Abstract: The present invention relates to methods and materials for more effectively treating patients with interferon. It is based on the discovery that clinical response to interferon (IFN) therapy is mediated in part by inhibition of activation of MDSC and such inhibition can be observed after a test dose of interferon; a significant decrease of reactive oxygen species (ROS) production by MDSC (as a measure of their activation) after IFN therapy is predictive of overall response to immunotherapy in cancer patients.

Abstract: An improved apparatus and method for dispersion of a labeling conjugate in a diagnostic assay, the result being a one-step assay. By eliminating a conjugate pad as in conventional lateral diagnostic devices, and forming a frazil ice pellicle (FIP), rehydration and flow are improved resulting in better reproducibility, improved sensitivity, and reduced costs of individual assay devices. The formation of a frazil ice film formed on a super cooled surface of a sample receiving means simplifies assay assembly. Lyophilization of the FIP improves the release of a sample/analyte/label matrix into a macro channel as in a direct flow assay, while at the same time allowing reagents to mix and flow, thereby optimizing the assay performance. The reagents of the conjugate and the formation of the FIP stabilize the conjugate proteins and provide extended shelf life to the diagnostic assay device.

Abstract: The site-specific expression of selectins on endothelial cells of blood vessels during angiogenesis provides an opportunity to target anti-cancer drugs to the vascular endothelium to extend the range of the therapeutic effect. This invention describes an innovative drug targeting strategy for the selective delivery of the anticancer drugs to endothelial cells by means of polymer-drug conjugates modified with a carbohydrate ligand for the vascular selectins. A model chemotherapeutic drug, doxorubicin, and the E-selectin ligand, sLex, are attached to a biocompatible polymer (HPMA). The selective binding, cellular uptake, intracellular fate, and cell cytotoxicity of the polymer-bound drug are investigated in human endothelial cells.
