Abstract: Disclosed are short DNA aptamers that selectively recognize CD200R1, a protein expressed on the surface of myeloid and lymphoid cells that delivers immune inhibitory signals to modulate inflammation when engaged with its ligand, CD200. Also disclosed is the use of said aptamers as therapeutic agents, for the purpose of decreasing inflammatory response; treatment of spinal cord injury; treatment of an immune related disease such as arthritis, asthma, allergy, infection; as a course of treatment during or after transplantation; or for treatment of an autoimmune disorder such as systemic lupus erythematosus, Parkinson's Disease, or multiple sclerosis.

Abstract: Methods and compositions for modulating bone development are described.

Abstract: The present invention relates to a pharmaceutical composition representing a novel immunomodulating principle comprising bacterial endotoxin, fetal hemoglobin or more particularly a heme-free derivative or the ?-chain thereof, and optionally, components which are present in the fetal liver in addition to HbF. The composition is delivered to humans in a pharmaceutically acceptable carrier and/or diluent. In accordance with the present invention it was surprisingly found that endotoxin and fetal hemoglobin partial structures display a pronounced synergistic biomedical activity. The biomedical effect of fetal hemoglobin and its partial structures is surprisingly not based on a classical hemoglobin function as an oxygen transporter but related to a modulation of endotoxin-mediated bioactivity. This biomedical activity is surprisingly also observed after oral application of the composition.

Abstract: Methods and compositions for regulating immunity are disclosed. For enhancing an immune response, agents that inhibit OX-2 are administered. Such methods are useful in treating cancer. For suppressing an immune response, an OX-2 protein or a nucleic acid encoding an OX-2 protein is administered. Such methods are useful in preventing graft rejection, fetal loss, autoimmune disease, allergies and in inducing tumor cell growth.

Abstract: Methods and compositions for inducing immune suppression are disclosed. The methods involve administering an effective amount of a CD200 protein or a nucleic acid encoding a CD200 protein. The methods are useful in preventing graft rejection, fetal loss, autoimmune disease, and allergies. Methods and compositions for preventing immune suppression are also disclosed. The methods involve administering an effective amount of an agent that inhibits CD200. Such methods are useful in treating cancer.
