The ability of interleukin (IL)-12 to prevent tumors when administered to individuals with a genetic risk of cancer was studied in two lines of transgenic mice expressing rat HER-2/neu oncogene in the mammary gland. Female BALB/c (H-2(d)) mice carrying the activated HER-2/ neu oncogene show no morphological abnormalities of the mammary gland until 3 wk of(More)
SumlTlary Interleukin (IL) 12 is a proinflammatory cytokine produced by phagocytic cells, B cells, and other antigen-presenting ceils that modulates adaptive immune responses by favoring the generation ofT helper type 1 cells. IL-12 mediates some of its physiological activities by acting as a potent inducer of interferon (IFN) y production by T and natural(More)
The B7/CD28 costimulatory pathway plays a critical role in T cell activation including Th1/Th2 differentiation. However, little is known about whether CD28 costimulation favors polarization of either Th1 and Th2 or both. Here, we show a critical role of the natural ligands for CD28 molecules (B7.2-Ig or B7.1-Ig fusion proteins), particularly in the(More)

The gamma-glutamyl cycle is thought to play a significant role in the transport of amino acids between the blood and the cerebrospinal fluid. In the present study we investigated the expression of 5-oxo-L-prolinase, an enzyme of this pathway, in mouse brain and kidney by in situ hybridization using digoxygenin-labeled RNA probes. Expression of 5-OPase mRNA(More)
