20110135736	Compositions and Methods for Producing Vascular Occlusion using a Solid-phase Platelet Binding Agent - The present invention relates generally to methods and compositions for targeting and delivering solid-phase platelet-dependent vascular occlusion agents. In particular, particles or coils or stents coated with platelet binding agents are directed to target vasculature, such as the vasculature of solid tumor masses or AV-malformations or aneurysms or endoleaks; the solid-phase agent then binds and activates platelets, which in turn bind and activate other platelets. This process results in the rapid formation of a platelet-mediated thrombus about the solid-phase agent causing vessel occlusion.	06-09-2011

20110189180	ANTIGENIC COMPOSITIONS AND USE OF SAME IN THE TARGETED DELIVERY OF NUCLEIC ACIDS - Methods and compositions are provided for delivery of therapeutic nucleic acids to a target cell. A chimeric antigen is provided to encapsulate, bind, or otherwise carry a nucleic acid molecule to a target cell where the chimeric antigen and nucleic acid are internalized by receptor-mediated endocytosis. The chimeric antigen has a nucleic acid interaction domain, a target binding domain, and an immune response domain that may include a target antigen. Targeting is generally provided by the specificity of the target binding domain for a particular target cell receptor, but may also be provided by inclusion of a targeting antigen within the immune response domain. The combined delivery of chimeric antigen and nucleic acid, which may be a siRNA, may be synergistic in certain applications, for example in breaking host tolerance to a virus or in providing immunostimulation.	08-04-2011

20090202560	Method for diagnosing efficacy of xenotypic antibody therapy - The invention concerns methods and compositions for intiating and/or enhancing an immune response by contacting a binding reagent with a soluble antigen, wherein the binding reagent-antigen pair generates an immune response to the antigen.	08-13-2009
20090220493	Reagents and methods for inducing an immune response to prostate specific antigen - The invention is an apparatus and method for the treatment of prostate cancer, and involves administering an antibody that specifically binds with prostate antigen.	09-03-2009
20090238822	Chimeric Hepatitis C Virus Antigens For Eliciting an Immune Response - Disclosed herein are chimeric antigens, comprising an hepatitis C virus (HCV) antigen and a Fc fragment of an immunoglobulin for eliciting an immune response against said antigen. The immune response is enhanced by presenting the host immune system with an immune response domain (HCV antigen from HCV core, envelope, or non-structural protein fragments) and a target binding domain (an Fc fragment). By virtue of the target binding domain, antigen presenting cells internalize and process the chimeric antigens for antigen presentation, thereby eliciting both a humoral and cellular immune response.	09-24-2009
