On the cover: Cross-linking of the IgA receptor FcαRI by IgA–immune complexes induces migration of neutrophils and eosinophils. An IgA-coated Sepharose bead, which was added to a monolayer of granulocytes, is shown. After a 20 min incubation period, the bead is covered with both neutrophils (green) and eosinophils (red). van der Steen, L. P., J. E. Bakema, A. Sesarman, F. Florea, C. W. Tuk, G. Kirtschig, J. J.
