Tumor and viral antigens elicit a potent immune response by heat shock protein-dependent uptake of antigenic peptide with subsequent presentation by MHC I. Receptors on antigen-presenting cells that specifically bind and internalize a heat shock protein-peptide complex have not yet been identified. Here, we show that cells expressing CD40, a cell surface(More)
The transforming growth factor beta (TGFbeta) superfamily includes bone morphogenetic proteins, activins and TGF-betasensu stricto (s.s.). These ligands have been shown to play a key role in numerous biological processes including early embryonic development and immune regulation. They transduce their signal through a hetromeric complex of type I and type(More)
The transforming growth factor b (TGFb) superfamily includes bone morphogenetic proteins, activins and TGF-b sensu stricto (s.s.). These ligands have been shown to play a key role in numerous biological processes including early embryonic development and immune regulation. They transduce their signal through a hetromeric complex of type I and type II(More)
