20090117155 | TREATMENT OF HIV-1 BY MODULATION OF VPR ACTIVATION OF THE M-CSF PROMOTER - Macrophage colony-stimulating factor (M-CSF) is important for human immunodeficiency virus-type 1 (HIV-1) infection, replication and survival of infected cells. The mechanism(s) by which HIV-1 infection increases M-CSF production are, however, poorly understood. Here, we report that HIV-1 Vpr enhances M-CSF promoter activity and production in primary human monocytes and macrophages. Vpr activates M-CSF transcription through four C/EBP beta binding sites present within the M-CSF promoter, possibly through increased phosphorylation of C/EBP beta. RU486 (mifepristone) blocked Vpr-mediated up-regulation of M-CSF, suggesting that Vpr activates M-CSF promoter activity via the glucocorticoid pathway. The invention provides new avenues for therapeutic interventions in HIV-1 infection and other diseases involving M-CSF dysregulation (including malignancy, osteoporosis, autoimmune disorders, arthritis, and obesity) using glucocorticoid antagonists and modulators of C/EBP beta activity. | 05-07-2009 |

20090220542 | VACCINE COMPRISED SPECIFICALLY OF PROTEIN SUBUNITS OF HUMAN IMMUNODEFICIENCY VIRUS'S GLYCOPROTEIN 120 PROBE TO PREVENT AND TREAT AN INFECTION CAUSED BY THE HUMAN IMMUNODEFICIENCY VIRUS - The human immunodeficiency virus poses a significant threat to the health and well being of the world's population. Current strategies utilized to eradicate this deadly pathogen have not been effective.

The protein subunit of the glycoprotein 120 probe extends from the surface of HIV and is the unique identifier of an HIV virion. When protein subunits of HIV's glycoprotein probe are exclusively presented to the immune system, the antibodies generated will neutralize the glycoprotein 120 probes located on the surface of HIV virions, such that the virus's virions then are incapable of engaging a T-Helper cell and thus the infectious threat posed by HIV is averted. | 09-03-2009 |
