Representative picture of a primary culture of cortical neurons immunolabeled with anti-MAP2 antibody

In vitro models

Primary culture of cortical or hippocampal neurons

co-cultured with glial cells (astrocytes and microglia)

  • Amyloid-β1-42 peptide injuries (induced with oligomers of peptide, for information see Callizot et al., 2013)

  • Acute or chronic injuries (microglia activation)

  • Glutamate and NMDA injuries

  • TNF-α injuries / microglia activation

In vivo models

Intra-hippocampal injection of amyloid β1-42 oligomers in aged mice.

Combines the toxicity of amyloid beta oligomers and advanced ageing. Our model mimics the main pathologies of AD: neurodegeneration, activation of pro-inflammatory response, long-term and short-term memory deficit. Validated with donepezil, drug indicated for AD.

ALZHEIMER'S DISEASE

 
Representative picture of a primary culture of dopaminergic neurons immunolabeled with anti-TH antibody

PARKINSON'S DISEASE

In vitro models

Primary culture of mesencephalic neurons (dopaminergic neurons) 

  • Mitochondrial toxins (6-OHDA, MPP+, rotenone) (Callizot et al. 2019)

  • Lysosomal toxin (CBE)

  • α-synuclein oligomers / protofibrils  (neurotoxicity)

Primary culture of mesencephalic neurons with microglial cells

  • α-synuclein oligomers / protofibrils (neuroinflammation)

In vivo models

Currently under validation. Will be based on toxicity of

alpha-synuclein protofibrils.
