The following primary antibodies were used for this study: mouse monoclonal anti‐synaptophysin (
SP) (clone SVP38, 1.4 μg/ml, Sigma), guinea pig polyclonal anti
VGlut1 (1:1000, Millipore), rabbit polyclonal anti postsynaptic density 95 (
PSD95, 1 μg/ml, Invitrogen), rat monoclonal anti CD68 (clone FA‐11, 1.4 μg/ml, Bio‐Rad), rabbit polyclonal anti Iba‐1 (1:1000, Wako),
rat monoclonal anti C3 (clone 11H9, 0.5ug/ml, Abcam), and rabbit monoclonal anti C1q (clone 27.1, hybridoma supernatant previously described

FL/FL:Cx3cr1
ERT2) compared with the Arc C1qa
FL/FL at super‐resolution level (Supp Figure
S2) as characterized previously.
