Aggregation of big tau disrupts microtubules and causes diastolic dysfunction

Nature Reviews Cardiology, Published online: 17 May 2023; doi:10.1038/s41569-023-00890-2Hyperphosphorylation of tau in the heart reduces the tyrosination of microtubules, leading to myocardial stiffness and heart failure. This novel mechanism of diastolic dysfunction parallels the aggregation of tau in the brain that leads to Alzheimer disease and might be amenable to treatment using monoclonal antibodies against tau.
