abstract = {We used an inducible mouse model expressing the Tau repeat
domain with the pro-aggregant mutation ΔK280 to analyze
presynaptic Tau pathology in the hippocampus.Expression of
pro-aggregant Tau(RDΔ) leads to phosphorylation,
aggregation and missorting of Tau in area CA3. To test
presynaptic pathophysiology we used electrophysiology in the
mossy fiber tract. Synaptic transmission was severely
disturbed in pro-aggregant Tau(RDΔ) and Tau-knockout mice.
Long-term depression of the mossy fiber tract failed in
pro-aggregant Tau(RDΔ) mice. We observed an increase in
bouton size, but a decline in numbers and presynaptic
markers. Both pre-and postsynaptic structural deficits are
preventable by inhibition of Tau(RDΔ) aggregation. Calcium
imaging revealed progressive calcium dysregulation in
boutons of pro-aggregant Tau(RDΔ) mice. In N2a cells we
observed this even in cells without tangle load, whilst in
primary hippocampal neurons transient Tau(RDΔ) expression
alone caused similar Ca(++) dysregulation. Ultrastructural
analysis revealed a severe depletion of synaptic vesicles
pool in accordance with synaptic transmission impairments.We
conclude that oligomer formation by Tau(RDΔ) causes pre-
and postsynaptic structural deterioration and Ca(++)
dysregulation which leads to synaptic plasticity deficits.},
