The Abeta1-42 peptide is one of the breakdown products of the proteolytic cleavage of the amyloid precursor protein by beta- and gamma-secretases. In biopsy samples of human brain tissue obtained from AD patients and in ectopic systems overexpressing either alpha7 nAChRs or APP, Abeta1-42 coimmunoprecipitates with alpha7 nAChRs (490). The Abeta1-42 peptide also displaces binding of [3H]MLA from alpha7 nAChRs in cerebral cortical and hippocampal synaptosomes (490). PubMed:19126755

Although Aβ peptides negatively alter the cholinergic system at multiple sites, including ACh synthesis, ACh release, and muscarinic receptors (157), the discovery that Aβ1−42 binds to α7 nAChRs with high affinity suggested the potential for a causal role of nAChRs in AD (159, 160).

However, it has been shown that Abeta1–42 binds with high affinity to alpha7 nAChRs in several different neuronal tissues (Wang et al., 2000a) and displaces alpha-bungarotoxin binding (Wang et al., 2000a,b) and, rather than inhibiting receptor internalization, alpha-bungarotoxin enhances internalization of heterologously expressed nAChRs (Kumari et al., 2008).
