Glutamate Excitotoxicity Assay

Contact us for further information!

Overactivation of glutamate receptors is a fundamental mechanism in neurodegenerative diseases it impairs cellular calcium homeostasis, activates nitric oxide synthesis and generation of free radicals causing programmed cell death.

Excitotoxicity induced by glutamate serves as a dependable model in understanding neurodegenerative diseases such as Alzheimer's disease, Parkinson’s disease, Huntington’s disease, amyotrophic lateral sclerosis (ALS), HIV-associated neurodegenerative disorders, and others. Excitotoxicity emerges as a common pathway in various neurodegenerative conditions, making a functional phenotypic assay an intriguing approach for targeting these diseases.
At our facility, we provide services with this assay using primary frontal cortex cultures or human iPSC-derived tri-cultures comprising glutamatergic, GABAergic neurons, and astrocytes.

Cell Culture: Experiments were performed with primary frontal cortex cultures of mouse. We also offer this assay with human iPSC-derived neuronal cell cultures.
