Actions of dendrimer ABP on cytokine production by MoDC. TNFα, IL-6, IL-23, IL-12 and IL-10 were measured in the culture supernatant of activated MoDC from 11 donors. Data are presented as box plots. Activation was performed, as indicated, in the presence or in the absence of dendrimer ABP. *P <0.05; **P <0.005. ABP, aza-bis-phosphonate; IL, interleukin; MoDC, monocyte derived dendritic cells; TNF, tumor necrosis factor.
