New insights into how to combat avian flu

An in-depth analysis of blood from patients recovering from the H5N1 avian influenza virus has provided important insights into how to combat the potentially lethal virus.

microRNAs manipulate cells to one day create safe embryonic-like stem cells

A team of UCSF researchers has for the first time used tiny molecules called microRNAs to help turn adult mouse cells back to their embryonic state.

New HIV drug may help patients not responding to treatment

A potential treatment for HIV may one day help people who are not responding to Anti-Retroviral Therapy, suggests new research published tomorrow in The Journal of Immunology.

Mylan's Matrix receives tentative FDA approval under PEPFAR for generic Truvada

Mylan Inc. has announced that Matrix Laboratories Limited, its India-based subsidiary in which it holds a 71.2% controlling interest, has received the first tentative approval from the U.S. Food and Drug Administration (FDA) under the President's Emergency Plan for AIDS Relief (PEPFAR) for its Abbreviated New Drug Application (ANDA) for Emtricitabine and Tenofovir Disoproxil Fumarate Tablets, 200 mg/300 mg.

The spread of drug resistant HIV-1

Drug-resistant forms of HIV can be spread between individuals who have not received anti-retroviral treatment, according to Professor Deenan Pillay from University College, London and the Health Protection Agency, speaking at the Society for General Microbiology meeting at Harrogate.

Suberoylanilide hydroxamic acid 'turns on' latent HIV

HAART (highly active anti-retroviral therapy) has emerged as an extremely effective HIV treatment that keeps virus levels almost undetectable; however, HAART can never truly eradicate the virus as some HIV always remains dormant in cells.

Long-defunct gene comes back to life in humans

Researchers have discovered that a long-defunct gene was resurrected during the course of human evolution.

A new monkey model for HIV

By altering just one gene in HIV-1, scientists have succeeded in infecting pig-tailed macaque monkeys with a human version of the virus that has until now been impossible to study directly in animals.

New understanding of Ebola virus and tetherin protein

Researchers at the University of Pennsylvania School of Medicine have likely found one reason why the Ebola virus is such a powerful, deadly, and effective virus.

Gene therapy for rheumatoid arthritis: promising results

Researchers have reported the first clinical evidence that gene therapy reduces symptoms in patients with rheumatoid arthritis, an important milestone for this promising treatment which has endured a sometimes turbulent past.

Potential new target in the war on HIV/AIDS

The study revealed that a variant of a protein involved in HIV pathogenesis can suppress production of an HIV protein, known as Nef. Nef is required for the human immunodeficiency virus to develop into AIDS through a series of complex events involving viral elements and cellular proteins. Nef has never been a target for drug treatment in HIV patients.

Discovery of more efficient way to create induced Pluripotent Stem (iPS) cells

A Boston University School of Medicine-led research team has discovered a more efficient way to create induced Pluripotent Stem (iPS) cells, derived from mouse fibroblasts, by using a single virus vector instead of multiple viruses in the reprogramming process.

Biologist finds plant polymerases IV and V are really variants of polymerase II

It's a little like finding out that Superman is actually Clark Kent. A team of biologists at Washington University in St. Louis has discovered that two vital cellular components, nuclear RNA Polymerases IV and V (Pol IV and V), found only in plants, are actually specialized forms of RNA Polymerase II, an essential enzyme of all eukaryotic organisms, including humans.

Experts warn Australia is surrounded by a ring of disease hot-spots

Australian biosecurity experts have warned that Australia is surrounded to its north by a 'ring of fire' where new human and animal plagues could appear with very little warning and with potentially dire consequences.

Roche's new dual-target HIV-1 test approved in Europe

Roche announced today that its innovative dual-target HIV-1 test has received CE Mark certification, allowing it to be sold for clinical use in the European Union. The COBAS AmpliPrep/COBAS TaqMan HIV-1 Test, v2.0 utilizes a unique design to simultaneously amplify and detect two separate regions of the HIV-1 genome.

Blocking immune receptor molecule improves response to HIV-like virus, prolongs survival in monkeys

By blocking PD-1 (programmed death-1), an immune receptor molecule known to inhibit the immune response to chronic viral infections, scientists have safely and significantly reduced the plasma viral load and also prolonged survival of rhesus macaque monkeys severely infected with simian immunodeficiency virus (SIV), the nonhuman primate version of human immunodeficiency virus (HIV).

Potential new target for drugs to prevent HIV-associated dementia

A new study led by researchers at Albert Einstein College of Medicine of Yeshiva University has clarified how two major variants of HIV differ in their ability to cause neurologic complications.

Why HIV treatment makes people more susceptible to metabolic complications

Clinicians have known for some time that people treated for HIV also become much more susceptible to diabetes and heart disease.

New gene-silencing pathway found in plants

Biologists at Washington University in St. Louis have made major headway in explaining a mechanism by which plant cells silence potentially harmful genes.

Previously unknown regulatory step during HIV replication provides potential new target for HIV/AIDS therapy

A previously unknown regulatory step during human immunodeficiency (HIV) replication provides a potentially valuable new target for HIV/AIDS therapy, report researchers at the Salk Institute for Biological Studies and the University of Wisconsin, Madison.
