The compartmentalized production of superoxide (*O(2)(-)) by endosomal NADPH oxidase is important in the redox-dependent activation of NF-kappaB following interleukin 1beta (IL-1beta) stimulation. It remains unclear how *O(2)(-) produced within endosomes facilitates redox-dependent signaling events in the cytoplasm. We evaluated *O(2)(-) movement out of(More)
The selective toxicity of anticancer drugs can be improved with the use of antibody-targeted liposomes. We hypothesize that liposomes targeted via antibodies against two or more receptor populations will increase the apparent receptor density on the target cells, resulting in improved therapeutic affects. A fluorescent assay was developed, using the(More)
Some formulations of liposomal doxorubicin with intermediate rates of drug release have shown increased levels of toxicity in mice. Because antibody-mediated targeting of liposomal drugs influences the pharmacokinetics, mechanism of uptake, and selectivity of the associated drugs, we hypothesized that anti-CD19-mediated targeting of liposomal doxorubicin(More)
Patients with advanced or metastatic melanoma have a very poor prognosis, due to the resistance of melanoma cells to conventional chemotherapy. We previously reported that coated cationic liposomes targeted with a monoclonal antibody against the disialoganglioside GD(2) and containing c-myc antisense oligodeoxynucleotides (alpha GD(2)-CCL[c-myc-as]) induced(More)
