Tau oligomers impair memory and synaptic plasticity through the cellular prion protein by Claudia Balducci, Franca Orsini, Milica Cerovic, Marten Beeg, Beatrice Rocutto, Letizia Dacomo, Antonio Masone, Eleonora Busani, Ilaria Raimondi, Giada Lavigna, Po-Tao Chen, Susanna Leva, Laura Colombo, Chiara Zucchelli, Giovanna Musco, Nicholas M. Kanaan, Marco Gobbi, Roberto Chiesa, Luana Fioriti, Gianluigi Forloni

“…Abstract Deposition of abnormally phosphorylated tau aggregates is a central event leading to neuronal dysfunction and death in Alzheimer’s disease (AD) and other tauopathies. Among tau aggregates, oligomers (TauOs) are considered the most toxic. …”

Interaction between 𝛼-Synuclein and Other Proteins in Neurodegenerative Disorders by Kurt A. Jellinger

“…Despite clinical, genetic, and experimental differences, evidence increasingly indicates considerable overlap between synucleinopathies and tauopathies or other protein-misfolding diseases. Inclusions, characteristics of these disorders, also occurring in other neurodegenerative diseases, suggest interactions of pathological proteins engaging common downstream pathways. …”

Upregulated astrocyte HDAC7 induces Alzheimer-like tau pathologies via deacetylating transcription factor-EB and inhibiting lysosome biogenesis by Jinwang Ye, Suyue Zhong, Huali Wan, Xing Guo, Xuanbao Yao, Qiong Liu, Liming Chen, Jian-Zhi Wang, Shifeng Xiao

“…Conclusions Our findings suggest that upregulation of HDAC7 induces AD-like tau pathologies via deacetylating TFEB and inhibiting lysosomal biogenesis in astrocytes, and downregulating HDAC7-TFEB signaling is promising for arresting AD and other tauopathies.…”

Antibody-mediated degradation of 4R-tau restores mitochondrial membrane polarization in human induced pluripotent stem cell-derived neurons with the MAPT 10+16 mutation by Dale O. Starkie, Charles Arber, Terry Baker, Daniel J. Lightwood, Selina Wray

“…Microtubule-associated protein tau is inextricably linked to a group of clinically diverse neurodegenerative diseases termed tauopathies. The ratio balance of the major tau splicing isoform groups (3 R- and 4 R-tau) is critical in maintaining healthy neurons. …”

Trimeric Tau Is Toxic to Human Neuronal Cells at Low Nanomolar Concentrations by Huilai Tian, Eliot Davidowitz, Patricia Lopez, Sharareh Emadi, James Moe, Michael Sierks

“…Further characterization of tau oligomer species with disease-specific modifications and morphologies is necessary to identify the best targets for the development of biomarker and therapeutic development for AD and related tauopathies.…”

The Microtubule-Associated Protein Tau and Its Relevance for Pancreatic Beta Cells by Magdalena Maj, Gregor Hoermann, Sazan Rasul, Wolfgang Base, Ludwig Wagner, Johannes Attems

“…Structural and biochemical alterations of the microtubule-associated protein tau (MAPT) are associated with degenerative disorders referred to as tauopathies. We have previously shown that MAPT is present in human islets of Langerhans, human insulinomas, and pancreatic beta-cell line models, with biophysical similarities to the pathological MAPT in the brain. …”

Axodendritic targeting of TAU and MAP2 and microtubule polarization in iPSC-derived versus SH-SY5Y-derived human neurons by Breuer Helen, Bell-Simons Michael, Zempel Hans

“…., MAP2 for dendrites and TAU for axons, while the scaffolding proteins AnkG and TRIM46 mark the axon-initial-segment. In tauopathies, such as Alzheimer’s disease (AD), TAU sorting, and neuronal polarity are disrupted, leading to MT loss. …”

Distinct regulation of Tau Monomer and aggregate uptake and intracellular accumulation in human neurons by Amir T. Marvian, Tabea Strauss, Qilin Tang, Benjamin J. Tuck, Sophie Keeling, Daniel Rüdiger, Negar Mirzazadeh Dizaji, Hossein Mohammad-Beigi, Brigitte Nuscher, Pijush Chakraborty, Duncan S. Sutherland, William A. McEwan, Thomas Köglsperger, Stefan Zahler, Markus Zweckstetter, Stefan F. Lichtenthaler, Wolfgang Wurst, Sigrid Schwarz, Günter Höglinger

“…Abstract Background The prion-like spreading of Tau pathology is the leading cause of disease progression in various tauopathies. A critical step in propagating pathologic Tau in the brain is the transport from the extracellular environment and accumulation inside naïve neurons. …”
