Combinations of TLR Ligands: A Promising Approach in Cancer Immunotherapy
Figure 3
Flow cytometric phenotyping of TLR ligand stimulated PBLs. PBLs were either incubated with single TLR ligands (0.01 μM; (a) and (b) upper panel) or in the presence of TLR ligand combinations (0.01 μM; (a) and (b) lower panel) for 72 h. (a) Activation of PBLs following TLR stimulation as given by positive staining for CD25 and CD69. (b) CD16+CD56+ NK cells were the main responding cell population. Data of untreated control PBLs were set as 1 and all data were given as X-fold increase. Values are presented as mean + SD; versus control; t-test.
