CSF and brain proteomics of Trem2-mKate2 KI/wt.APPSAA/SAA.hTfR KI/KI mice

Triggering receptor expressed on myeloid cells 2 (TREM2) is a central regulator of microglial activity and loss-of-function coding variants are major risk factors for late onset Alzheimer’s disease (LOAD). To better understand the molecular and functional changes associated with TREM2 signalling in microglia, we generated a TREM2 reporter mouse model. Experimental mice expressed the reporter heterozygous while AppSAA and the hTfR knock-in were homozygous (Trem2-mKate2 KI/wt.APPSAA/SAA.hTfR KI/KI) and were treated with the antibody transport vehicle coupled TREM2 agonist antibody ATV:4D9. After the treatment CSF and brain samples were colleceted for proteomics analyses.
