In addition to their essential role in adaptive immunity, dendritic cells (DCs) participate in innate immunity. In the context of measles virus (MV) or cytomegalovirus infections, they develop cytotoxic functions that may contribute in vivo to the elimination of virus-infected cells, but that also kill infected and noninfected T lymphocytes. Because the(More)
Dendritic cells (DCs) were recently found to be innate immunity effectors against tumoral cells and viruses. (i) In response to most viruses, including HIV, plasmacytoid DCs are responsible for most of the type I IFN secretion, which is strongly anti-viral and induces TH1 type responses. Myeloid DCs secrete IL-12, which is also important for TH1-type and(More)
B lymphocytes express at their surface the CD40 antigen which belongs to the NGF receptor superfamily. The crosslinking of the CD40 antigen using a mouse fibroblastic cell line expressing the human Fc receptor (Fc gamma RII/CDw32) and anti-CD40 monoclonal antibody induces resting B lymphocytes to enter a state of sustained proliferation. Addition of IL-4 or(More)
