The most commonly prescribed treatments for AD are acetylcholinesterase inhibitors, which decrease the hydrolysis rate of ACh and, thereby, enhance cholinergic signaling. One such drug, galantamine (Reminyl), also potentiates nAChRs (66). PubMed:17009926

Recently, the novel non-selective antihistamine dimebon (2,3,4,5-tetrahydro2,8-dimethyl-5–2[-6methyl 3-pyridnyl)ethyl]-1H-pyrido[4,3-b] indole) was shown to inhibit BChE and AChE, block the NMDA receptor signaling pathway, inhibit mitochondrial permeability and provide neuroprotective effects in models of AD [194].

Specifically, progressive phenotypic downregulation of markers within CBF neurons as well as frank CBF cell loss has been observed consistently, along with an associated reduction of choline acetyltransferase (ChAT) and acetylcholinesterase (AChE) activity within the cortex in AD [16]. Most researchers presumed that progressive disruption of cholinergic function underlies much of the short-term memory loss seen in AD PubMed:18986241

Butyrylcholinesterase (BChE) is a serine hydrolase similar to AChE that is widely distributed throughout the CNS and also catalyzes the hydrolysis of ACh. BChE is localized to neurons and glia, and is associated with NFTs and senile plaques (SPs) in AD brain [32]. Interestingly, population-based genetic studies of AD have identified a point mutation that changes Ala539 to threonine in the K variant of BChE, which effectively reduces serum BChE concentrations, and may be associated with cognitive decline [33]. BChE activity also increases in AD brain whereas AChE activity remains unchanged or declines [34,35]. PubMed:18986241

For example, the vesicular ACh transporter (VAChT), which is co-expressed with ChAT in human CBF neurons and participates in loading ACh into synaptic vesicles in cholinergic terminals, is not severely altered in AD [40]. In this regard, pharmacological studies of VAChT in postmortem AD tissue or in vivo imaging studies using vesamicol and its analogs, suggest that VAChT levels remain steady or are minimally decreased coincident with a severe decline in ChAT activity in cortical areas [41].

In this regard, AChE has been localized to SPs in the vicinity of cholinergic synapses, and experimental evidence suggests that AChE promotes Ab fibrillization [164], suggesting that a further benefit from AChE inhibitor therapy may be to prevent continued Ab deposition in cholinergic projection sites.

It is likely that the therapeutic benefit of cholinesterase inhibitors occurs at least in part through activation of the nAChRs, by the direct action of increased levels and/or through a direct activation of the allosteric site on the nAChR (Maelicke et al 1995, 2000) PubMed:11230871

Since an enhanced activity of acetylcholinesterase has been measured in cerebrospinal fluid following long-term treatment with tacrine (Nordberg et al 1999), possibly as a result of an increased acetylcholinesterase gene expression, it might be an advantage to use drugs interacting with nAChRs PubMed:11230871

p(HGNC:ACHE) decreases a(CHEBI:acetylcholine) View Subject | View Object

Several lines of evidence point to a link between brain nAChRs and the development of AD. Biochemical analysis of brains of patients with AD reveals deficits in nAChRs, an increase in butyrylcholinesterase, reduction in ACh, and attenuated activity of cholinergic synthetic [choline acetyltransferase (ChAT)] and inactivating (AChE) enzymes (Bartus et al., 1982; Francis et al., 1999).Butyrylcholinesterase and AChE help terminate ACh signaling by hydrolyzing the transmitter, thereby inactivating it.

Unlike many neurotransmitter signals that are shaped by pumps that return the transmitter to the intracellular space, the spread of ACh from the release site is determined by diffusion and by acetylcholinesterase (AChE) hydrolysis of ACh. PubMed:17009926

Another important aspect of this diffusive ACh signal is that its eventual hydrolysis creates choline, which also activates and desensitizes nAChRs in a subtype-selective manner (54, 55). PubMed:17009926

Indeed, cholinergic enhancement (via cholinesterase inhibition) reopens the critical period for visual acuity in adult wild-type mice (Morishita et al., 2010), indicating that cellular mechanisms for robust plasticity are maintained in adulthood through the cholinergic system but are suppressed by the action of lynx.
