The cholinergic neurons of the human basal forebrain (BFCN) undergo selective loss in neurodegenerative disorders of the elderly, particularly Alzheimer's disease (AD) (Geula and Mesulam, 1999).The loss of these neurons in AD accounts, in part, for the cardinal symptoms of the disease, namely memory loss and attentional deficit.

We used BFCNs derived from . It is generally accepted that the crucial events in the pathogeny of Alzheimer's disease (AD) are the increased accumulation of amyloidogenic peptides derived from amyloid precursor protein and the harmful actions of these peptides on neurons, which bring about neurodegeneration. Recent evidence indicates that the nucleus basalis of Meynert, a distinct population of basal forebrain neurons, is a major source of cholinergic innervation of the cerebral cortex. Some of these neurons depend, however, on trophic support from NGF via a membrane receptor. Artistic illustration comparing the brain of an Alzheimer's patient to a healthy brain. We previously reported that the precursor form of nerve growth factor (pro-NGF) and not mature NGF is liberated in the CNS in an activity-dependent manner, and that its maturation and degradation occur in the extracellular space by the coordinated action of proteases.Here, we present evidence of diminished conversion of pro-NGF to its mature form and of greater NGF degradation in .

Efferents from the Ventral tegmental area and substantia nigra pars compacta. An early substantial loss of basal forebrain cholinergic neurons (BFCNs) is a constant feature of Alzheimer's disease (AD) and is associated with deficits in spatial learning and memory. Brain-derived neurotrophic factor (BDNF) is a member of the neurotrophin family of neurotrophic factors. However, clinical trials with recombinant BDNF have yet to yield success, leading to the suggestion that alternative means of harnessing BDNF actions for therapeutic use may . The cholinergic signaling plays a pivotal role in both structural and functional aspects of spatial memory, i.e., synaptic plasticity and long-term potentiation (LTP) (Hampel et al., 2018).Both cortical and subcortical regions of the brain receive massive cholinergic inputs from basal forebrain cholinergic neurons (BFCNs). The research team led by Isabelle Aubert, PhD, at Sunnybrook Research Institute (SRI) in Toronto, Canada, has successfully used focused ultrasound to permeabilize the blood-brain barrier (BBB) and deliver a compound that stimulates brain cell communication in mice with Alzheimer's diseasepotentially restoring neurons that are vital to learning and memory. However, the mechanisms that contribute to the selective vulnerability of these neurons are not fully delineated. However, the cause leading to A aggregation is not well understood. 1 synonym for neuron: nerve cell.
