MAPT and Alzheimer disease: This might help researchers to gain insights into the pathogenesis of AD and develop novel strategies for treatment and prevention of the disease, for example, the production of more sensitive and specific nanoparticles for the detection of Aβ peptides and tau protein in the brain or the enhancement of non-invasive techniques, such as imaging, new biomarkers, and metabolic assays, to offer rapid, precise, and early indication of the disease.
