摘要:
It is a main object of the present invention to provide a drug delivery system in which drugs can be changed or which can be recharged with drugs, which continuously delivers drugs at effective concentrations to local lesional sites in a body and allows the use of drugs for which it has thus far been difficult to achieve effective local concentrations for a variety of reasons and drugs which have been difficult to use due to adverse effects on tissues that are not sites of action. The present invention provides a drug delivery system comprising an indwelling medical device on which a biocompatible material having target molecules on its surface has been coated, and target-recognizing nanocarriers (e.g., bio-nanocapsules, liposomes, liposome preparations, and nanoparticles) in which drugs are encapsulated and which have target-recognizing molecules capable of specifically binding to the target molecules.

摘要:
The present invention provides a method for purifying a heat-resistant bio-nanocapsule composed mainly of a protein produced by using a eukaryotic cell. The method comprises heat-treating a lysate of the eukaryotic cell to remove contaminant proteins, and then subjecting the resulting product to chromatography.

The invention generally relates to a bone growth factor, and more particularly to compositions including NELL1, articles of manufacture including NELL1 and methods of using NELL1 to induce bone formation. This invention also provides methods for the expression and purification of NELL1 and NELL2 peptides.
摘要:
The invention provides hollow nanoparticles of a protein with the ability to recognize specific cells such as the hepatocytes and to form particles (for example, hepatitis B virus surface-antigen protein), wherein the protein has a cysteine residue substituted to a different amino acid. The hollow nanoparticles have a stable particle structure and can be used to efficiently transfer substances to specific target cells or tissues. The invention also provides a drug using the hollow nanoparticles.

摘要:
The subject invention provides a disease-treating drug that uses hollow protein nanoparticles to specifically act on a target cell or tissue. The present invention allows a protein drug to be effectively capsulated in the particles. The invention also provides a therapeutic method using such a drug. The drug according to the present invention is capable of recognizing a specific cell, such as hepatocytes, and manufactured by fusing a disease-treating substance for a target cell (for example, interferon, hepatocyte growth factor etc.) with hollow nanoparticles of a particle-forming protein (for example, hepatitis B virus surface-antigen protein).

Provided herein is a pharmaceutical composition for treating, preventing or ameliorating a bone or cartilage condition and methods of making and using the same.
摘要:
The invention provides a therapeutic drug that uses hollow protein nanoparticles displaying an antibody against a specific cell or specific tissue. The effectiveness of the drug has been proved by animal testing. The invention also provides a therapeutic method using such a drug. In a drug according to the present invention, a substance to be transferred into a cell for treating a disease (for example, a cancer treating gene such as a thymidine kinase gene derived from simple herpes virus) is encapsulated in hollow nanoparticles of a particle-forming protein (for example, hepatitis B virus surface-antigen protein that has been modified to lack its infectivity to hepatocytes and display an antibody). The particle surface of the drug displays an antibody, such as a cancer specific antibody, that recognizes an antigen molecule displayed on the surface of a specific cancer cell.
