Proteína tau como biomarcador en Alzheimer preclínico

Abstract: El desarrollo de biomarcadores de la proteína tau para el diagnóstico temprano de la enfermedad de Alzheimer (EA) emerge como un desafío fundamental, pudiendo mejorar la efectividad de un tratamiento preventivo o que enlentezca la progresión de la enfermedad. Esta revisión analiza las evidencias que justificarían el uso de la proteína tau como biomarcador en Alzheimer preclínico. Para esto se seleccionaron artículos científicos (2011-2021) que incluyeran a la proteína tau en plasma y plaquetas como biomarcador… Show more

“…Physiologically, the tau protein is involved in myelination processes[ 16 , 28 ], regulation of glucose metabolism[ 29 ], rearrangement of microtubules[ 16 ], axonal transport[ 16 ], iron homeostasis[ 16 ], as well as neurogenesis and processes related to learning and memory[ 16 , 28 ]. However, exposure to pesticides may affect the phosphorylation of tau protein and the formation of neurofibrils, resulting in morphological changes in CNS[ 30 , 31 ].…”

“…Tau protein is expressed in six different isoforms: 2N4R, 1N4R, 0N4R, 2N3R, 1N3R and 0N3R, depending on their amino and carboxyl groups. These isoforms come from the alternative cutting and splicing of the microtubule associated protein tau ( MAPT ) gene located on position q21 of chromosome 17[ 16 , 28 ]. Tau is a 441-amino acid hydrophilic protein sub-classified into 4 domains.…”
