Dendritic cell-derived growth factor

摘要

The present invention relates to a novel DCDGF protein which is a member of a novel family of growth factors of which the prototype is called Insect-Derived Growth Factor (IDGF). In particular, isolated nucleic acid molecules are provided encoding the human DCDGF protein. DCDGF polypeptides are also provided as are vectors, host cells and recombinant methods for producing the same. The invention further relates to screening methods for identifying agonists and antagonists of DCDGF activity. Also provided are diagnostic methods for diagnosing DiGeorge Syndrome and, particularly, immune system-related disorders. and therapeutic methods for treating immune system-related disorders.
