Emerging studies suggest a role for tau in regulating the biology of RNA binding proteins (RBPs). We now show that reducing the RBP T-cell intracellular antigen 1 (TIA1) in vivo protects against neurodegeneration and prolongs survival in transgenic P301S tau mice. Biochemical fractionation shows co-enrichment and co-localization of tau oligomers and RBPs in transgenic P301S tau mice. Reducing TIA1 decreases the number and size of granules co-localizing with stress granule markers. Decreasing TIA1 also inhibits the accumulation of tau oligomers at the expense of increasing neurofibrillary tangles (NFTs). Despite the increase in NFTs, TIA1 reduction increases neuronal survival and rescues behavioral deficits and lifespan. These data provide in vivo evidence that TIA1 plays a key role in mediating toxicity, and further suggest that RBPs direct the pathway of tau aggregation and the resulting neurodegeneration. We propose a paradigm in which dysfunction of the translational stress response leads to tau-mediated pathology.
