Researchers highlight importance of motivating people to seek HIV testing

HIV infected patients whose treatment is delayed not only become sicker than those treated earlier, but also require tens of thousands of dollars more in care over the first several years of their treatment.

Despite progress in testing Americans for HIV, lack of federal/private insurance impedes expansion

With projections that human immunodeficiency virus (HIV) infection rates are increasing in some populations, former Surgeon General Dr. C. Everett Koop -- who charted the nation's policies on HIV/AIDS following the first deaths from AIDS in 1981 -- today issued a stern warning to the public health community: HIV/AIDS continues to be a major epidemic and requires a national mobilization to identify and provide immediate care for many Americans with HIV who remain undiagnosed -- an estimated 200,000 people.

New findings on Th17 cells pave way for human cancer treatment protocol

A recently identified immune cell that directs other cells to fight infection plays a critical role in regulating the immune system in both health and disease. Researchers from the University of Pennsylvania School of Medicine have discovered how a stimulatory molecule and a protein found on the membrane of another immune cell make T helper 17 cells multi-taskers of sorts. Th17 cells protect the body against infection and cancer, but are also culprits in some autoimmune diseases and out-of-control, cancerous cell growth.

Antigenics third quarter net loss decreases from $10.8 million to $5.9 million

Antigenics Inc. reported today its results for the quarter ended September 30, 2010. The company incurred a net loss attributable to common stockholders of $5.9 million, or $0.06 per share, basic and diluted, for the third quarter of 2010, compared with a net loss attributable to common stockholders of $10.8 million, or $0.13 per share, basic and diluted, in the third quarter of 2009.

Immune system may play a role in cancer therapies: Study

The immune system may play a critical role in ensuring the success of certain types of cancer therapies, according to a new study by researchers at the Stanford University School of Medicine. The research showed treatments that disable cancer-promoting genes called oncogenes are much more successful in eradicating tumors in the presence of a signaling molecule secreted by kind of immune cell called a T helper cell.

Cytheris initiates ORVACS Phase II clinical trial to study HIV infection

Cytheris SA, a clinical stage biopharmaceutical company focused on research and development of new therapies for immune modulation, today announced the initiation of Phase II clinical trial of the company's investigative immunomodulatory agent, CYT107 (rhIL-7), in combination with two potent antiretroviral drugs represented by the integrase inhibitor raltegravir (ISENTRESS- Merck & Co.) and the CCR5 inhibitor, maraviroc (SELZENTRY- ViiV Healthcare).

Study demonstrates chitosan/IL-12 is an effective anti-tumor immunotherapy

A new study by a University of Arkansas biomedical engineer and his colleagues at the National Cancer Institute demonstrates further promise for chitosan/interleukin-12 as an effective anti-tumor immunotherapy.

Researchers investigate mechanism of immune system to decipher gut-dwelling worms

A billion people living in underdeveloped areas around the world are infected with parasitic helminthes, worms that survive by residing in and feeding on their hosts. These infestations can cause chronic intestinal (and occasionally systemic) illnesses leading to long-term disability. Irah King and Markus Mohrs, biomedical researchers at the Trudeau Institute, are investigating illnesses caused by these gut-dwelling worms in an effort to decipher how immune cells send and receive signals that determine the specific immune response to mount.

Biologists determine three-dimensional structure of molecule involved in HIV, cancer

In a technical tour de force, structural biologists funded by the National Institutes of Health have determined the three-dimensional structure of a molecule involved in HIV infection and in many forms of cancer. The high-resolution structure sheds light on how the molecule functions and could point to ways to control its activity, potentially locking out HIV and stalling cancer's spread.

RDI launches HIV-TRePS system to predict patients’ response to HIV drugs

A ground-breaking system for predicting how individual patients with HIV and AIDS will respond to different drugs is launched today by RDI, a UK-based not-for-profit research group. The experimental system, called the HIV Treatment Response Prediction System (HIV-TRePS), is available free of charge over the Internet and helps physicians select the best treatment for their patients.

Researchers identify new type of cell that protects from immune system attack

Researchers at the Dana-Farber Cancer Institute in Boston have identified a new type of cell in mice that dampens the immune system and protects the animal's own cells from immune system attack.

Celldex Therapeutics presents initial clinical data on CDX-1401 cancer vaccine candidate at iSBTc meeting

Celldex Therapeutics, Inc. today announced that the Company presented initial clinical data on CDX-1401 at the 25th Annual Meeting of the International Society of Biological Therapy of Cancer (iSBTc) in Washington, DC. CDX-1401 is a novel antibody-based targeted cancer vaccine candidate being evaluated as a treatment for patients with melanoma and other cancers that are known to express the tumor antigen NY-ESO-1.

Research on immune system paves way to combat mother-to-infant HIV transmission

Researchers at Oregon Health &Science University may have uncovered a new weapon for combating HIV as it is passed from mother to newborn child. The research, which was led by researchers at OHSU's Oregon National Primate Research Center, will be published in the October 3rd online edition of the journal Nature Medicine.

Discovery suggest a new direction for designing vaccines for rare HIV infection

New discoveries about the immune defenses of rare HIV patients who produce antibodies that prevent infection suggest a novel direction for designing new vaccines. Researchers at Rockefeller University and colleagues have now made two fundamental discoveries about the so called broadly neutralizing anti-HIV antibodies, which effectively keep the virus at bay.

HIV infection mystery revealed

In a new discovery, Melbourne researchers have found a mechanism by which the HIV virus can affect people. According to co-head of the Burnet Institute's Centre for Virology, Sharon Lewin, scientists have found out how HIV entered a group of cells in which the virus tends to persist in spite of antiviral treatment that reduces the virus to undetectable levels.

Annals of Internal Medicine publishes GRACE study data on HIV therapy

Data from the GRACE study will be published in the September 21st issue of the Annals of Internal Medicine. GRACE is the largest-ever study of treatment experienced adult women with HIV-1 to examine gender differences in response to HIV therapy. Sponsored by Tibotec Therapeutics Clinical Affairs, a division of Centocor Ortho Biotech Services, LLC, the GRACE study enrolled 67 percent women, demonstrating that it is possible to recruit large numbers of women into U.S.-based HIV treatment studies.
