SLC17A7 and Alzheimer disease: Since VGlut1 puncta is increased in Arc‐C5aR1KO (compared to Arctic mice) but there is no difference in % C1q puncta, our results suggest that although C1q tagging plays a role in presynaptic pruning in this AD mouse model, the presence of C1q puncta is not sufficient to lead to ingestion of synapses.
