    ..Finally, our results do not support a role of M(1)/M(4) receptors in mediating antipsychotic-like effects of clozapine. ..

    ..These results should aid in the selection of mouse strains for future studies in which D? or D? responsiveness is a necessary consideration in the experimental design. ..

    ..Our results indicate that M5 receptor deletion diminished the reinforcing effects of low doses of cocaine and identified specific conditions under which this may be observed. ..

    ..These findings support the notion that the DAT, but not the SERT, is critical in mediating the reinforcing effects of cocaine. ..

    ..With the possible exception of the D3 antagonist PG01037, no ligand was promising in terms of cocaine addiction treatment. ..

    ..The effect lasted beyond treatment duration and was not dependent upon extinction learning. This suggests that M1/M4 receptor stimulation modulated or reversed some neurochemical effects of cocaine exposure. ..
