摘要:
The invention is directed to novel compositions and methods utilizing virion derived protein nanoparticles for delivery of medical imaging agents and therapeutic agents for the diagnosis and treatment of malignant and systemic diseases. The nanoparticles of the present invention are designed to deliver radioactive isotopes suitable for imaging a tumor and its metastases. Additionally, the nanoparticles may deliver a radioisotope that is suitable for treating a tumor and its metastases by alpha, beta or gamma radiation. Alternatively, the virion derived nanoparticles may deliver a treatment agent for cancer or a combination of a radioisotope and a cancer treatment agent. Additionally the virion derived nanoparticle may include delivery of a drug that enhances the immune system's recognition of the tumor.

This invention relates to a transdermal delivery system for treating skin related diseases employing protein nanoparticles to deliver drugs to the keratinocytes and basal membrane cells for the treatment of non-melanoma skin cancer. The current invention presents an effective method for delivering small molecule nucleic acids to the epidermal cells.
摘要:
Methods for delivering naked DNA vaccines to enhance immune responses, by improving transfection efficiency without safety concerns associated with live viral vectors, are described. A method may comprise administering to a mammalian subject an effective amount of a papillomavirus pseudovirion, wherein the papillomavirus pseudovirion comprises at least one papillomavirus capsid protein encapsidating a naked DNA vaccine, wherein the naked DNA vaccine comprises a first nucleic acid encoding at least one antigen, thereby enhancing the antigen specific immune response relative to administration of the naked DNA vaccine.
摘要:
The present invention relates to biologically useful material in the form of a pseudocapsid formed from papovavirus major capsid antigen and excluding minor capsid antigens, which pseudocapsid incorporates exogenous material. The invention also relates to a method of using the pseudocapsids as vectors for exogenous material transfer, especially gene transfer in the therapy of genetic disorders, of other uses such as antibody or drug targeting.
摘要:
A non-human papilloma pseudovirus or virus like particle has at least one papilloma capsid protein codon-optimized for expression in eukaryotic cells or cell lines. A pharmaceutical composition includes the non-human papilloma pseudovirus or virus like particle, and a diagnostic agent, an imaging agent, and a therapeutic agent. A non-human papilloma pseudovirus or virus like particle can be used as a medicament. A method for producing a non-human papilloma pseudovirus or virus like particle involves codon-optimizing of capsid proteins of non-human papillomaviruses for expression in eukaryotic cells, synthesizing of the sequences and cloning of the synthesized sequences into expression vectors, and producing non-human papilloma pseudovirus or virus like particles. ι-carrageenan can be used as transduction enhancer for non-human papilloma pseudovirus or virus like particles in vitro.
