Cutting edge: dendritic cell actin cytoskeletal polarization during immunological synapse formation is highly antigen-dependent.


Dendritic cells (DC) actively rearrange their actin cytoskeleton to participate in formation of the immunological synapse (IS). In this study, we evaluated the requirements for DC participation in the IS. DC rearrange their actin cytoskeleton toward naive CD4(+) T cells only in the presence of specific MHC-peptide complexes. In contrast, naive CD4(+) T… (More)
