Neurodegenerative diseases are characterized by the degeneration of specific brain areas associated with accumulation of disease-related protein in extra- or intra-cellular deposits. Their preclinical investigations are mostly based on genetically-engineered animals. Despite their interest, these models are often based on high level of disease-related protein expression, thus questioning their relevance to human pathology and calling for the alternate use of ecological models. In the past few years,  Octodon degus  has emerged as a promising animal model displaying age-dependent Alzheimer’s disease-related pathology. As neurodegenerative-related proteins often co-deposit in the brain of patients, we assessed the occurrence of α-synuclein-related pathology in this model using state-of-the-art immunohistochemistry and biochemistry. Despite our efforts and in contrast with previously published results, our study argues against the use of  Octodon degus  as a suitable natural model of neurodegenerative disorder as we failed to identify either Parkinson’s disease- or Alzheimer’s disease-related brain pathologies.

Lack of spontaneous age-related brain pathology in Octodon degus: a reappraisal of the model
