Title: Keiko Ikeda: Innovator in Viral Polyhedra Complexes
Introduction
Keiko Ikeda is a prominent inventor based in Kyoto, Japan. She has made significant contributions to the field of biotechnology, particularly in the study of viral polyhedra complexes. With a total of 3 patents, her work focuses on understanding and utilizing the unique properties of these viral structures.
Latest Patents
One of her latest patents involves the development of viral polyhedra complexes and methods of use. Cypoviruses and baculoviruses are notoriously difficult to eradicate due to their virus particles being embedded in micron-sized protein crystals known as polyhedra. These polyhedra exhibit remarkable stability, allowing the viruses to remain infectious for years in soil. Ikeda's research describes the crystal structure of both recombinant and infectious silkworm cypovirus polyhedra, determined using 5-12 micron crystals purified from insect cells. This work reveals that polyhedra are composed of trimers of the viral polyhedrin protein and contain nucleotides. The unique folding of polyhedrin allows it to assemble into 3-D cubic crystals, which are extensively cross-linked and shield the virus particles from environmental damage. This structure suggests potential applications for developing robust nanoparticles in biotechnological fields such as cell culture systems, microarrays, and biopesticides.
Another significant patent focuses on a cytoplasmic polyhedrosis virus protein complex comprising a polyhedral protein encapsulating an insect virus and a target protein. This invention aims to provide an efficient production process for the protein complex without compromising its functionality. The polyhedral protein enhances the stability and preservation properties of the target protein, making it suitable for use in biosensors and immobilized enzymes.
