The deposition of ß-amyloid peptides and the accumulation of neurofibrillary tangles, together with the activities of acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and lipoxygenases (LOX) enzymes, have demonstrated crucial roles in neurological disorders, regulating the cholinergic system and participating in neuroinflammatory responses [17]. The gene discussed is BCHE; the disease is nervous system disorder.
