Tau is always associated with Alzheimer's disease. Holly Firfer has more. El Papel de la Proteína Tau en la Enfermedad de Alzheimer 14 de abril de 2009 Unos investigadores del Instituto Max Planck para la Química Biofísica, en Gotinga, y sus colaboradores han examinado qué módulos de la proteína Tau pueden actuar de manera destructiva en neuronas de pacientes que sufren la enfermedad de Alzheimer. Consequently, tau deposits have become a target for determining the progression and treatment of AD. Furthermore, the tau hypothesis states that an excessive or abnormal phosphorylation of tau disassembles microtubules and sequesters normal tau, microtubule associated protein1 (MAP1), MAP2, and ubiquitin into tangles of paired helical filament. The authors suggest that the reason tau becomes modified is to protect from damage caused by amyloid protein aggregation. A protein called kinase p38γ phosphorylates tau at the threonine-205 amino acid.

Then, tau becomes misfolded and the protein begins to aggregate, which eventually forms the neurofibrillary tangles seen in Alzheimer’s patients.

Under normal circumstances, tau is a microtubule-associated protein (MAP) involved in microtubule stabilization. Recently, several tau PET tracers including T807, THK-5117, and PBB3 have been developed and succeeded in imaging neurofibrillary pathology in vivo. For use of tau PET as a biomarker of tau pathology in Alzheimer's disease, PET tracers should have high affinity to PHF-tau and high selectivity for tau over amyloid-β and other protein deposits. Research into Alzheimer's disease has long focused on understanding the role of two key proteins, beta amyloid and the tau protein. Found in tangles in patients' brain tissue, a pathological form In healthy neurons, tau normally binds to and stabilizes microtubules.

Det finns inga specifika blodprover som kan påvisa Alzheimers sjukdom. Ett sätt att se vad som händer i hjärnan är att studera likvor.

Proteinet tau är sedan länge kopplat till alzheimer. Redan i ett tidigt skede av sjukdomen ansamlas tau inne i hjärncellerna. Det påverkar cellernas funktioner så att minnet försämras. Tau är därför av stort intresse för forskningen, i synnerhet när nya vaccinastionstester ska genomföras. Tau Tau is a protein that helps stabilize the internal skeleton of nerve cells (neurons) in the brain. This internal skeleton has a tube-like shape through which nutrients and other essential substances travel to reach different parts of the neuron. In Alzheimer’s disease, an abnormal form of tau builds up and causes the internal skeleton to fall Abnormal phosphorylation of tau is known to contribute to Alzheimer's disease pathology, with approximately 45 specific phosphorylation sites identified in the Alzheimer's disease brain 39,40.
