T cell–B cell contacts in mice treated with anti–DEC205-CS. Red indicates OT-II T cells, green indicates B1-8^hi B cells, and cyan indicates B-18^hiDEC205 ^{−/ −} B cells. Long-lasting (>10 min) motile conjugates are marked by circles colored according to B cell genotype. This video is shown at 7 frames/s
