Uptake of ssCpG and tetraCpG in untreated, mock-transfected, or MSR1-transfected HEK-Blue hTLR9 cells. Each Alexa Fluor 488-labeled DNA sample was added to cells at a concentration of 2 μg/mL. The results are expressed as means + SEM of three independent experiments. *P < 0.05 compared with the mock-transfected group.
