  • Patent number: 7378098
    Abstract: In accordance with various aspects of the invention, CXCR4 agonists, including SDF-1 polypeptides and SDF-1 polypeptide homologues, may be used in reducing the rate of hematopoietic cell multiplication. Methods of the invention may comprise administration of an effective amount of an CXCR4 agonist to cells selected from the group consisting of hematopoietic stem cells and hematopoietic progenitor cells. Cells may be treated in vitro or in vivo in a patient. A therapeutically effective amount of the CXCR4 agonist may be administered to a patient in need of such treatment. Patients in need of such treatments may include, for example patients requiring bone marrow or peripheral blood stem cell transplantation.

  • Publication number: 20070275892
    Abstract: The present disclosure generally teaches compositions comprising SDF-1 mimetics and methods of using them to modulate an activity of a cell having an SDF-1 receptor by binding the SDF-1 receptor to an SDF-1 mimetic. The cell can be a hematopoietic cell, for example, and can be selected from a group consisting of hematopoietic stem cells, hematopoietic progenitor cells, primitive granulocytes, primitive erythroid cells, leukocytes, and neutrophils. In some embodiments, the activity can include the rate of multiplication of the cell or, where the cell is a quiescent cell, the binding can repress the activation of the quiescent cell. Other embodiments of the present invention are taught herein.

  • Publication number: 20070160574
    Abstract: The present invention generally relates to the design, preparation, derivation, and use of mimetics of CXC chemokines (CXCL1-CXCL17) in the prevention, treatment, and ameliorization of a wide variety of diseases and disorders. Generally speaking, this invention is directed to the design, synthesis, and use of chemokine analogs which bind to CXC chemokine receptors CXCR1-CXCR7, such that the analogs can be designed to affect the activity of the receptor, either as an agonist or an antagonist. The analogs can be useful for treating a wide variety of diseases and disorders, and can also serve as an adjunct to the treatment of a variety of diseases and disorders.

  • Publication number: 20070116669
    Abstract: This invention is directed to peptide analogs of interferon-inducible protein-10 (IP-10 or CXCL10) chemokine that bind to the CXCR3 receptor or any other receptor in which IP-10 analogs can bind to as a ligand, such that the analogs can be designed to serve as agonists or antagonists of IP-10 chemokine. The analogs can be used to prevent, treat, or ameliorate the symptoms of, a disease.
