Our laboratory has previously isolated several tumor cell populations from a single, spontaneously arising mammary tumor of a BALB/cfC3H mouse and established them in tissue culture as independent sublines. These subpopulations differ according to many criteria including growth parameters and expression of tumor-associated antigens. We have tested the(More)
Studies in nonhuman primates have demonstrated that elevation of the cytotoxic lymphocyte (CL) genes granzyme B, perforin, and Fas ligand in peripheral blood precedes islet allograft rejection. The purpose of this study was to determine whether this approach has utility for prediction of human islet allograft loss. We studied 13 patients who had long-term(More)
The purpose of this study was to compare mRNA levels of the cytotoxic lymphocyte (CL) gene products: granzyme B (GB), perforin (P), and fas ligand (FasL) in patients with long-term type 1 diabetes and healthy controls. The objective was to utilize this information to follow patients as they undergo islet cell transplantation at our center and to determine(More)
Cancer chemotherapeutic agents modify the human immune system in diverse ways including both immunosuppression and immunostimulation. We evaluated the effects of mitomycin-C on rat Kupffer cell phagocytosis, C3b receptor binding, and lysosomal enzyme activity. Kupffer cell cultures were greater than 95% pure. Phagocytosis of IgG-coated sheep red blood cells(More)
