ALZHEIMER'S DISEASE PREPARED BY: GROUP A RIPHAHINTERNATIONAL UNIVERSITY 2. The study of neurodegenerative diseases using pluripotent stem cells requires new methods to assess neurodevelopment and neurodegeneration of specific neuronal subtypes. 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). In 1998, Rusty Gage, a neuroscientist at the Salk Institute, and colleagues examined postmortem human brains and discovered evidence of adult neurogenesis in the hippocampus, the brain center associated with learning, memory, and emotional responsesseveral of . The susceptibility to degeneration of a subset of neurons, known as basal forebrain cholinergic neurons (BFCNs), in DS and AD is a critical link between cognitive . 1) In terms of the neuropathological features of memory loss and cognitive dysfunction, cholinergic deficits and neuronal dysfunction have been considered to be the primary causes as observed in patients with AD.

Because ACh has an important role in cognitive processes, the cholinergic system is pointed as an important factor in many forms of dementia, including AD [ 179, 180 ]. The neuronal nicotinic receptors (nAChRs) are involved in several processes in brain including nicotine dependence and cognitive disorders. is a progressive neurodegenerative disease. 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. Tropomyosin receptor kinase A, focused ultrasound, basal forebrain cholinergic neurons, Alzheimer's disease, transgenic mice. -amyloid (A) is widely accepted to be one of the major pathomechanisms underlying Alzheimer's disease (AD), although there is presently lively debate regarding the relative roles of particular species/forms of this peptide.

We developed a . Injury or insult to the adult nervous system often results in reactivation of signaling pathways that are normally only active during development. Induced pluripotent stem cells (iPSCs) derived from patients with AD as well as from normal controls could be efficiently differentiated into neurons with characteristics of BFCNs.
