Patents by Inventor Hans Keirstead

Hans Keirstead has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20070231898
    Abstract: This invention provides populations of neural cells bearing markers of glial cells, such as oligodendrocytes and their precursors: The populations are generated by differentiating pluripotent stem cells such as human embryonic stem cells under conditions that promote enrichment of cells with the desired phenotype or functional capability. Various combinations of differentiation factors and mitogens can be used to produce cell populations bearing markers of oligodendrocyte precursor cells. Upon further differentiation form complex processes characteristic of mature oligodendrocytes. The cells are capable of forming myelin sheaths, and can be used therapeutically improve function of the central nervous system.

  • Publication number: 20050191293
    Abstract: The present invention provides isolated monoclonal antibodies, particularly human antibodies, that bind to IP-10 with high affinity, inhibit the binding of IP-10 to its receptor, inhibit IP-10-induced calcium flux and inhibit IP-10-induced cell migration. Nucleic acid molecules encoding the antibodies of the invention, expression vectors, host cells and methods for expressing the antibodies of the invention are also provided. Immunoconjugates, bispecific molecules and pharmaceutical compositions comprising the antibodies of the invention are also provided. The invention also provides methods for inhibiting IP-10 activity using the antibodies of the invention, including methods for treating various inflammatory and autoimmune diseases.

  • Publication number: 20050008641
    Abstract: Novel compositions are described comprising the combined administration of serum complement proteins with complement-fixing antibodies. The antibodies specifically bind to one or more epitopes of myelin, and complement proteins. These compositions are useful for promoting regrowth, repair, and regeneration of neurons in the CNS of a mammalian subject. The compositions and method can be used following immediate or chronic injury.
