(A) SV2C partially colocalizes with markers for acetylcholine (choline acetyltransferase, ChAT, and the choline transporter, hCHT) in the midbrain (MB) and caudoputamen (CPu). (B) Striatal expression of acetylcholine markers is unchanged following genetic ablation of SV2C. Scale bars = 500 µm (A, MB; B), 100 µm (A, CPu).
