WebApr 12, 2024 · Abnormal expression of Tau protein can cause the development of Alzheimer’s disease (AD). So far, much evidence has demonstrated that Tau has multiple isoforms. These isoforms are suggested to have distinct physiological roles and contribute unequally to the progress of AD. Thus, detection of individual Tau isoforms may be … WebApr 5, 2024 · The tauopathies are a diverse group of neurodegenerative diseases that are defined by the misfolding of tau—a microtubule binding protein—and its assembly into filamentous intracellular deposits. Primary tauopathies, in which tau inclusions are the principal pathological hallmark, highlight the neurotoxic nature of tau. In Alzheimer's …
