Expression in D1R- or D2R-positive striatal neurons. (A) LVs coding for the nuclear DsRed (DsRed2nuc) under the control of Drd1a, Dlx5/6, or Tac1 promoters were injected into the striatum of transgenic BAC-Drd1a-eGFP or Drd2-eGFP mice. Representative images of co-localization of the DsRednuc, with either the Drd1a-eGFP-positive cells or the Drd2-eGFP-positive cells. (B) Quantitative analysis of the co-localization of DsRed2nuc and GFP expression in BAC-Drd1a-eGFP or BAC-Drd2-eGFP mice (n=5–6, except for Drd1a promoter in BAC-Drd2-eGFP mice, n=3). Scale bar=20 μm.
