Tenofovir associated with significant risk of kidney damage and chronic kidney disease

Tenofovir, one of the most effective and commonly prescribed antiretroviral medications for HIV/AIDS, is associated with a significant risk of kidney damage and chronic kidney disease that increases over time, according to a study of more than 10,000 patients led by researchers at the San Francisco VA Medical Center and the University of California, San Francisco (UCSF).

SAMHD1 protein cuts off raw material that HIV needs to create DNA and replicate

A protein that protects some of our immune cells from the most common and virulent form of HIV works by starving the virus of the molecular building blocks that it needs to replicate, according to research published online in Nature Immunology.

Preterm birth interventions should be tailored for underlying risk factors and pathways

In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting -, in Dallas, Texas, researchers will report findings that indicate that preterm birth interventions should be tailored for underlying risk factors and pathways.

Benefits of long-term Kineret therapy in people with NOMID

A new study shows that Kineret (anakinra), a medication approved for the treatment of rheumatoid arthritis, is effective in stopping the progression of organ damage in people with neonatal-onset multisystem inflammatory disease.

Organ transplant patients can benefit from cochlear implants

Cochlear implants may be a safe, effective option for some organ transplant patients who've lost their hearing as an unfortunate consequence of their transplant-related drug regime, researchers report.

Molecular secrets behind halofuginone's power

For roughly two thousand years, Chinese herbalists have treated Malaria using a root extract, commonly known as Chang Shan, from a type of hydrangea that grows in Tibet and Nepal. More recent studies suggest that halofuginone, a compound derived from this extract's bioactive ingredient, could be used to treat many autoimmune disorders as well. Now, researchers from the Harvard School of Dental Medicine have discovered the molecular secrets behind this herbal extract's power.

Length of residence in the U.S. increases risk of PTB among Hispanic women

The longer a Hispanic woman lives in the United States, the higher her risk of preterm birth (PTB), with nearly half of PTBs among Hispanic women occurring in those who were born in the U.S.

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.

Y chromosome may be the link that passes heart disease risk from father to son

The study, published in The Lancet, focused on genetic markers on the Y chromosome — which is present only in male DNA (women have two X chromosomes) — and found that men with a certain genetic variant were 50% more likely to have coronary artery disease than those without it. The increased risk was independent of other contributors to heart disease such as age, weight, high cholesterol, high blood pressure and smoking.

Study investigates how cytokine IFN-λ release is regulated

In new research appearing in this month's issue of the journal Nature Immunology, Roy Curtiss, director of the Center for Infectious Diseases and Vaccinology at the Biodesign Institute at Arizona State University, along with international collaborators, investigates the coordination of a particular type of immune response, involving the release of of IFN-λ- a cell-signaling protein molecule known as a cytokine.

Scientists discover ferocity of immune system after viral infection

A scientific team led by researchers at the University of Geneva (UNIGE) and the Charité Berlin Medical University has made a completely unprecedented discovery showing how much our immune system is provoked into action when confronted by viral intruders.

Gene therapy to promote remyelination in mouse model of MS

Our bodies are full of tiny superheroes-antibodies that fight foreign invaders, cells that regenerate, and structures that ensure our systems run smoothly. One such structure is myelin-a material that forms a protective, insulating cape around the axons of our nerve cells so that they can send signals quickly and efficiently. But myelin, and the specialized cells called oligodendrocytes that make it, become damaged in demyelinating diseases like multiple sclerosis (MS), leaving neurons without their myelin sheaths.

IKBKE protein plays two roles in tobacco-related NSCLC

Researchers at Moffitt Cancer Center in Tampa, Fla., have discovered that the immune response regulator IKBKE (serine/threonine kinase) plays two roles in tobacco-related non-small cell lung cancers. Tobacco carcinogens induce IKBKE and, in turn, IKBKE induces chemotherapy resistance.

BGI and VIB's genomics meeting to take place on Feb. 15

Both organizations are already collaborating on several projects, including the mapping of the genomes of more than 1,000 species of gut bacteria, compiled from 577 billion base pairs of sequence data. The leading scientific journal Science selected this work as one of the scientific breakthroughs of 2011. Large-scale genome sequencing is becoming ever more important in life sciences, healthcare and agricultural research.

Early-life farm environment increases number of regulatory T-lymphocytes

Immunological diseases, such as eczema and asthma, are on the increase in westernised society and represent a major challenge for 21st century medicine. A new study has shown, for the first time, that growing up on a farm directly affects the regulation of the immune system and causes a reduction in the immunological responses to food proteins.
