Abstract

The microtubule-associated protein tau oligomerizes, but the actions of oligomeric tau (oTau) are unknown. We have used Cry2-based optogenetics to induce tau oligomers (oTau-c). Optical induction of oTau-c elicits tau phosphorylation, aggregation, and a translational stress response that includes stress granules and reduced protein synthesis. Proteomic analysis identifies HNRNPA2B1 as a principle target of oTau-c. The association of HNRNPA2B1 with endogenous oTau was verified in neurons, animal models, and human Alzheimer brain tissues. Mechanistic studies demonstrate that HNRNPA2B1 functions as a linker, connecting oTau with N 6-methyladenosine (m 6 A) modified RNA transcripts. Knockdown of HNRNPA2B1 prevents oTau or oTau-c from associating with m 6 A or from reducing protein synthesis and reduces oTau-induced neurodegeneration. Levels of m 6 A and the m 6 A-oTau-HNRNPA2B1 complex are increased up to 5-fold in the brains of Alzheimer subjects and P301S tau mice. These results reveal a complex containing oTau, HNRNPA2B1, and m 6 A that contributes to the integrated stress response of oTau.

  • The lamin nucleoskeleton becomes destabilized in neurons of transgenic Drosophila expressing pathogenic forms of tau, in tau transgenic mice, in human brains from patients with AD or FTD due to MAPT mutation, in induced pluripotent stem cell-derived neurons carrying MAPT mutations, and in cells with induced tau expression or aggregation.

    The Results section, “Tau oligomerization elicits disruption of the nuclear envelope” (page unavailable), reports LaminB2 redistribution and insolubility in neurons with induced tau oligomerization, as well as nuclear-envelope disruption in P301S tau mice. It does not establish the claimed lamin destabilization in Drosophila, human AD or MAPT-related FTD brains, or MAPT-mutant induced pluripotent stem cell–derived neurons. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
