HDAC inhibitors flush latent HIV infection from hiding

A team of researchers at the University of North Carolina at Chapel Hill have successfully flushed latent HIV infection from hiding, with a drug used to treat certain types of lymphoma.

Only about 75% of U.S. HIV/AIDS patients remain in care consistently

Only about 75 percent of HIV/AIDS patients in the United States remain in care consistently, according to new research from the Perelman School of Medicine at the University of Pennsylvania published online this week in AIDS. The study of patients across the United States is the first to provide a comprehensive national estimate of HIV care retention and information about patients who are most likely to continue their treatment over time.

CD4 T cells can directly kill HIV-infected cells

A subpopulation of the immune cells targeted by HIV may play an important role in controlling viral loads after initial infection, potentially helping to determine how quickly infection will progress. In the February 29 issue of Science Translational Medicine, a team of researchers from the Ragon Institute of Massachusetts General Hospital (MGH), MIT and Harvard describe finding a population of HIV-specific CD4 T cells - cells traditionally thought to direct and support activities of other immune cells - that can directly kill HIV-infected cells.

Study reveals immune mechanism for surveillance over EBV infection

Some 90 percent of people are exposed to the Epstein Barr virus (EBV) at some point in their life. Even though it is quickly cleared from the body, the virus can linger silently for years in small numbers of infected B cells.

Starving HIV virus could be the basis for future therapy: Study

In a medical breakthrough researchers at NYU Langone Medical Center and colleagues have shown how some cells in the body can repel attacks from HIV by starving the virus of the building blocks of life.

Study reveals how SAMHD1 works to protect dendritic cells from HIV virus

A novel discovery by researchers at NYU Langone Medical Center and colleagues reveals a mechanism by which the immune system tries to halt the spread of HIV. Harnessing this mechanism may open up new paths for therapeutic research aimed at slowing the virus' progression to AIDS. The study appears online ahead of print today in Nature Immunology.

Antiretroviral therapy does not increase severity of psychiatric disorders

A study of more than 300 children and adolescents with human immunodeficiency virus (HIV) revealed no association between specific antiretroviral therapy and the severity of psychiatric disorders.

Anti-HER2 dendritic cell vaccine shows promise against DCIS

Researchers at the Perelman School of Medicine at the University of Pennsylvania report that a short course of vaccination with an anti-HER2 dendritic cell vaccine made partly from the patient's own cells triggers a complete tumor eradication in nearly 20 percent of women with ductal carcinoma in situ (DCIS), an early breast cancer.

Study investigates immune response in cancer

In a study investigating immune response in cancer, researchers from Moffitt Cancer Center in Tampa, Fla., and the University of South Florida have found that interaction between the immune system's antigen-specific CD4 T cells and myeloid-derived suppressor cells (MDSC) - cells that play a major role in cancer-related immune suppression - dramatically change the nature of MDSC-mediated suppression. By contrast, the same effect was not observed when MDSCs interacted with the immune system's CD8 T cells.

Positive results from BioCryst's BCX4208 Phase 2b study on gout

BioCryst Pharmaceuticals, Inc. announced long-term results from the extension phase of its randomized Phase 2b study of BCX4208 added to allopurinol in patients with gout who had failed to reach the serum uric acid (sUA) therapeutic goal of <6 mg/dL on allopurinol alone.

Antigen Express to move AE37 cancer vaccine into larger clinical trials

Generex Biotechnology Corporation today provided an update to the clinical development & regulatory strategy for its cancer vaccine, AE37.

Immediate ART appears preferable to deferring treatment among recently infected HIV patients

Among people recently infected with HIV, immediate antiretroviral therapy (ART) appears preferable to deferring treatment, according to a new study published in The Journal of Infectious Diseases and now available online.

Virco Lab launches HIV/AIDS EHR technology

Virco Lab, Inc., the U.S. affiliate of Virco BVBA, today announced the launch of AVIGA and AVIGA REPORTER. AVIGA is a web-based electronic health record (EHR) solution with HIV/AIDS disease-specific functionality and AVIGA REPORTER is a web-based, data-reporting module designed specifically for the purposes of conducting HIV/AIDS research and providing reporting capabilities.

Fresh cells can pep talk immune cells exhausted by HIV or hepatitis C

Chronic infections by viruses such as HIV or hepatitis C eventually take hold because they wear the immune system out, a phenomenon immunologists describe as exhaustion.

Aethlon Hemopurifier can capture Nef protein exosomes linked with HIV

Aethlon Medical, Inc., the pioneer in developing therapeutic filtration devices to address infectious disease and cancer, announced today that researchers have discovered that the Aethlon Hemopurifier is able to capture particles known as Nef protein exosomes, which contribute to the progression of human immunodeficiency virus (HIV) infection to acquired immunodeficiency syndrome.

Researchers discover how bloodstream malaria infection manipulates immune system

University of Iowa researchers and colleagues have discovered how malaria manipulates the immune system to allow the parasite to persist in the bloodstream. By rescuing this immune system pathway, the research team was able to cure mice of bloodstream malaria infections.

Treatment with leukemia patients' own cells may prevent infections after chemotherapy

A new treatment using leukemia patients' own infection-fighting cells appears to protect them from infections and cancer recurrence following treatment with fludarabine-based chemotherapy, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

Headache affects one of every two HIV/AIDS patients

A University of Mississippi study of headaches among HIV patients is being hailed as a critical step to improving treatment and reducing unnecessary medical costs among sufferers.

Mayo Clinic in Florida now offers kidney and pancreas transplants for HIV-positive patients

Mayo Clinic in Florida is now offering kidney and pancreas transplants to HIV positive patients with advanced kidney disease and diabetes. Evidence is now solid that HIV-positive patients have the same favorable outcome in terms of patient and allograft survival as non-HIV positive organ transplant recipients, says Mary Prendergast, M.D., a kidney specialist whose focus is the care of patients who receive kidney and pancreas transplants.

Moffitt investigators to participate with 16 oral and 50 posters presentations at 53rd ASH meeting

When the American Society of Hematology convenes its 53rd Annual Meeting and Exposition on Dec. 10-13 in San Diego, Calif., researchers from Moffitt Cancer Center will break a new record for Moffitt participants with one plenary presentation, 16 oral presentations and more than 50 poster presentations on new research results in a variety of meeting programs that focus on blood cancer basic science and clinical applications, including bone marrow transplantation and clinical trials results.
