Elevated levels of Abeta1-40 and Abeta1-42 do not alter the binding sites of nicotinic receptor subtypes in the brain of APPswe and PS1 double transgenic mice.

Abstract excerpt

The binding sites of nicotinic acetylcholine receptor (nAChR) subtypes were measured in the parietal cortex and hippocampus of transgenic mice carrying mutant human APPswe and presenilin 1 (PS1) genes (APPswe/PS1 mice) between the ages of 3 weeks and 17 months. Soluble and insoluble beta-amyloid peptide (Abeta1-40 and Abeta1-42) levels were investigated in parallel. No significant differences in binding sites of...
