    Abstract:
    Development of depressive-like state in mice of the C57BL/6J strain is accompanied by a considerable decrease in the immune response. A selective activation of presynaptic 5-HT1A-receptors (8-OH-DPAT, 0.1 mg/kg, for 15 min before immunization) markedly increased the immune response tested with the number of IgM-antibody-forming cells, and stimulation of postsynaptic 5-HT1A-receptors (8-OH-DPAT, 1.0 mg/kg, for 30 min before immunization twice) produced an immune suppression in control animals (mice without experience of victories and defeats). On the other hand, there were no changes in the immune response level following 8-OH-DPAT administration (0.1 and 1.0 mg/kg) in mice with depressive-like state. The role of pre- and postsynaptic 5-HT1A-receptors in immunomidulation in mice with depressive-like behaviour is discussed.
