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.

Transmission Characteristics of Variably Protease-Sensitive Prionopathy


* We concluded that VPSPr is transmissible; thus, it is an authentic prion disease.

National Prion Disease Pathology Surveillance Center Cases Examined1 (October 7, 2014)


***6 Includes 11 cases in which the diagnosis is pending, and 19 inconclusive cases;


***7 Includes 12 (11 from 2014) cases with type determination pending in which the diagnosis of vCJD has been excluded.


***The sporadic cases include 2660 cases of sporadic Creutzfeldt-Jakob disease (sCJD),


***50 cases of Variably Protease-Sensitive Prionopathy (VPSPr)


***and 21 cases of sporadic Fatal Insomnia (sFI).
