[Activation of dopaminergic system stimulates an immune response in mice with opposite type of behaviour].
It was shown that activation of dopaminergic (Daergic) system induced an increase of the immune responsiveness independent of the CBA mice behaviour typeanimals without experience of victories and defeats (control), with aggression and submission. Administration of SKF-38393, a selective agonist of DA D1-receptors, resulted in enhanced immune response as tested by plaque-forming cells and rosette-forming cells number. Similar immunostimulation was observed after injection of p-chlorophenylalanine realizing its influence on the immune response through DA D2-receptors as shown by us elsewhere. It was suggested that activation of Da-ergic system produces a new neurochemical pattern (Daergic neurochemical set) which are responsible for character and intensity changes of the immune response in mice with alternative form of social behaviour.
