ABSTRACT
AIM:
To study the effect of oligonucleotides containing unmethylated CpG motif (CpG ODN) on mouse bone marrow-derived dendritic cells (BMDCs) in anti-HcaF cytotoxicity.METHODS:
BMDCs were stimulated by CpG ODN in combination with tumor antigen (TAg). The expression of CD80 on BMDC surface was analyzed by FCAS. Level of IL-12 (p70) in supernatants of BMDC culture was detected by ELISA. The proliferation of T cells was examined by MTT assay. Cytotoxicity of CTL induced by CpG ODN combining with TAg was detected by MTT assay.RESULTS:
CpG ODN combining or not combining with TAg up-regulated the expression of CD80 on BMDC surface and stimulated BMDCs to produce a high level of IL-12. CpG ODN-activated BMDC promoted the proliferation of T cells. CTL induced by CpG ODN in combination with TAg appeared strong specific cytotoxicity on Hca-F cells.CONCLUSION:
CpG ODN may effectively induce the functional maturation of mouse BMDC in vitro. CpG ODN in combination with TAg can enhance the anti-HcaF cytotoxicity of CTL. [
