Effect of NPs on ex vivo differentiation of naïve CD4+ T cells. Absolute number of CD4+ T cells after 7 days of co-cultivation with either OVA-imDCs (a) or OVA-mDCs (b). CD4+ T cell differentiation after 7 days of co-cultivation with either OVA-imDCs (c) or OVA-mDCs (d). Naïve unstimulated CD4+ T cells represent basal activation. CD4+ T cells pulsed with PHA represent a positive proliferation control
