Novel Vaccine Approach Achieves “Functional Cure” of AIDS Virus in Monkeys

By Frank Blanchard, Staff Writer, and Jeff Lifson, Guest Writer

Scientists at the Oregon Health & Science University and the AIDS and Cancer Virus Program of the Frederick National Laboratory for Cancer Research have used a novel vaccine approach to achieve a “functional cure” and apparent eradication of infection with a monkey version of the AIDS virus.

New Approach for Producing and Purifying IL-15 Heterodimers That Have Potent Immune Effect

By Nancy Parrish, Staff Writer

Cytokines are proteins that play a crucial role in the human immune system by delivering messages that trigger the activation of immune cells to fight off attacks from viruses or other invaders.

Cristina Bergamaschi, Ph.D., NCI Center for Cancer Research, has been studying the mechanism of expression and function of a cytokine known as interleukin-15 (IL-15) for the last five years, in collaboration with Elena Chertova, Ph.D., and other researchers in the Retroviral Protein Chemistry Core (RPCC) of the AIDS and Cancer Virus Program (ACVP), Frederick National Laboratory for Cancer Research.

By Ashley DeVine, Staff Writer

Deborah Morrison, Ph.D., laboratory chief, Laboratory of Cell and Developmental Signaling, Center for Cancer Research (CCR), received an NIH Director’s Award in June “for major breakthroughs in elucidating the mechanisms of Ras/Raf signaling that will be critical for diagnosis and treatment of disease,” according to the NIH Director’s Awards Ceremony brochure.

She was nominated by Ira Daar, Ph.D., senior investigator, Developmental Signal Transduction Section, Laboratory of Cell and Developmental Signaling, CCR.

IL-27 Found to Play Significant Role in Conferring HIV Resistance

By Nancy Parrish, Staff Writer

The human immunodeficiency virus (HIV) targets specific immune cells in the body known as macrophages because these are the cells that eliminate foreign material such as bacteria or viruses. HIV is able to reproduce and spread throughout the body if it can avoid destruction by macrophages.

A recent study by Lue Dai, Ph.D., and colleagues revealed that the human cytokine IL-27 helps promote the body’s production of macrophages that are resistant to HIV. The study further found that IL-27 suppresses a gene known as SPTBN1, which facilitates the survival of HIV cells. This breakthrough research was recently published in the Journal of Experimental Medicine.

$200,000 Grants Awarded to CCR Researchers for HIV/AIDS Studies

By Nancy Parrish, Staff Writer

Earlier this year, the Office of AIDS Research (OAR) awarded two, two-year grants of $200,000 each to Anu Puri, Ph.D., and Robert Blumenthal, Ph.D., both of the Center for Cancer Research (CCR) Nanobiology Program, and to Eric Freed, Ph.D., of the HIV Drug Resistance Program, for their research on potential new treatments for HIV.
