In vivo axonal transport deficits have been reported prior to plaque pathology in mouse models of Alzheimers disease. However, there are limited in vivo measurements of axonal transport in models of other neurodegenerative diseases such as frontotemporal dementia (FTDP-17). In the r(tta)Tg4510 mouse model, the P301L tau mutation is conditionally expressed throughout the forebrain. In this study, we characterized 10 month old r(tta)Tg4510 mice and found significant deficits in axonal transport in olfactory neurons. This study provides a basis to characterize earlier time points in the r(tta)Tg4510 mouse model in order to investigate therapeutic interventions in this mouse model.
