FIG 1.

Expression of costimulatory molecules CD40 and CD86 on DCs in response to full-length GroEL2 and GroEL2(cl). We stimulated C57BL/6 BMDCs with recombinant GroEL2 or GroEL2(cl) for 24 h and analyzed the cell surface expression of CD40 and CD86. Representative histograms and mean fluorescence intensity values for the CD11c⁺ DC subpopulation are shown. Isotype and Pam₃CSK₄ controls are shown as gray and green outlines, respectively. Data are shown as means ± SD of results of one representative experiment from three independent experiments.
