There are two major classes of heat-stable microtubule-associated proteins (MAPs): MAP2 and Tau (MAPT).
Tau is expressed in several isoforms in human brain (Tau-A, 2N4R/Tau-F, 1N4R/Tau-E, 0N4R/Tau-D, 2N3R/Tau-C, 1N3R/Tau-B, 0N3R) and rodents (Tau-A, 2N4R/Tau-F, 1N4R/Tau-E, 0N4R/Tau-D) (1). Tau helps to stabilize axonal microtubules and modulate axonal transport, with isoform diversity and phosphorylation status determining their dynamics and affinity for microtubules. Tauopathies, often associated with abnormal phosphorylation (2, 3), can be classified according to the Tau isoforms present in the pathological inclusions. For instance, Pick's disease (PiD) is characterized by tangles containing 3R-Tau isoforms (0N3R, 1N3R, and 2N3R), whereas 4R-Tau (0N4R, 1N4R, and 2N4R) accumulates in disorders like progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD). In Alzheimer's disease (AD) aggregates consist of all Tau isoforms (1).
Tau is abundantly expressed in the central and peripheral nervous system. Compared to the CNS, the PNS shows a predominance of 4R Tau isoforms (0N4R, 1N4R, 2N4R), which are thought to provide stronger microtubule binding and stability needed for long peripheral axons (1, 4).
Since microtubule dynamics are central to cell division, migration, and morphology, aberrations in Tau expression have been implicated in several types of cancer (5). Notably, Tau is increasingly recognized for its role in tumor progression and resistance to cancer therapy, with glioblastoma (GBM), making Tau a potential biomarker and therapeutic target (6,7).
