title: [Changes in the immune reaction of animals under conditions of drug-induced activation and blockade of D1 dopamine receptors].
abstract: A highly selective dopamine D1 receptor agonist (compound SKF 38393) administered in a dose of 20 mg/kg produced a significant increase in the number of rosette-forming cells (RFCs) in the spleen of Wistar rats on the 5th day upon their immunization with goat erythrocytes (5 x 10(8)). At the same time, a specific blocker of these receptors (compound SCH 23390) in a dose of 0.5 or 1 mg/kg inhibited the immune response of rats. In C57BL/6J mice, SCH 23390 (0.25, 0.5, or 1 mg/kg) also significantly reduced the number of RFCs. Preliminary blockade of the D1 dopamine receptors with SCH 23390 (1 mg/kg) prevented the immunostimulating effect of SKF 38393. These data indicate that D1 dopamine receptors are involved in immunomodulation.
