The CD154/CD40 interaction required for retrovirus-induced murine immunodeficiency syndrome is not mediated by upregulation of the CD80/CD86 costimulatory molecules.

چکیده
C57BL/6 (B6) mice infected with LP-BM5 retroviruses develop disease, including an immunodeficiency similar to AIDS. This disease, murine AIDS (MAIDS), is inhibited by in vivo anti-CD154 monoclonal antibody treatment. The similar levels of insusceptibility of CD40(-/-) and CD154(-/-) B6 mice indicate that CD154/CD40 molecular interactions are required for MAIDS. CD4(+) T and B cells, respectively, provide the CD154 and CD40 expression needed for MAIDS induction. Here, the required CD154/CD40 interaction is shown to be independent of CD80 and CD86 expression: CD80/CD86(-/-) B6 mice develop MAIDS after LP-BM5 infection.

CD40-associated TRAF 6 signaling is required for disease induction in a retrovirus-induced murine immunodeficiency.
LP-BM5 retrovirus-infected C57BL/6 mice develop splenomegaly, lymphadenopathy, hypergammaglobulinemia, and immunodeficiency; thus, this disease has been named mouse AIDS. In this syndrome, CD154/CD40 interactions are required for but do not mediate disease by upregulation of CD80 or CD86. We report here that there is nonetheless a necessity for CD40 signaling competence, specifically an intact ...
متن کاملCD80 and CD86, but not CD154, augment DNA vaccine-induced protection in experimental bovine tuberculosis.
DNA vaccination is known to elicit robust cellular and humoral responses to encoded antigen. The co-administration of costimulatory molecules CD80 (B7-1), CD86 (B7-2) and CD154 (CD40L) has been shown to enhance immune responses in several murine models. The role of specific costimulatory molecules in non-rodent species remains incompletely characterized. In these studies, we demonstrate that th...
متن کاملDifferential regulation of Th1 and Th2 functions of NKT cells by CD28 and CD40 costimulatory pathways.
Valpha14 NKT cells produce large amounts of IFN-gamma and IL-4 upon recognition of their specific ligand alpha-galactosylceramide (alpha-GalCer) by their invariant TCR. We show here that NKT cells constitutively express CD28, and that blockade of CD28-CD80/CD86 interactions by anti-CD80 and anti-CD86 mAbs inhibits the alpha-GalCer-induced IFN-gamma and IL-4 production by splenic Valpha14 NKT ce...
متن کاملNK cell triggering by the human costimulatory molecules CD80 and CD86.
NK cell-mediated effector functions are regulated by a delicate balance between positive and negative signals. Receptors transmitting negative signals upon engagement with target cell MHC class I molecules have been characterized in detail in recent years. In contrast, less information is available about receptor-ligand interactions involved in the transmission of positive or "triggering" signa...
متن کاملEncoding CD40 Ligand Intratumoral Injection of Recombinant Fowlpox Virus Therapeutic Vaccination against Murine Lymphoma by Updated Version
The interaction between CD40 ligand (CD40L, CD154) and its receptor CD40 on antigen-presenting cells is essential for the initiation of cell-mediated and humoral immune responses. Malignant B cells also express CD40 and respond to CD40L by enhancing expression of costimulatory molecules. In this study, we investigated the therapeutic antitumor effect of intratumoral administration of recombinan...
