Aged Mice- Not Young But Relevant

Aged mice: available models


Aged mice related models are based on animals that begin to exhibit cognitive, biochemical and brain metabolism deficits starting at approximately 12 months of age.


These models can be used to assess efficacy in age-related cognitive decline associated with Parkinson’s, Alzheimer’s diseases and other diseases linked with aging. These studies can also be combined with other models such as scopolamine-induced amnesia.


Aging Research:Introducing Not Young But Relevant


The need for better animal models in aging preclinical research is based on the necessity to reduce first clinical phases high attrition rate. Indeed, how does one explain the discrepancy between positive preclinical results and failure in early clinical phases? The translation value is too low.

Our answer: animal models need to better mimic the development of the human disease.



Not Young But Relevant: better models for Parkinson’s disease

Our new available models for Parkinson’s disease integrate the major known risk factors in the development of the disease:

  • age (>12 month old)
  • inflammation (LPS)
  • toxins (MPTP)
  • genetics (α-synuclein. PAC-Tg(SNCAWT); Snca-/- mice)
  • western diet (oxidative stress)
  • gender


Behavioral (Pole test, Rota-Rod test, Force Swim test, Social Recognition test, Open field activity test…)  as well as histology studies show that these models correctly recapitulate the physiopathology of the human disease. In particular, we observed in old animals, after LPS triggered inflammation and MPTP chronic treatment, the formation of α-synuclein aggregates and a reduction in Tyrosine Hydroxylase positive neurons.

We anticipate that these animal models will prove useful to better predict human response to tested items.
