New system to deliver siRNA into primary cells

In technology that promises to one day allow drug delivery to be tailored to an individual patient and a particular cancer tumor, researchers at the University of California, San Diego School of Medicine, have developed an efficient system for delivering siRNA into primary cells.

Early use of antiretroviral treatment improves survival rate of HIV patients

A clinical study, led by researchers from University College Dublin, Ireland, and Stanford University, California, USA, with international collaborators, demonstrates that mortality rates of HIV patients can be almost halved when early antiretroviral (ARV) therapy is added to the treatment of AIDS-related opportunistic infections (OIs) such as pneumonia, meningitis or other serious bacterial infections.

Researchers unravel key mechanism in pathogenesis of osteoporosis

Osteoporosis, or bone loss, is a disease that is most common in the elderly population, affecting women more often than men. Until now, it was not clear exactly how the disease develops.

Chronic infection clearly linked to key immunity protein

The reason deadly infections like human immunodeficiency virus (HIV) and hepatitis C never go away is because these viruses disarm the body's defense system.

New therapy improves chances of living disease-free with neuroblastoma

A phase III study has shown that adding an antibody-based therapy that harnesses the body's immune system resulted in a 20 percent increase in the number of children living disease-free for at least two years with neuroblastoma.

Cytomegalovirus may cause high blood pressure

A new study suggests for the first time that cytomegalovirus (CMV), a common viral infection affecting between 60 and 99 percent of adults worldwide, is a cause of high blood pressure, a leading risk factor for heart disease, stroke and kidney disease.

Stress may indeed be a direct contributor to childhood obesity.

That's according to a new Iowa State University study finding that increased levels of stress in adolescents are associated with a greater likelihood of them being overweight or obese.

Vitamin D may play a role in bacterial vaginosis in pregnant women

Bacterial vaginosis (BV) is the most common vaginal infection in US women of childbearing age, and is common in pregnant women. BV occurs when the normal balance of bacteria in the vagina is disrupted and replaced by an overgrowth of certain bacteria.

HIV drugs from plants

A research team at Örebro University in Sweden has succeeded in changing the genes in plants so they can function as a vaccine against HIV.

Cimzia approved in U.S. for rheumatoid arthritis

UCB announced today that the U.S. Food and Drug Administration (FDA) approved Cimzia, the only PEGylated anti-TNF (Tumor Necrosis Factor), for the treatment of adult patients with moderately to severely active rheumatoid arthritis (RA).

Baylor Research Institute receives multi-million dollar grant to develop flu vaccine

Scientists at Baylor Institute for Immunology Research (BIIR) in Dallas, part of Baylor Research Institute (BRI) and the Baylor Health Care System, announced today that they received a renewal of a multi-million dollar grant from the National Institutes of Health (NIH) to design new vaccines to prevent influenza - including swine flu (H1N1).

Researchers demonstrate the immunological effects of ginseng

Researchers writing in BioMed Central's open access Journal of Translational Medicine have shown that the herb, much used in traditional Chinese and other Asian medicine, does have anti-inflammatory effects.

Scientists develop tool to study a deadly parasite’s histone code

In the Japanese art of paper folding, a series of folds can make the same sheet of paper into a ballerina or baby elephant. But try unfolding the baby elephant and making it into a ballerina. It's like trying to make a neuron from a kidney cell. Epigenetics, it turns out, isn't much different from this old Japanese art: Each fold, or epigenetic crease, both limits and permits further potential folds in a way that mirrors how epigenetic changes seal a cell's fate.

New insights into immune exhaustion

A main reason why viruses such as HIV or hepatitis C persist despite a vigorous initial immune response is exhaustion. The T cells, or white blood cells, fighting a chronic infection eventually wear out.

Clues about how blood forms could yield new strategies for treating blood diseases

Biologists have long wondered why the embryonic heart begins beating so early, before the tissues actually need to be infused with blood.

New mathematical model predicts immune response to influenza A virus

Researchers at the University of Rochester have developed a mathematical model to predict immune responses to infection with influenza A viruses, including novel viruses such as the emergent 2009 influenza A (H1N1). This model examines the contributions of specific sets of immune cells in fighting influenza A virus.
