    Alomone Labs anti d2r antibody
    The effects of D1-D2 heteromer stimulation and inactivation on basal conditioned place preference. (A) Vehicle-conditioned rats did not exhibit a preference toward a particular chamber. D1-D2 heteromer stimulation by SKF 83959 (1.5 mg/kg, s.c.) induced conditioned place aversion (CPA) as the animals spent significantly less time in the drug paired chamber. (B) SKF 83959-induced CPA was abolished by pre-treatment by the D1-D2 heteromer selective disrupting peptide, TAT-D1, but not the control TAT-Sc peptide. (C) Inactivation of D1-D2 heteromer by TAT-D1 resulted in conditioned place preference (CPP) as the rats spent significantly more time in the drug paired chamber, not observed with the control TAT-Sc. (D) Representative western blots (inset) and histogram showing the amount of D1R co-immunoprecipitated with <t>D2R</t> from the NAc of rats treated with saline or SKF 83959. Pretreatment with TAT-D1 led to decreased co-immunoprecipitated receptors. An aliquot of each sample was used as a control for WB (input control). (E,F) The CPA induced by D1-D2 heteromer stimulation was abolished by Cdk5 inhibitor roscovitine pre-treatment (200 nmol, i.c.v, E ) or intra-accumbal injection (30 nmol, F ). (G) Representative western blot and histogram showing the density of Thr75-DARPP-32 phosphorylation (pT75) relative to GAPDH (as loading control). Data represent means ± SEM of n = 8–10 rats/group. ( * p < 0.05, ** p < 0.01: compared to saline).

    Signaling pathways involved in D1-D2 heteromer modulation of cocaine-induced behaviors: DARPP-32, ERK and ΔFosB. (A) Representative immunoblots of pT34-DARPP-32 (top panel) or pT75-DARPP-32 (lower panel) obtained from NAc of rats conditioned with saline or cocaine (10 mg/kg, i.p.) and injected on the test day with saline or SKF 83959. Loading controls (GAPDH) are shown. Quantification of pT34- and pT75-DARPP-32 immunoblots is shown. (B) Representative immunoblot of pERK44/42 obtained from the NAc of rats conditioned as in (A) is shown. Quantification of pERK44/42 immunoblots obtained from all animals is shown. Results in (A,B) represent the mean ± SEM from 8 to 9 rats/condition. * p < 0.05 and ** p < 0.01 represent significant differences from control. (C) Representative confocal images of pERK assessed in the three types of MSNs: D1R-only (red arrow), Enk-only (D2R, green arrow) or D1R and ENK (D1-D2 heteromer)-expressing neurons (yellow arrow) in MSNs from NAc of saline- or SKF 83959-treated rats. (D) Quantification of pERK fluorescence in MSNs in the NAc. Results are the mean ± SEM of data after removing the non-specific background ( n = number of MSNs from N = at least 3 rats/condition). ( ** p < 0.001; *** p < 0.0001). (E) Representative immunohistochemistry images and their quantification obtained using an antibody against ΔFosB and a secondary antibody conjugated to Alexa-488. Nuclei are stained by DAPI. Rats were treated for 7 days with cocaine (10 mg/kg, i.p.) without or with co-injection of SKF 83959 (1 mg/kg, s.c.). Disrupting the heteromer by repeated injections of TAT-D1 had the same effect as repeated injections of cocaine. Results are means ± SD obtained by the analysis of n = 1,500–1,700 neurons from the NAc of N = 3 rats/condition.
