The 4-1BB receptor (CDw137), a member of the tumor necrosis factor receptor superfamily, has been shown to costimulate the activation of T cells. Here we show that anti-mouse 4-1BB monoclonal antibodies (mAbs) inhibit thymus-dependent antibody production by B cells. Injection of anti-4-1BB mAbs into mice being immunized with cellular or soluble protein(More)
The monoclonal antibody (mAb) J393 induces apoptosis in Jurkat T-cells. NH2-terminal amino acid sequence analysis identified the 140-kDa surface antigen for mAb J393 as CD43/leukosialin, the major sialoglycoprotein of leukocytes. While Jurkat cells co-expressed two discrete cell-surface isoforms of CD43, recognized by mAb J393 and mAb G10-2, respectively,(More)
Cultured human umbilical vein endothelial cells (HUVECs) are a valuable model for investigation of endothelial functions, but they enter senescence at low passage. Transfection of early passage HUVECs with the early genes of SV40 greatly extends the replicative potential of these cells, but eventually results in marked changes in growth, morphology, and(More)
