In normal rats, impaired memory of a learned behavior was observed after intraventricular application of soluble oligomers of Aβ42 isolated directly from human AD brains (Shankar et al. 2008). Furthermore, AβO injections resulted in reduction of a synapse number and their function in dose-dependent manner. It also led to the inhibition of LTP and enhancement of long-term synaptic depression (LTD) in rodent hippocampus (Shankar et al. 2008). PubMed:29196815

In receptors harboring the gamma subunit, agonist-induced receptor activation results in a long-lasting open channel time. The large agonist-induced current in turn leads to local intermittent depolarization and adjustments to protein-protein interactions that favor receptor clustering. As the depolarization increases, transcription of the epsilon subunit is increased dramatically (183). PubMed:19126755

Consequently, there is mounting evidence that Abeta affects cholinergic signaling independent of its cytotoxic action. For example, Abeta blocks long-term potentiation, a cellular correlate of learning, through activation of JNK and p38MAPK (Wang et al., 2004). PubMed:19293145

M1 mAChRs have been demonstrated to potentiate NMDA-receptor signaling in the hippocampus and cortex,48,49 brain areas intimately associated with learning and memory.

Among the mAChR family members, the M1 subtype makes up 50–60% of the total and is predominantly expressed in all major areas of the forebrain, including the hippocampus, cerebral cortex, corpus striatum, and thalamus[36-38]. M1 mAChR-knockout mice show a series of cognitive defi cits and impairments in long-term potentiation, indicating that the M1 subtype is physiologically linked to multiple functions such as synaptic plasticity, neuronal excitability, neuronal differentiation during early development, and learning and memory PubMed:24590577
