcholine receptors
(CHRNA2 and CHRNA4) in PreC CatD-positive
layer III neurons in AD compared to NCI and MCI. Upregulation trend of
BCHE (AD>NCI, p=0.2t; AD>MCI,
p=0.02t) and CHRNA2 (AD>NCI,
p=0.03t; AD>MCI, p=0.02t) in AD compared to NCI
and MCI. Upregulation trend of CHAT (AD>NCI,
p=0.04t) and CHRNA4 (AD>NCI,
p=0.02t) in AD compared to NCI and significant upregulation of
CHAT(AD>MCI, p=0.005) and CHRNA4
(AD>MCI, p=0.003) in AD compared to MCI. Key: t-trend:
0.01<p<0.05; *: p⩽0.01.
