The acetylcholine has been synthesized and stored in a vesicle. We zoom out to see other vesicles inside the terminal bouton, one of the many endings of an axon. These neurons form the septal-hippocampal pathway, a pathway that is important for learning ... IA5. Clinical Application: Acetylcholine and Alzheimer's Disease...

Brain amyloid deposits play a central role in the histopathology of Alzheimer's disease (AD), as evidenced by increased formation of amyloid beta peptides (A beta) in genetic forms of AD that are caused by mutations in the presenilin genes, or the amyloid beta protein precursor (APP) gene. ... 51-84-3 (Acetylcholine)

Amyloid beta(1-42), a major component of amyloid plaques, binds with exceptionally high affinity to the alpha 7 nicotinic acetylcholine receptor and accumulates intracellularly in neurons of Alzheimer's disease brains. ... As in neurons of Alzheimer's disease brains, the alpha 7 receptor in transfected cells was precisely...

The two most significant physical findings in the cells of brains affected by Alzheimer's disease are neuritic plaques and neurofibrillary tangles. Another significant factor in AD is the greatly reduced presence of acetylcholine in the cerebral cortex.

Nicotinic acetylcholine receptors (nAChRs) play a role in a variety of diseases of the central nervous system including Alzheimer's disease (AD) and schizophrenia. There is great interest in evaluating disease-related nAChR changes, and pharmacological treatment of nAChR deficits is a promising therapy.
