WebMany studies have shown the loss of acetylcholine in the AD brain. Further investigations revealed decreased levels of choline acetyltransferase (CAT) . In addition, it is noted that neurons are lost in the nucleus basalis of the Meynert (nBM), a region of the brain that receives diffuse cholinergic projection . Acetylcholine is synthesized in certain neurons by the enzyme choline acetyltransferase from the compounds choline and acetyl-CoA. Cholinergic neurons are capable of producing ACh. An example of a central cholinergic area is the nucleus basalis of Meynert in the basal forebrain. The enzyme acetylcholinesterase converts acetylcholine into the inactive metabolites choline and acetate. This enzyme is abundant in the synaptic cleft, and its role in rapidly clearing free acetylcholine fr… images of pot belly pigs
