Our findings suggest a model in which PCs synthesize DA through a non-canonical pathway and secrete it in an activity-dependent manner. The released DA binds D1Rs in BGs, inducing membrane depolarization and Ca 2+ signaling and driving membrane insertion of AMPAR GluA1 subunits. These actions may trigger glutamate release from BGs, which then enhances interneuron activity and reduces PF- and CF-PC synaptic transmission by potentially activating presynaptic GluRs. The increased inhibitory and the reduced excitatory inputs to PCs alter their firing frequency and pattern, ultimately impacting locomotor and social behaviors. BG, Bergmann glial cell; GC, granule cell; PC, Purkinje cell; MLI, molecular layer interneuron; CF, climbing fiber; PF, parallel fiber; DA, dopamine; D1R, D1 dopamine receptor; Glu, glutamate.

Experimental design. (A) Schematic diagram of the virus injection area. (B) Experimental design timeline. A total of 336 mice [including 144 <t>D1R-cre</t> mice and 24 wild-type littermate (WT) mice, 144 D2R-cre mice, and 24 WT mice] participated in this experiment. After adaptive feeding for 1 week, they were randomly divided into four large groups (84 mice in each large group), among which 72 <t>D1R-cre</t> mice and 12 WT mice were further divided into two small groups, and 72 D2R-cre mice and 12 WT littermate mice were further divided into two small groups. On the first day, one small group of D1R-cre mice and WT littermate mice, one small group of D2R-cre mice and WT mice were injected with the virus in the bilateral dSTR (200 nL/side), the other two small groups were injected with the virus in the bilateral SNpc (200 nL/side). Eighty-four mice in each large group were randomly divided into 14 groups according to the injections of different drugs or virus, including WT + Vehicle + mCherry + i.p. Saline (group a), D1R or D2R-cre + Vehicle + mCherry + i.p. Saline group (group b), D1R or D2R-cre + Vehicle + Gq + i.p. Saline group (group c), D1R or D2R-cre + Vehicle + Gi + i.p.

Mice in the groups c, f, j, and m were injected with hM3Dq. Mice in group d, g, k, and n were injected with hM4Di. After the virus injection, all mice were back to the cage to rest for 4 days (days 2–5). On days 6–12, mice in groups e, f, g, l, m, and n were intraperitoneally injected with IDPN at 10:00 a.m. once daily, and mice in the other groups were intraperitoneally injected with 0.9% saline (Vehicle, contrast with IDPN). On the 23rd day, mice in the a–g groups were intraperitoneally injected with 0.9% saline (contrast with CNO), and mice in the h–n groups were intraperitoneally injected with clozapine N-oxide (CNO, Sigma, St. Louis, MO, United States, 1 mg/kg). Thirty minutes later, behavioral tests were carried out to compare the differences between the groups. Brain tissues for immunofluorescence labeled were collected on day 24.

    Figure Lengend Snippet: a Heat map of control and D1R cKO mice encountering the empty inverted cup (E) or the cup containing the first novel mouse 1 (S1) or S2 during the three-chamber social test. Minimal and maximum values indicate the relative accumulating activity in each area of the arena. b Time spent in the interaction with E, S1, or S2 ( n = 22 mice, Con: n = 12 mice, Drd1 cKO). Data are presented as mean ± SEM. Unpaired two-sided Student’s t test ( p = 0.0005, Con E vs. S1; p = 0.6135, Drd1 cKO E vs. S; p = 0.0010, Con S1 vs. S2; p = 0.4996, Drd1 cKO S1 vs. S2). c Phosphorylation levels of mTOR in the cerebellum of control and Drd1 cKO mice ( n = 6, each group). Data are presented as mean ± SEM. Mann–Whitney two-sided test ( p = 0.0019, Con vs. Drd1 cKO). d Phosphorylation levels of mTOR in cerebellar slices treated with vehicle (DMSO) for 1 h, SKF83822 for 1 h, or pretreated with SCH23390 followed by SKF83822 for 1 h ( n = 8, each group). Data are presented as mean ± SEM. Multiple unpaired two-sided Student’s t test ( p = 0.0020, Con vs. SKF, p = 0.0096, SKF vs. SCH). n.s., not significant.

    Article Snippet: Sections were permeabilized with 0.25% Triton X-100 for 2 h and blocked with 10% normal goat serum for 1 h. Sections were incubated at 4 °C overnight with blocking solution containing the following primary antibodies: mouse anti-GFAP (1:500, Sigma-Aldrich), rabbit anti-DsRed (1:2000, TaKaRa), mouse anti-RFP (1:1000, Rockland Immunochemicals), mouse anti-D1R (1:200, Sigma-Aldrich), rabbit anti-D1R (1:200, Abcam), mouse anti-DAT (1:200, Thermo Fisher Scientific), rabbit anti-GFP (1:2000, Abcam), chicken anti-GFP (1:2000, Abcam), mouse anti-calbindin D28K (CB) (1:500, Santa Cruz Biotechnology), rabbit anti-N terminal CYP2D6 (1:500; AV41675, Sigma-Aldrich), rabbit anti-C terminal CYP2D6 (1:500; PA5-79129, Thermo Fisher Scientific), mouse anti-TH (1:500, Sigma-Aldrich), rabbit anti-mCherry (1:2000, Abcam), rabbit anti-S100β (1:800, Sigma-Aldrich), guinea pig anti-c-fos (1:800, Synaptic Systems), or guinea pig anti-PV (1:800, Synaptic Systems).

    Our findings suggest a model in which PCs synthesize DA through a non-canonical pathway and secrete it in an activity-dependent manner. The released DA binds D1Rs in BGs, inducing membrane depolarization and Ca 2+ signaling and driving membrane insertion of AMPAR GluA1 subunits. These actions may trigger glutamate release from BGs, which then enhances interneuron activity and reduces PF- and CF-PC synaptic transmission by potentially activating presynaptic GluRs. The increased inhibitory and the reduced excitatory inputs to PCs alter their firing frequency and pattern, ultimately impacting locomotor and social behaviors. BG, Bergmann glial cell; GC, granule cell; PC, Purkinje cell; MLI, molecular layer interneuron; CF, climbing fiber; PF, parallel fiber; DA, dopamine; D1R, D1 dopamine receptor; Glu, glutamate.
