TH and early-onset autosomal dominant Alzheimer disease: In summary, the protein targets identified in Method 2 offer valuable insights into the molecular mechanisms involved in AD + P. By focusing on key proteins, such as integrins, tyrosine hydroxylase, calcium channels, 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, and gamma-aminobutyric acid (GABA) receptors, we can begin to uncover the intricate pathways that may contribute to both the onset and progression of psychosis in Alzheimer’s disease.
