Abstract
In many chronic neurodegenerative diseases including Frontotemporal Dementia and Alzheimer’s disease (AD),
microglial activation is suggested to be involved in pathogenesis or disease progression. Activated microglia secrete a variety
of cytokines, including interleukin-1â, interleukin-6, and tumor necrosis factor as well as reactive oxygen and nitrogen species
(ROS/RNS). ROS and RNS contribute to alterations in neuronal glucose uptake, inhibition of mitochondrial enzymes, a decrease
in mitochondrial membrane potential, impaired axonal transport, and synaptic signaling. In addition, ROS act as signaling
molecules in pro-inflammatory redox-active signal transduction pathways. To establish a high throughput screening system
for anti-inflammatory and neuroprotective compounds, we have constructed an "Enhanced Green Fluorescent protein" (EGFP)
expressing neuronal cell line and set up a murine microglia/neuron co-culture system with these EGFP expressing neuronal
cells. We show that microglia activation leads to neuronal cell death, which can be conveniently measured by loss of neuronal
EGFP fluorescence. Moreover, we used this system to test selected polyphenolic compounds for their ability to downregulate
inflammatory markers and to protect neurons against microglial insult. We suggest that this system might allow accelerated drug
discovery for the treatment of inflammation-mediated neurodegenerative diseases.
