Critical role of ITIM-bearing FcgammaR on DCs in the capture and presentation of native antigen to B cells

Immunity. 2005 Nov;23(5):463-4. doi: 10.1016/j.immuni.2005.10.005.

Abstract

The contribution of dendritic cells (DCs) to antibody responses through antigen-unspecific B cell costimulation is well documented. now demonstrate that the ITIM-bearing FcgammaRIIB allows DCs to recycle internalized native antigen (Ag) for presentation to B cells, a process that might be critical for the initiation of humoral responses.
