An investigation into the effects of ATV:Trem2 on AD model mice using scRNA-seq
WT hTfR-KI mice and APP/SAA hTfR-KI mice were treated with one of: Isotype control ATV, naked 4D9 (activating Trem2 Ab), or ATV:4D9. Drugs were delivered IV. After 24 hours, mice were sacrificed, and perfused cortices were processed into single-cell suspensions. The suspensions were FACS sorted for Cd45+/Cd11b+ cells. Single-cell suspensions were labeled with CellPlex CMO per 10X Genomics protocol (CG000391 Rev A.) After each sample was labeled with CMO tags, equal numbers of cells per sample were combined into sample pools for single cell capture on the Chromium using Chromium Next GEM Single Cell 3' v3.1 kit. After RT and cDNA amplification, each sample pool was separated into one gene expression (GE) library and one CMO tag library via dual-sided SPRI bead purification. Library preparation was performed per manufacturer's protocol (CG000388 Rev A) Overall design: WT hTfR-KI mice and APP/SAA hTfR-KI mice were treated with one of: Isotype control ATV, naked 4D9 (activating Trem2 Ab), or ATV:4D9.
