Measuring cognition in reMYND’s Tau animal models

reMYND’s Tau.P301L and Tau.P301S models feature progressive hyperphosphorylation of Tau with age and a strong correlation of Tau pathology with the motor phenotype. A NFT-like pathology is found in numerous brain regions including brainstem, spinal cord, cortex and hippocampus. In young animals, before the onset of NFT pathology, these models exhibit impaired synaptic plasticity (as assessed by measuring Long Term Potentiation). We have now corroborated these findings by demonstrating a cognitive deficit in both models which precedes the onset of NFT pathology and motor deficit (Figure 1).
