Actions of dendrimer ABP on cytokine production by monocytes. TNFα, IL-1β, IL-6, IL-23, IL-12 and IL-10 were measured in the culture supernatant of activated Mo from 12 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 = 0.0005. ABP, aza-bis-phosphonate; IL, interleukin; Mo, monocytes; TNF, tumor necrosis factor.
