B7-Dc, a New Dendritic Cell Molecule with Potent Costimulatory Properties for T Cells
Dendritic cells (DCs), unique antigen-presenting cells (APCs) with potent T cell stimulatory capacity, direct the activation and differentiation of T cells by providing costimulatory signals. As such, they are critical regulators of both natural and vaccine-induced immune responses. A new B7 family member, B7-DC, whose expression is highly restricted to DCs, was identified among a library of ge...
متن کاملCross-linking the B7 family molecule B7-DC directly activates immune functions of dendritic cells
B7-DC molecules are known to function as ligands on antigen-presenting cells (APCs), enhancing T cell activation. In this study, cross-linking B7-DC with the monoclonal antibody sHIgM12 directly potentiates dendritic cell (DC) function by enhancing DC presentation of major histocompatibility complex-peptide complexes, promoting DC survival; and increasing secretion of interleukin (IL)-12p70, a ...
متن کاملFunctional expression of the costimulatory molecule, B7/BB1, on murine dendritic cell populations
Whereas dendritic cells (DC) are known to be potent activators of T cells both in vitro and in vivo, the critical costimulatory molecules expressed on DC are not well characterized. Using immunocytochemical and molecular techniques we find that splenic DC express B7/BB1, the counter-receptor for CD28. Moreover, expression of B7/BB1 is upregulated on epidermal Langerhans cells (LC) during their ...
متن کاملOx-40 ligand: a potent costimulatory molecule for sustaining primary CD4 T cell responses.
Ox-40 and Ox-40 ligand (Ox-40L) are thought to be involved in T cell-APC interactions. However, their exact role in T cell responses is undefined. Using fibroblast transfectants expressing Ox-40L and/or B7-1, and CD4 cells from TCR transgenic mice, we investigated the effect of Ox-40 signaling on primary responses to the Ag pigeon cytochrome c. Ox-40 expression on naive CD4 cells peaked 2 to 3 ...
متن کاملAnterior pituitary progenitor cells express costimulatory molecule 4Ig-B7-H3.
Stem/Progenitor cells in the postnatal pituitary gland are embedded in a marginal cell layer around Rathke's pouch. However, the nature and behavior of anterior pituitary progenitor cells remain unclear. We established bovine anterior pituitary progenitor cell line (BAPC)-1 from the anterior pituitary gland, which expressed stem/progenitor cell-related genes and several inflammatory cytokines. ...
