CD11b/CD18 mimics the effect of C3bi on DC cytokines.

Quantitation of cytokines released by immunomagnetic bead-sorted BM DCs after interaction with polysterene beads coated with anti-CD11b (M1/70), anti-CD18 (GAME-46), anti-CD11a (LFA-1), or irrelevant IgG. Basal levels of TGF-β1 in the culture medium were deducted. Results are illustrated as the means ± SDs of 3 different experiments; *P ≤ .05 and **P ≤ .01.
