A Variety of Assays and Experiences in Phenotypic Screening

Case study

Screening for Phagocytosis Modulators using iCell® Microglia AD TREM2

To discover phagocytosis activators using iCell® Microglia AD TREM2 homozygous knockout (iCell Microglia TREM2 HO)cells.

Mutations in the transmembrane protein, TREM2, has become a research focus because of its role in the binding and clearance of Aβ oligomers, thus making it a potential risk factor of Alzheimer’s disease. Elucidation of the mechanism would be useful for development of therapies for Alzheimer’s disease. 

Assay Development
A biologically annotated compound library, consisting of about 3,400 compounds, was tested in a phagocytosis assay using iCell Microglia TREM2 HO to screen for phagocytosis activators.
Compound concentration for the primary screening was set at 3 µM. 

Assay Development Results
We optimized an assay to evaluate cellular uptake activity of fluorescent-labeled Aβ in a 384-well format using InCuCyte® ZOOM. Results showed Aβ uptake kinetics in iCell Microglia TREM2 HO was slower than that of iCell Microglia (wild type, WT).

Screening Cascade Outline

Primary Screen Results
After the primary screening step, false-positive compounds (e.g., auto-fluorescence, cell toxic, and others) were removed. Based on the activity distribution from the primary screening, positive compounds were selected for a following screening cascade, reproducibility assay and concentration-response assay.

Correlation between Aβ uptake activity and cytotoxicity in the primary screening

Correlation between Aβ uptake activity and cytotoxicity in the primary screening

Dose Response Results
We successfully identified several phagocytosis activators. These compounds enhanced phagocytosis activity without severe cytotoxicity.
Representative compounds, A and B, increased the phagocytosis activity in iCell Microglia TREM2 HO comparable to levels of iCell Microglia. Compound A enhanced phagocytosis activity in both iCell Microglia and iCell Microglia TREM2 HO, while compound B increased it only in iCell Microglia TREM2 HO, suggesting that these compounds modulated phagocytosis activity through different mode-of–actions.
