Immunology What's in a Vaccine?

Stephen Simpson

Science, AAAS, Washington, DC 20005, USA

After vaccination, the efficiency with which protective antibodies are produced often depends on the presence of an adjuvant, a substance that promotes activation of antibody-producing B cells. It has been anticipated that Toll-like receptors (TLRs) might be major players in mediating the effects of adjuvants. However, Gavin et al. now find that the known TLR pathways do not modulate B cell responses, and so adjuvants containing TLR ligands must depend on other properties. Such a revision to thinking about the effects of TLR on B cell responses will likely refocus current thinking about vaccine development.
