Evidence of sexual dimorphism in D1 and D2 dopaminergic receptors expression in frontal cortex and striatum of young rats.

D1 and D2 receptors are key mediators of dopaminergic signaling in the brain, and since the manifestations of pathologies related to dopamine are different in female and male patients, it is important to analyze if there are sex-related differences in dopaminergic markers. To contribute to the knowledge in this regard, the objective of this report was to characterize the particular expression level of D1 and D2 dopamine receptors in young male and female rats. Striatum (STR) and frontal cortex (CTX) were obtained from intact 30-days old animals, and the D1 and D2 expression level was analyzed by Western blot.
