Researchers discover identical antibiotic resistant genes in soil bacteria and in pathogens from clinics

Disease-causing bacteria's efforts to resist antibiotics may get help from their distant bacterial relatives that live in the soil, new research at Washington University School of Medicine suggests.

Deadly flu virus research may be published for the advancement of science but more risk assessment needed says WHO

According to the World Health Organization, the two controversial studies that explain how scientists mutated the H5N1 bird flu virus into a form that could cause a deadly human pandemic will be published only after experts fully assess the risks.

Symposium discusses links between genetic, epigenetic and environmental influences on autism

Two UC Davis MIND Institute researchers will lead a symposium on relationships between genetic, epigenetic and environmental influences on the development of autism in children during the American Association for the Advancement of Science (AAAS) Annual Meeting, Feb. 16 -18 in Vancouver, Canada.

Researchers discover class of proteins that detect 'painful touch'

In two landmark papers in the journal Nature this week, scientists at The Scripps Research Institute report that they have identified a class of proteins that detect "painful touch."

ACAAI allergists available to discuss risks associated with asthma

The tragic death of journalist Anthony Shadid due to asthma and allergies underscores the realities of these serious diseases. Allergists Stanley Fineman, MD, president of the American College of Allergy, Asthma and Immunology, (ACAAI), and James Sublett, MD, chair of the ACAAI Environment Committee are available to discuss the risks associated with asthma.

Scientists discover molecular mechanism behind MS relapses

Scientists have discovered a molecular mechanism that could help explain how multiple sclerosis (MS) and other autoimmune diseases can be exacerbated by the onset of an infection.

University of Georgia researcher to develop first Chagas vaccine for pets

Chagas disease is the single most common cause of congestive heart failure and sudden death in the world. The devastating parasitic infection affects millions of people throughout Central and South America. But as global travel increases, it's becoming a greater threat in the United States and Europe as well.

Scientists track initial steps of type 1 diabetes mellitus

Scientists have taken a remarkably detailed look at the initial steps that occur in the body when type 1 diabetes mellitus first develops in a child or young adult.

Exposure to common flame retardant may affect fertility and long-term memory

Mice genetically engineered to be susceptible to autism-like behaviors that were exposed to a common flame retardant were less fertile and their offspring were smaller, less sociable and demonstrated marked deficits in learning and long-term memory when compared with the offspring of normal unexposed mice, a study by researchers at UC Davis has found.

Biochemists determine first crystal structure of an immunoproteasome

Like a shredder, the immunoproteasome cuts down proteins into peptides that are subsequently presented on the cellular surface. The immune system can distinguish between self and nonself peptides and selectively kills cells that due to a viral infection present non-self peptides at their surface. In autoimmune diseases this mechanism is deregulated and the immune system also eliminates uninfected cells by mistake.

ACAAI, Teva Respiratory partner to bring free asthma screenings nationwide

The American College of Allergy, Asthma and Immunology (ACAAI) recognizes Teva Respiratory for its continued leadership and support of important educational issues related to respiratory health, particularly under diagnosed and poorly managed asthma and exercise-induced bronchoconstriction. ACAAI announced today that they will partner again this year with Teva Respiratory to bring free asthma screenings to communities nationwide.

Study underscores power of real-time cell monitoring to dissect pluridimensionality of GPCR signaling

A research team led by Dr. Michel Bouvier at the Institute for Research in Immunology and Cancer (IRIC) of the University of Montreal in Quebec, used the Roche xCELLigence SP Instrument to measure changes in cell response following ligand stimulation.

Tissues in SIV-infected monkeys can ramp up production of Tregs

Tissue in monkeys infected with a close relative of HIV can ramp up production of a type of T cell that actually weakens the body's attack against the invading virus. The discovery, in lymph nodes draining the intestinal tract, could help explain how the HIV virus evades the body's immune defenses.

Epigenetic mechanisms maintain tolerance in T cells specific for self antigens

At the most basic level, the immune system must distinguish self from non-self, that is, it must discriminate between the molecular signatures of invading pathogens (non-self antigens) and cellular constituents that usually pose no risk to health (self-antigens).

Promising compound may counteract HIV's ability to hijack CD59 protein

One of the frustrations for scientists working on HIV/AIDS treatments has been the human immunodeficiency virus' ability to evade the body's immune system. Now an Indiana University researcher has discovered a compound that could help put the immune system back in the hunt.

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.

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.

13 Feb 2012

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.

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.
