Oxidative Stress and the Thromboxane Receptor–A Central Pivot in the Production of Neurofibrillary Tangles and Amyloid-beta
By Ralph Sanchez, MTCM, CNS, D.Hom.
New research published Oct. 13 by the journal Neurobiology of Aging revealed that the free radicals produced during oxidative stress bind to a protein receptor in the brain designated as “the Thromboxane Receptor A2 (TP)”. The study, “Modulation of AD Neuropathology and Memory Impairments by the Isoprostane F2α Is Mediated by the Thromboxane Receptor” demonstrated that oxygen free radicals actually bind to TP, and transmit signals to neuronal cells to increase the production of amyloid beta, and Neurofibrillary Tangles (abnormal phosphorylated microtubule-associated protein tau), the two major pathological lesions associated with Alzheimer’s disease.
