文摘

Antipsychotic drugs (APDs) that bind mainly to the dopamine D2 receptor or the type II 5-HT receptor have been used to ease the symptoms of schizophrenia. Several studies have reported that APDs can also regulate the immune response. Dendritic cells (DCs) are the major antigen-presenting cells in the immune system. DCs can release 5-HT and dopamine to modulate T-cell activation and differentiation. In this study, we use the monocyte-derived DCs to investigate the drug effects of typical APD (haloperidol) and atypical APD (risperidone) on DCs in vitro. Our studies revealed that only risperidone but not haloperidol affected the cytokine and chemokine production of mature DCs. Risperidone increased the production of IL-10 and MDC as well as the proinflammatory cytokines, such as IL-6, IL-8, and TNF-¦Á, but decreased the production of IP-10 and IL-12. Furthermore, the exposure of DCs to risperidone led to lower IFN-¦Ã production by T-cells. The results suggested that risperidone can modulate the DCs' immune function by inhibiting the potent Th1 cytokines and increasing the potent Th2 cytokines. In addition, the production of TNF-¦Á by risperidone-treated mature DCs will induce the death of neutrophils.
