ABSTRACT
<p><b>OBJECTIVE</b>To investigate the inducing effect of 'modified' cytokine cocktail on the dendritic cell maturation and migration capability.</p><p><b>METHODS</b>PBMNC were isolated from human peripheral blood stem cell (PBSC) by using density gradient centrifugation, the immature DC (imDC) were induced by using GM-CSF and IL-4 in vitro. Total A549 RNA was transfected into imDC by using electroporation, which was stimulated to matuation by the "gold standard" cytokine cocktail and "modified" cytokine cocktail, respectively. The expression of DC surface markers (CD11c, HLA-DR, CD80, CD83 and CD86) and chemokine receptor (CCR5, CCR7 and CXCR4) were detected by flow cytometry; the mRNA expression levels of DC chemokine receptor (CCR2, CCR5, CCR7, CXCR3 and CXCR4) and chemokine (CCL2, CCL3, CCL5, CCL19, CCL21, CXCL10 and CXCL12) were detected by RT-PCR.</p><p><b>RESULTS</b>As compared with "gold standard cytokine cocktail", the "modified" cytokine cocktail-induced DC expressed higher levels of surface markers (CD11c, HLA-DR, CD80, CD83 and CD86), chemokine receptors (CXCR4) and chemokine (CCL2, CCL3, CCL5, CCL19, CCL21, CXCL10 and CXCL12).</p><p><b>CONCLUSION</b>The "modified" cytokine cocktail can more effectively induce the DC maturation, enhace the migratory capability of DC and more generate the immunostimulatory DC, when compared with the "gold standard" cytokine cocktail effect.</p>
