Abstract
Our aims are to review animal models of tauopathies, which include a number
of brain disorders with various aetiologies, including aging, genetics,
infectious diseases, toxins, trauma, and other unknown factors. Tauopathies are
characterised by the accumulation of filaments of the microtubule-associated tau
protein. The different aetiopathogeneses and distinct molecular events involved
in tau aggregation have led to the development of various animal models for
these diseases.
In this review, rather than listing all current models, we focus on
specific animal models addressing, among others, the question of tau
hyperphosphorylation, tau aggregation and tau spreading. Physiological
conditions, including normal aging and hibernation, may exhibit tau
phosphorylation and some aspects of tauopathies. However, most of the models of
tauopathies involve genetically modified animals (mostly rodents, but also fruit
fly, zebrafish, and worm). Some of these models have been crucial for the
development of therapeutic approaches in humans.
The present review shows the difficulty in pinpointing a specific mechanism
that may be targeted in tauopathies but also opens up new avenues for innovative
therapeutic strategies.
