Figure 4From: CTLA4 is expressed on mature dendritic cells derived from human monocytes and influences their maturation and antigen presentationThe culture of immature DCs in wells coated with anti-CTLA4 antibody did not affect their endocytic activity. Endocytosis was evaluated as the uptake of FITC-DX at the indicated times, which was measured by FACS. The data for one experiment are shown, and are representative of three independent experiments.Back to article page
