Partial reprogramming induced by the controlled and cyclical overexpression of Yamanaka factors in the nervous system has so far succeeded in reversing some aging-associated phenotypes, such as improving memory function. These promising results suggest that partial reprogramming could be a potential strategy to prevent or mitigate aging-related pathologies like tauopathies, including Alzheimer's disease. Here, we explore the potential of this strategy in addressing tauopathy development in the P301S mouse model. To achieve this, a new transgenic animal was created that can inducibly overexpress Yamanaka factors upon doxycycline administration and carries the Tau-P301S mutation, which leads to tauopathy development. The results of this study show a significant improvement in key pathological features of tauopathies in the hippocampus, including reversed tauopathy, alleviated reactive astrogliosis, age-related reduction of the H3K9me3 epigenetic marker, along with improved spatial memory, which has been described as deteriorated in this model. These findings reinforce the potential of partial reprogramming as a therapeutic strategy to combat brain pathologies associated with aging.
